feat(infra): Infrastructure → Google Cloud page

[JeremyFunk]

Top of the Google Cloud integration stack. Merge order: bottom up.

Adds Infrastructure → Google Cloud (/infra/gcp) at the feature level of the Railway and Cloudflare infrastructure pages: a health band and one table per curated service built from the gcp.* metrics, a page per workload with its charts, the resource inventory from gcp_resources, and the workloads on the Infrastructure overview and the service map.

Parity matrix

What each infrastructure integration has. "Before" is this PR as first opened (tables only).

Feature	Railway	Cloudflare	PlanetScale	Kubernetes / hosts	Google Cloud before	Google Cloud now
Summary above the list	Fleet band: services by peak of limit	KPI tiles: requests, 5xx rate, cache hit, bandwidth	KPI tiles: databases, branches, worst gauges	Fleet band: saturated, elevated, stale	None	Fleet band over every service: saturated, elevated, erroring

Google Cloud now has everything Railway and Cloudflare both have, and the cheap extras: the scope cells, the rail panel, the links out, and the service map panel.

The index page

• Band above the tabs, the FleetBand Railway and the hosts page use: every service's workloads in the selected project and region, split healthy, elevated and critical, with three cells that narrow the tables. Saturated: a percent column (every one is a share of a limit or of capacity) at 90% or more. Elevated: 60% or more. Erroring: an error rate of 1% or more over at least 100 events, the thresholds errorRateLevel and utilizationLevel already set for the rest of the app.
• Tabs are the link tab strip Hosts, Kubernetes and Alerts use (UnderlineTabStrip; UnderlineTabCount for the count a band cell adds), so height, gap, underline and divider are theirs. The strip sits in the page below the band, not in the header slot those pages use: the band counts every tab, so under header tabs it reads as the selected tab's, and the tab list is only known once the fleet has loaded. On a phone it scrolls sideways. All tabs are read at once (one presence probe, then one query per reporting service), which is what lets the band count every service and a tab switch read nothing.
• Tables: rows are links to the workload's page; a name search (q), a project and a region filter and the band's scope are in the URL and carry across tabs. The filters show once there is more than one project or region; the region filter is left off the Pub/Sub and Load Balancing tabs, whose resources are global. A VM's zone counts as its region. With a band cell active each tab shows how many of its workloads it holds. A Cloud SQL instance is named without the project Cloud Monitoring puts before it.
• Resources: a row that is one workload (a Cloud Run service, a 1st gen function, a VM, a Cloud SQL instance, a subscription) opens that workload's page.

Workload pages

/infra/gcp/$service/$name, with the rest of the workload's identity as readable search params (?project=…&region=…). Built from PageHero, StatRail, ChartCard and InfraMetricChart, as the Railway page: every chart is a line chart, with the legend in the card header.

Service	Charts
Cloud Run	Requests by response class, 5xx rate, request latency p50/p95/p99, instances (active, idle), CPU utilization p50/p95/p99, memory utilization p50/p95/p99, peak concurrency per instance p50/p95/p99, billable instances
Cloud Functions	Executions by status, error rate, execution time p50/p95/p99, instances (active, idle), memory per execution p50/p95/p99, network egress
GKE	CPU cores, CPU of limit, memory (non-evictable, evictable), memory of limit, restarts; then the cluster's nodes: CPU and memory of allocatable
Compute Engine	CPU utilization, memory used (E2 only), network received and sent, disk read and written
Cloud SQL	CPU, memory and disk utilization, connections, disk read and write operations, replica lag
Pub/Sub	Backlog, age of the oldest unacked message, delivered and acked per second, dead-lettered, push requests by response, push error rate
Load Balancing	Requests by response class, 5xx rate, total latency p50/p95/p99, backend latency p50/p95/p99, backend requests by response class, request and response bytes per second

• Units: shares as percent with the 80% rule, bytes and bytes per second (named in the chart title, bare sizes on the axis), milliseconds (replica lag and message age are converted from seconds), cores, per-second rates for counters including the by-class charts, plain counts for instances, connections and messages (a new count chart unit). A rate divides by the part of the first and last bucket the range covers.
• Silence is drawn as silence. A Cloud Run service scaled to zero reports nothing. Every bucket between the first and the last the workload reported in is kept: a counter reads zero there, every other line has a gap, and a value between two gaps is a dot. InfraMetricChart takes this as an opt-in gaps prop; its other callers are unchanged.
• The four tiles say what they are: total in range, average in range or share in range.
• A chart a workload can never fill says why (E2 machine types only., Read replicas only., Push subscriptions only.).
• Inventory panel in the right rail when the workload is exactly one inventory row by asset type, project, last name segment and, where the workload has one, location: type, name, project, location, state, labels, and a link to the product's list page in the Google Cloud console, opened on the resource's project (VM instances in Google Cloud). A GKE container shows its cluster. Zero or several candidates show no panel.
• Links: Logs (the workload's service.name; a managed service opens gcp/<resource type> narrowed by the identifying resource attribute: a URL map opens gcp/http_load_balancer, the type Cloud Logging writes, and a subscription is matched by its full path, which is how Cloud Logging labels it), Traces when the service overview lists a service of that name in the range, and beside each chart title its metric in the metrics explorer, filtered to the workload (service.name, or the resource attribute for a managed service) and grouped by percentile or label as the chart is.

Elsewhere in the product

• Infrastructure overview: the Google Cloud row has the health strip and up to three findings (critical first), each opening the workload's page. While everything is healthy it still names the services that report. A service whose read failed is a finding of its own (Pub/Sub metrics could not be read, opening that tab) and leads the row's headline; when no service could be read, the row shows the failed-read state every other source has.
• Service map: the detail panel of a traced service shows a Google Cloud section when a Cloud Run service, function, GKE container or VM reports under the same name: the first four columns of its row (totals marked as such) and a link to its page. It reads nothing unless a connection collects metrics.

Numbers on the integration page

The connected integration page opens with a row of numbers, like the Cloudflare page's (gcp-usage-cards.tsx, rules in gcp-usage.ts with tests). No new endpoint, query or table: every number comes from a read another page already makes.

Tile	Source	What it reads
Log entries · 24h, with hourly bars and an hourly average	The Logs page's volume query (customChartTimeSeries, source: logs, hourly, grouped by severity) with the resource attribute filter maple_ingest_source = gcp-logpush, the stamp ingest puts on every forwarded entry	The raw logs table for the org and the last 24 hours. No rollup carries the ingest source, so the filter is the same index-assisted attribute predicate the Logs page runs for that filter. One read per page view, 30 s stale time
Errors · 24h (Warnings · 24h when logs deliver alone)	The same read: the severities of its series	Nothing more
Workloads · 24h	getGcpInfraFleet over 24 hours: the presence probe on metric_catalog, then one query per reporting service	What the Infrastructure overview reads for its Google Cloud row
Resources (Projects when metrics deliver alone)	GET /internal/integrations/gcp/resources without filters	Postgres: totals, types and projects of the inventory

• The row follows what has delivered: both capabilities give four tiles, one alone gives three of its own, nothing delivered gives none. A number that cannot be counted yet is a dash.
• Under the row, Workloads by Google Cloud service links each reporting service to its tab here. Each connection's metrics line links to this page; its log line opens Logs filtered to the entries stamped with that connection's id.
• Numbers are per organization, not per connection: a count per connection would be one raw-log read per connection.
• A 24-hour total leaves out the partial first hour, as the volume chart does.
• A tile whose read fails says so; the status below it does not depend on any of these reads.
• The three prompts and the notice of this page that told the reader to switch metrics on, or to open the setup script, now name Configure (copy only).

Queries

Three builders in packages/query-engine-integrations/src/gcp/gcp-infra.ts, all through WarehouseQueryService.compiledQuery() and pinned in the SQL baseline.

• gcpInfraMetricsSQL(service) (unchanged SQL): one query per tab. Scans metrics_sum and metrics_gauge, each filtered by OrgId, MetricName IN (that table's curated names of the service's group) and TimeUnix in the range, grouped by identity, metric and label. Capped at 10,000 rows.
• gcpInfraTimeseriesSQL(source, keys) (new): one query per workload page, serving every chart and the headline tiles. The same two scans with the same OrgId, metric-name and time bounds, plus one equality per identity attribute of the workload (ResourceAttributes[...] = '<value>', 2 to 5 of them), grouped by toStartOfInterval(TimeUnix, bucket), metric and label. At most about 100 buckets (5-minute floor) times the group's metric and label values, capped at 10,000 rows. The GKE page issues it a second time for the gkeNodes source (2 metrics, the cluster's identity).
• gcpInfraPresenceSQL() (unchanged): the hourly metric_catalog rollup.

The index page, the overview row and the service map panel read the same getGcpInfraFleet: the presence probe, then gcpInfraMetrics once per reporting service (at most 7), concurrently. Before, the page read the probe and the open tab only.

Endpoints: POST /internal/query-engine/gcp-infra-timeseries (session-only; source is a closed literal, bucketSeconds is BucketSeconds, keys is at most 8 strings of at most 512 characters, the times are TinybirdDateTime). GET /internal/integrations/gcp/resources takes name, the last segment of the resource name, compared in SQL on the rows the org, type and project filters already narrowed; no index was needed.

No datasource, materialized view, poller, receiver or connector API change. No metric type was added.

Metrics parity would still need

Not added: every type costs the customer Cloud Monitoring reads, and the list belongs to #1333.

Metric or label	What it would enable
kubernetes.io/container/cpu/limit_cores, memory/limit_bytes, cpu/request_utilization, memory/request_utilization	Railway-style "of limit" meters with the limit named, and the request charts the Kubernetes pod page has
kubernetes.io/container series per pod (pod_name kept)	A pods-behind-this-container table, as the Kubernetes workload page has
agent.googleapis.com/memory/percent_used, disk/percent_used (Ops Agent)	Memory and disk utilization for VMs that are not E2
cloudsql.googleapis.com/database/up, database/memory/quota, disk/quota	An up/down state and absolute sizes beside the Cloud SQL shares
run.googleapis.com/request_count by revision_name	A breakdown by revision, the counterpart of Cloudflare's breakdown panel
pubsub.googleapis.com/subscription/ack_latencies, the subscription's topic_id	Ack latency, and the topic's publish rate on the subscription's page
loadbalancing.googleapis.com/https/frontend_tcp_rtt, internal and regional rule types	Client round-trip time, and load balancers that are not global external

Not built

• Sparklines on the band and fleet charts on the index (Cloudflare has both, Railway neither): both need a bucketed query over every service, which no existing builder serves.
• A filter sidebar with facet counts: two selects in the toolbar, the control the Resources tab already has, cover project and region.
• Service lens: Kubernetes only among the references.
• Meter bars and a last-seen column in the tables (Railway has them): the tables keep the numeric columns of the first version, as the Cloudflare tables do.
• A "more" row under the three overview findings (hosts have one): Railway and Cloudflare stop at three, and the source row beside them carries the count.
• Pub/Sub topic and Cloud Run job pages: topics have one metric and jobs none in the curated table.
• Resources rows for a GKE cluster, a URL map or a 2nd gen function open no page: a cluster is many containers, a URL map one page per backend, and a 2nd gen function's Cloud Run service name is derived by Google.
• An alert menu (PlanetScale only).

Empty and waiting states

State	Shown
No connection	Full-page prompt to connect, linking to Integrations → Google Cloud
Connections with metrics off, data in the range	The tabs with what was collected before, under a neutral notice Google Cloud metrics are off with Open the integration. No Resources tab: the inventory of a connection that stopped collecting is not listed
Connections with metrics off, no data in the range	Full-page prompt to turn metrics on under Configure and run the script
Metrics on, no connection's setup script has run	Full-page prompt Finish setting up Google Cloud with Open the integration; the page polls status every 10 s and moves on without a reload
The script ran, no read yet	Collecting your first Google Cloud metrics with a spinner and the 10-minute expectation, no status code and no button; the Resources tab polls while the inventory is empty
Reads fail and nothing was read in the last 10 minutes	Warning Maple can't read Google Cloud metrics with the message and Check the connection
A read from the last 10 minutes came with failed or cut-short queries	Warning Some Google Cloud metrics are missing with the message
No read for 30 minutes, no error	Warning Google Cloud metrics have stalled
Metrics arrive, none in the range	Banner asking to widen the range or reload; on a preset range the presence poll continues, so the tabs appear once the first metrics are queryable
A tab's service is quiet	Empty table row
Resource list incomplete (last_resources_error)	Notice above the Resources table only; it is not a metrics problem
?tab= names no tab	The first tab, not the error page
Inventory empty or filtered to nothing	Empty table row

These call gcpMetricsState from the integration card, so the page and the card cannot disagree. A Google Cloud console address in a failure message is a named link.

New on a workload page: chart skeletons while loading, the shared error state when the query fails, No metrics arrived for this <noun> in the selected window. when the workload did not report (the inventory panel still shows), and a per-chart message when one metric is absent. An unknown $service opens the list. A tab whose query failed says so in its table instead of reading as empty.

Inventory read path

• GcpConnectorService.resources(orgId, { assetType?, projectId?, name? }), served by GET /internal/integrations/gcp/resources (session-only, filters are bounded strings).
• Org scoping goes through gcp_connectors.org_id joined on the primary key prefix (connector_id, …), so no new index is needed.
• Returns the first 500 matches by asset type and name, the total match count, and the facets of the whole inventory (types with counts, project ids). Overlapping connections list a resource once per connection; it is shown and counted once, from the freshest sync.
• A connection with metrics switched off keeps its last inventory in the table but is left out of the read.
• No join between inventory and metrics: a workload page asks for its one resource by type, project and name.

Decisions

• Rows are returned long and folded in the browser instead of one hand-written wide query per service. One generic builder serves seven tabs, and adding a column needs no backend change. The cost is a larger payload and an alphabetical cap instead of a top-N by a metric.
• The inventory endpoint is internal although the connector API is v2. docs/api-v2.md says so.
• Nav preview: a seventh glyph would have dropped the closed Infrastructure row's miniatures. The preview now skips the child that is the section's own page (Overview), so it still draws six.
• routeTree.gen.ts is staged with the generator's lines for the two routes and nothing else: the route cannot typecheck without them.
• CI path filter: the ClickHouse SQL catalog sweep analyzes the integration builders but did not trigger on packages/query-engine-integrations/**, so it was skipped on this PR's first run. The filter now includes that path; the sweep ran and passed against ClickHouse 26.2.
• Default range is 1 hour.
• Health is read off the columns. Every percent column is a share of a limit or of capacity and every errorRate column carries its event count, so the band, the table colors, the overview findings and the workload tiles share one rule and no service has thresholds of its own.
• One page type for seven services. A service is a list of chart specs (charts.ts); the page, the query and the endpoint are shared. A test checks every chart reads only metrics its page's query returns.
• Readable addresses. A workload's identity is /infra/gcp/<service>/<name>?project=…&region=…, by lower-cased identity label, with a round-trip test over every service.

Known limits

• Connections with overlapping scopes store each series once per connection, so the counters of those workloads read multiplied. The fix belongs in the poller.
• Means cover the minutes a series reported.
• The health band rates the average over the range, where Railway rates the peak: the tab query returns sums and counts, not maxima.
• The console link opens the product's list page, not the resource: Google documents the list pages (run/services, kubernetes/list, compute/instances, sql, cloudpubsub/subscription, net-services/loadbalancing/list) and not the per-resource addresses, and a link that might 404 was not worth it.
• A chart's explorer link filters by the workload's name only. Two workloads of one name in different projects or regions open together there.
• Shared behaviour this page inherits: a long workload name wraps in the top bar at phone width; an axis on a multi-day range labels hours without dates; byte ticks are binary (572 MB); a latency axis starts at 0μs.
• A percentile drawn over a bucket longer than a minute is the mean of the per-minute percentiles.

Visual smoke checklist

On an org with a Google Cloud connection that collects metrics, with a 7-day range:

• /infra/gcp: the band counts the workloads of every tab; each cell narrows the open tab, puts a count on every tab and stays when the tab changes; a second click clears it.
• Every service tab: rows open the workload page; the project and region selects appear once there are two of either; search, filters and scope survive a reload.
• Resources: a Cloud Run service, a VM, a Cloud SQL instance and a subscription row open their workload page; a project, a cluster and a URL map row do not.
• One workload page per service: four tiles each marked total, average or share, every chart in its unit (percent, bytes, bytes per second, milliseconds, cores, per second, counts), the 80% rule on shares of a limit, one cursor across the charts on hover.
• A Cloud Run service that scaled to zero: requests read zero between its bursts, latency and instances have gaps, a single burst on a 7-day range is a dot.
• A Compute Engine instance that is not E2 says E2 machine types only. in the memory card; a Cloud SQL primary says Read replicas only. in the lag card; a pull subscription says Push subscriptions only. twice.
• A GKE container's page ends with Nodes of <cluster> and two charts.
• The rail panel shows on a workload that is in the inventory, and its link opens the product's list page in the console on the resource's project.
• Logs opens the workload's logs (a subscription's and a URL map's too); Traces shows only for a workload whose name is a traced service; the icon beside a chart title opens that metric in the metrics explorer, filtered to the workload and grouped as the chart is.
• /infra: the Google Cloud row has a health strip, and a finding per flagged workload that opens its page.
• /service-map: the panel of a traced service named like a Cloud Run service has a Google Cloud section.
• 390px wide: the band stacks, the tables scroll sideways, the charts are one column.

After the merge with main

main moved Postgres to effect-orm (#1353) and landed two passes over the shared UI primitives (#1355, #1358). This branch merged them through the layers below.

• Inventory read on effect-orm. The same two statements: count(DISTINCT name) by asset type and project over gcp_resources JOIN gcp_connectors for the organization's metrics-enabled connections, and SELECT DISTINCT ON (asset_type, name) ... ORDER BY asset_type, name, last_seen_at DESC LIMIT 500. The name filter is still split_part(name, '/', -1) = $n, as a PG.sql template.
• Presence query. Its start bound is floored to whole seconds (utcSecondsParam), as main now does for every bound inside toDateTime() (fix: warehouse DateTime bounds, run_sql caller errors, Cloudflare 402 and chat rate-limit noise #1354): a bound with milliseconds does not parse there.
• Startup bundle. The index route's search schema spells out the three scope literals, as the hosts and Railway pages do, instead of importing them from the tab model. The import had put the tab model and the connection-state rules into every page's startup: 696.2 KB of initial JS against the 695 KB budget once main's own growth was merged in, 690.6 KB without it.
• List filters. main made the toolbar search default-size with default-size selects beside it; the project, region and type filters follow.
• Sibling primitives. The tab strip is UnderlineTabStrip (see The index page). A search, filter or scope that leaves nothing shows FilteredEmpty, as on the Railway and Hosts lists. Every error state has a title and a retry.
• Rendered again on 2026-10-10 from the stack top against a fresh database built by the new migrations: the integration page (nothing connected, healthy, the menu, both dialog stages, a pending change, failures) and the index, Resources and workload pages, at 1440 and 390. Compared with the approved screenshots, the differences are main's: icons inside buttons are 14px (16px before, 18px on a phone), and the list search is 32px high (28px before).

The preview's database

The preview's database was built by this stack's earlier drizzle-kit migrations, which are gone from the folder. The deploy applied the four folders it had not recorded without a reset: every statement of the two new migrations is IF NOT EXISTS, except the foreign key of gcp_resources, which was added under its new name next to the old one. On the preview that table therefore carries the same foreign key twice; a fresh database has it once. To remove the leftover there:

ALTER TABLE gcp_resources DROP CONSTRAINT gcp_resources_connector_id_gcp_connectors_id_fkey;

Review notes

Code reviews

Two read-only reviews of the parity work ran before the push (queries, endpoints and inventory; web), on top of the two from the first version of this PR.

Applied:

• The workload query compares ServiceName, the tables' second sort key column, so it reads the workload's rows instead of the org's (the name is the workload's own for compute and gcp/<resource type> otherwise, from one helper the web shares).
• Its conditions are a tuple again, so the query's param type keeps orgId and the time bounds.
• A rate divides by the part of the first and last bucket the window covers, so a counter chart no longer dips at its edges.
• One service's failing query no longer fails the page, the overview row and the service map panel: that service comes back empty and marked, and its tab says the read failed.
• A load balancer's chart links open its metrics (gcp/https_lb_rule), its Logs button its logs (gcp/http_load_balancer); the two names were one.
• The Cloud SQL connections chart links the metric the instance's engine reports.
• A refresh dims the tiles and charts together.
• URL map keeps its capitals in the no-metrics message; the docs say which charts draw percentiles and that region and scope apply to the service tabs.
• Maple review F3 (an empty type= or project= in the address broke the Resources read): an empty param is no filter.
• Leaner: split_part(name, '/', -1), ChartCardMessage instead of a local empty state, six exports dropped.

Not applied:

• Dropping the trailing, still-filling bucket: the newest points are worth more than a flat right edge, and the poller's five-minute delay would leave it short either way.
• Reading the connection status in the service map through gcpStatusQuery(): it would pull the integration catalog module into the service map; the sidebar hook builds the same atom inline for the same reason.
• GCP_INFRA_SOURCES.gkeNodes.title is unread: the record's type asks for it.

Rendered rounds

Two rounds of a reviewer who saw only screenshots (every tab and every workload page at 1440 and 390, the overview, the service map panel, and where each link landed), compared against the Railway and Cloudflare pages.

Round 1, applied:

• Lines were drawn across the hours a scaled-to-zero service reported nothing: silence is now zero for counters and a gap for everything else.
• The by-class charts were Cloudflare's stacked areas, whose outlines did not match the legend once a class was zero: they are lines per second now, and the Cloudflare component is untouched again.
• Explorer links for managed services opened every resource of the type, and blended the percentiles: they filter by the resource attribute and group by quantile or label.
• The Pub/Sub Logs link found nothing: Cloud Logging labels a subscription with its full path.
• Rate ticks were clipped (391 KB/s read 91 KB/s) and a small container's CPU axis read 0, 0, 0: fixed in InfraMetricChart and formatValueWithUnit, for every page that uses them.
• Legends moved into the card headers so plots in a row align; titles that wrapped were shortened; rate charts name their unit in the title.
• Overview findings are worst first within a tone and read orders-db-replica at 93% disk.
• Tiles say total, average or share; tabs show a count while a band cell is active; the region filter is off the global tabs; Cloud SQL instances lose the project prefix; the breadcrumb is three levels with the service as a chip; rail labels have a heading.

Round 2, applied:

• A single reporting bucket between two gaps drew nothing: it is a dot.
• Tile sublines fit a phone; the load balancer's Response size column is Bytes sent; the GKE chart is titled CPU cores; disk and instance series were renamed so their colors differ.

Not applied, from both rounds:

• The overview's words ok / elevated / saturated beside the page's Saturated / Elevated / Erroring: the overview has one vocabulary for every source, and its critical bucket holds Cloudflare's erroring zones too.
• Shared shell and formatters: the top bar at phone width, hour-only ticks on long ranges, binary byte ticks, 0μs, the 80% label over a line at 81%, rail values breaking mid-word.
• The GKE tile in millicores above a chart in cores: the table's format is the documented one, the chart's is the Kubernetes pages'.
• The Resources tab's order, missing sort and missing search: unchanged from the first version of this PR.

From the first version of this PR

Two read-only reviews ran before the PR was opened (queries, endpoints and inventory; web). Applied: the stale inventory of stopped connections is excluded, the freshest copy of a duplicated resource wins, the where-conditions keep their param types, the quiet state keeps polling on preset ranges, the inventory re-reads while empty and on connector changes, the tab strip no longer clips its underline, the overview knows the source, and guards for impossible states were removed.

Not applied:

• Maple review F1 (samples: Schema.Number would reject a quoted 64-bit count from a BYO ClickHouse): the response schema never sees the warehouse's wire value. The executor decodes every row through the query's derived row schema first, and count() derives the UInt64 codec, which unquotes it. gcp-infra.test.ts now pins that (samples: "60" decodes to 60).
• Maple review F2 (a required reported field breaks decoding of stored removed connections): not changed. The stored list was only ever written by pre-release builds of this stack, so no customer browser holds the earlier form. A stored value that does not decode is not an error either: Atom.kvs in sync mode skips a failed read and the atom keeps its default, the empty list.
• Maple review F4 (an empty project= or region= in the address emptied every service tab): fixed. The page reads the filter params once, with empty meaning unset, and the service tabs, the tab links and the Resources tab use that.
• Maple review F5 (summarizeGcp counted a service whose read failed as no workloads, so the overview read ok): fixed. Such a service is a finding and is named on the Sources row; with no service readable the source shows its failed-read state.
• De-duplicating metrics across overlapping connections in the tab query: it needs a per-timestamp group over the raw rows, and the duplication is the poller's to avoid.
• Keeping the sidebar entry and the overview row while metrics are switched off but collected data is still in range (raised in the final rendered check): both follow the switch through the status read the hub already makes, and following stored data instead would put a warehouse read into the nav hook. With metrics off everywhere the page opens by its address and shows what was collected.
• Handling metrics_available: false on the page: the nav row never appears there, and the integration card already explains it.

Verification

• Query tests (gcp-infra.test.ts, 10): the workload read is bounded by OrgId, the service's metric names, the time range, ServiceName and every identity attribute; a missing key compares as empty; quotes in a key are escaped; the node source reads gcp/k8s_node. The SQL baseline gains one fixture per source (8) and changes no existing query.
• GcpConnectorService.test.ts: the name filter matches the last segment only.
• Web unit tests: tabs.test.ts (36: health levels, the event floor, scopes, the identity round trip through the address, display names), charts.test.ts (16: every chart reads only metrics its page's query returns, rates, classes per second, silent buckets, edge buckets, the explorer's metric and grouping, the fold into the table row's numbers), inventory.test.ts (15: exact match, no match between two candidates, the resource-to-workload round trip, console pages, log, trace and explorer filters), summaries.test.ts (overview segments and findings), chart-utils.test.ts (the count unit, sub-millicore values).
• CI on the pushed commits: typecheck, lint, tests, the ClickHouse SQL catalog sweep and the web perf suites pass.
• Rendered against a local stack on 2026-10-09: the real project's metrics and logs for Cloud Run, GKE, Compute Engine and Pub/Sub, and synthetic series in the poller's row layout for Cloud Functions, Cloud SQL, a load balancer URL map and a Cloud Run service named like a locally traced service (the test project has none of those). Every tab, every workload page type, the overview, the service map panel and ten click-throughs (row, resource row, band cell, finding, Logs for a service and a subscription, Traces, two explorer icons, the service map panel), at 1440 and 390, in three capture iterations with two screenshot-only review rounds between them. The inventory rows and the synthetic series were seeded locally and removed afterwards.
• Not exercised: the console links against a signed-in console (they are the list pages Google's documentation links), hover states, and a connection with overlapping scopes.

End-to-end run

Final regression on 2026-10-10 against a real Google Cloud project at project scope, from the stack top.

• Passed: the first-time flow, the setup report, a real Cloud Run workload (percentiles and request counts equal to Google's for 22 consecutive minutes), switch changes, the log filter modes, customer-caused failures, and all disconnect paths.
• Not run: organization and folder scope, a real Cloud Shell session (a Cloud SDK container on bash 5.2 was used), non-admin views, and the plan-limit and rate-limit states.

🟢 Confidence 7/10 · likely safe to merge
Verified the tenant scoping, identity keys and label values against gcp/mapping.ts and the docs; the metrics response row schema is the one unverified wire shape.
_{quality 90/100 · 1 warning · tests partial · risk medium · 4/4 new units observable}

Adds Infrastructure → Google Cloud: presence and per-service metric queries, an org-scoped inventory read, and the web tables — correct and well pinned by tests, except the metrics response schema, which rejects the quoted 64-bit samples a BYO-ClickHouse org receives. The open WarehouseInvalidInputError in warehouse-query-atoms.ts is the Cloudflare zone query and is untouched here.

• gcpInfraMetricsSQL unions metrics_sum and metrics_gauge into one point per workload, metric and label
• gcpInfraPresenceSQL reads the hourly metric_catalog to decide which service tabs show
• GcpConnectorService.resources pages the inventory by asset type and name, org-scoped through gcp_connectors
• /infra/gcp renders one table per reported service plus a Resources tab

Held at 8 because a warning is open.

Adds packages/query-engine-integrations/** to the clickhouse test-lane path filter, so the SQL catalog sweep runs on integration-builder edits. Correct and safe. F1 (samples: Schema.Number) is unchanged at this head and still open; this CI-only change does not touch the WarehouseInvalidInputError issue.

Adds one test to gcpInfraMetricsSQL: the query's derived row schema decodes a quoted count() ("60" → 60). Safe to merge — the delta is a test, so it does not touch the open WarehouseInvalidInputError issue.

Adds the /infra/gcp page: two new warehouse builders (metrics + presence), two query-engine endpoints, a Postgres inventory read, and the nav/overview wiring, all pinned by tests and the SQL baseline. Nothing in the diff breaks a contract I could confirm; the open WarehouseInvalidInputError from warehouse-query-atoms.ts is not addressed here.

Adds the Infrastructure → Google Cloud page: one sortable table per curated GCP service over the gcp.* metrics, the Cloud Asset Inventory tab, two query-engine builders behind internal endpoints and the inventory read. Contained and safe to merge; the open WarehouseInvalidInputError in warehouse-query-atoms.ts is untouched by this change and the new reads cannot reach it (a validated time window and a closed service literal).

🟢 Confidence 9/10 · safe to merge
Label semantics, identity attributes and org scoping are pinned by the new tests and checked against the poller's own mapping; no hunk went unread.
_{quality 100/100 · no findings · tests covered · risk medium · 4/4 new units observable}

Adds Infrastructure → Google Cloud: a tab per curated gcp.* service plus the Cloud Asset inventory, two agents warehouse endpoints and an org-scoped inventory read. The queries, folding and facets are well tested and safe to merge. The open WarehouseInvalidInputError ("Breakdown query too broad without filters") comes from the breakdown query, not the two atoms this diff adds to that file, so the change does not address it.

• /infra/gcp renders one sortable table per reporting service tab plus the resource inventory
• gcpInfraMetricsSQL/gcpInfraPresenceSQL read the curated metrics and the metric_catalog rollup, both OrgId-scoped
• GcpConnectorService.resources returns the org's deduped, filtered inventory with type and project facets
• Google Cloud joins the Infrastructure nav and overview behind the metrics-enabled connector gate

_{quality 100/100 · no findings · tests covered · risk medium · 2/2 new units observable}

Adds Infrastructure → Google Cloud: a gated nav entry, /infra/gcp with one table per curated gcp.* service plus the Cloud Asset inventory, two warehouse query builders and a session-scoped inventory read. Safe to merge. The open WarehouseInvalidInputError issue (top frame warehouse-query-atoms.ts) is not addressed: this PR only adds two atom families to that file and changes no error path.

• gcpInfraMetricsSQL/gcpInfraPresenceSQL read gcp.* metrics and the hourly catalog
• GcpConnectorService.resources lists the org's inventory by connector
• /infra/gcp renders one tab per reporting service plus Resources
• gcp joins the Infrastructure nav and overview as a metrics-gated source

The three files changed since the last pass are additive UI glue around already-reviewed atoms; I read each hunk and every symbol it calls and found no defect.
_{quality 100/100 · no findings · tests partial · risk low · 3/3 new units observable}

Adds the Infrastructure -> Google Cloud page, its service-tab queries and the GCP resource inventory read path. The three hunks changed since the last pass are presentation and wiring only; nothing there warrants blocking the merge. The open @maple/web WarehouseInvalidInputError in warehouse-query-atoms.ts (cloudflareInfraZones) is untouched by this change: it adds two GCP atoms beside the existing ones and does not alter that path.

• GcpResources reads the inventory through retainedInternalQuery, keyed on the integration
• MetricsStatus on the integration card links to /infra/gcp when metrics are on
• GcpPage gates on metrics-enabled connectors and follows a settling connection every 10s

Only a browser test is new; the catchUp effect it pins reads correctly, and gcp-removed-connectors-atoms.ts:17 is unchanged so F2 stays open.
_{quality 88/100 · 1 warning · 1 note · tests covered · risk medium}

The one file changed since the last review adds a browser test pinning the catchUp branch of useIntervalRefresh and its listener cleanup; the hook reads correctly and the test asserts real behavior. F2 remains: reported is still required in RemovedGcpConnector, and the base branch already persists entries without it. The two open maple-web warehouse-query errors on QueryEngine.execute/WarehouseInvalidInputError are not addressed by this change.

• Probe in use-interval-refresh.browser.test.tsx takes catchUp and forwards it to the hook
• A browser test pins that only catchUp refreshes on visibilitychange, and that the listener goes on unmount

Adds the Infrastructure → Google Cloud page: GCP metric queries, API routes, domain schemas and the web routes, tables and charts behind it. Nothing I read showed a defect, but only 3 of 58 production files could be read, so a second pass is needed before merge. F7 is fixed; F2 stays open — its file is not in this diff.

• getGcpInfraFleet queries every reporting service, a failed one returned empty and failed

Preserve Cloud Functions execution entries when excluding application output.

If a user omits cloud_functions, gcpLogFilter(applicationLogs) excludes its entire log stream. That stream also contains execution start and end entries, so the sink drops platform entries that the request contract says it forwards regardless of the selection. Narrow the exclusion to application output before replacing the sink filter. (docs.cloud.google.com)

Reworks Google Cloud log forwarding: application_logs replaces log_filter, the dialog asks per runtime, and the script builds the sink filter from it, with tests on both sides. The errors attributed to lab/registry.ts are unrelated and untouched; the earlier reported warn stands.

• GcpLogFilterField ticks runtimes, opened only once OpenTelemetry is ruled out
• gcpLogFilter emits one NOT clause per runtime left out
• gcpLogFilterChoice sends application_logs only when the filter is replaced

🟡 Minor · Fix the Cloud Run step: it describes the old default. · gcp-opentelemetry.md:31

apps/landing/src/content/docs/integrations/gcp-opentelemetry.md:31
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Fix the Cloud Run step: it describes the old default.

Line 31 says that by default the connection forwards Cloud Run stdout and stderr. It also tells the user to untick Cloud Run. The current behavior is different:

• Line 45 says the connection forwards no application output by default.
• gcpLogFilterChoice starts a new sink with runtimes: [].
• The UI shows no runtime checkboxes until the user clicks Can't forward via OpenTelemetry.

A user who follows this step will look for a Cloud Run checkbox that is not shown. Change the step to say that no change is needed.

Proposed fix

-3. If the service exports logs over OpenTelemetry, untick **Cloud Run** under [**Log filter**](#change-the-filter): by default the connection forwards what a Cloud Run container writes to stdout and stderr.
+3. Leave **Log filter** as it is: by default the connection forwards no Cloud Run stdout or stderr, so logs exported over OpenTelemetry are not stored twice.

🌐 Web query:

Google Cloud GKE system pod logs resource.type k8s_container Cloud Logging system component logs official documentation

💡 Result:

In GKE, **system pod/container logs are generally queried with `resource.type = "k8s_container"`**. Google defines `k8s_container` as the resource type for Kubernetes container logs, and its sample query for GKE system logs includes both `k8s_container` and `k8s_pod`. ([docs.cloud.google.com](https://docs.cloud.google.com/kubernetes-engine/docs/how-to/view-logs?utm_source=openai))

To narrow results to system namespaces, try this Logs Explorer filter:

```text
resource.type = "k8s_container"
resource.labels.namespace_name = ("kube-system" OR "gke-system" OR "istio-system" OR "knative-serving" OR "config-management-system")
```

The namespace list comes from Google’s documentation on which Pods count as system logs. ([docs.cloud.google.com](https://docs.cloud.google.com/kubernetes-engine/docs/how-to/view-logs?utm_source=openai))

Note: GKE system logs can also include node services and serial-port output, so not every system log uses `k8s_container`. And control-plane component logs have their own resource type, `k8s_control_plane_component`. ([docs.cloud.google.com](https://docs.cloud.google.com/kubernetes-engine/docs/how-to/view-logs?utm_source=openai))

Narrow the GKE exclusion instead of only clarifying the documentation.

NOT resource.type="k8s_container" excludes GKE system-pod logs, including kube-system logs, as well as application output. Google classifies these system-pod logs as k8s_container resources. This conflicts with the documented promise that platform logs remain forwarded when GKE containers is unticked. Narrow the generated sink filter to exclude GKE application output while retaining system-pod logs, and update the corresponding filter expectations.

Review comment at @apps/landing/src/content/docs/integrations/gcp.md at line
279:
Update the GCP sink filter that generates the k8s_container exclusion so it
excludes GKE application logs without excluding system-pod logs such as
kube-system; update the corresponding filter expectations to verify both
behaviors.

🟢 Confidence 8/10 · likely safe to merge
The delta only removes the scope filter and band; greps show no caller or search param left behind.
_{quality 90/100 · 1 warning · tests covered · risk low}

Removes the health-scope filter and summary band from /infra/gcp: the scope search param, GcpScope/gcpInScope/GCP_SCOPES, GcpSummaryBand(Loading) and the per-tab scope counts are gone, tables filter by project and region only. It reads as a deliberate simplification of the earlier head, found no dangling callers, and is safe to merge; the open McpQueryError/IntegrationsUpstreamError/GithubAppError issues all frame in apps/web/src/lab/registry.ts, which this change does not touch, so it neither fixes nor worsens them.

• GcpServiceTable lost its scope prop; rows filter only by name, project and region
• GcpSummaryBand/GcpSummaryBandLoading deleted from the GCP infra index
• The scope search param left gcpSearchSchema; tab links no longer carry it

Still open from earlier reviews

🟡 Confidence 6/10 · needs attention
Query, domain and overview hunks read directly; the page, integration-card and connector hunks were read by child reviewers and I did not re-verify each one.
_{quality 88/100 · 1 warning · 1 note · tests partial · risk medium · 2/2 new units observable}

Adds Infrastructure → Google Cloud: three query-engine endpoints over the gcp.* metrics, the resource inventory endpoint, the index and workload pages, and rows on the overview and service map. It is contained and safe to merge once the overview finding is settled; the WarehouseInvalidInputError in warehouse-query-atoms.ts is not the path this adds, and its empty-filter trigger is guarded in the new route, which I did not verify end to end.

• gcpInfraMetricsSQL/gcpInfraTimeseriesSQL/gcpInfraPresenceSQL aggregate metrics_sum and metrics_gauge per workload and label
• Three /gcp-infra-* query-engine endpoints plus GET /v2/integrations/gcp/resources
• /infra/gcp index and /infra/gcp/$service/$name pages with the summaryGcp fleet band
• summarizeGcp and a service-map panel join GCP workloads into the infrastructure overview

🔵 Note · F9 · summarizeGcp appends unread-service rows past MAX_FINDINGS_PER_SOURCE

correctness · apps/web/src/components/infra/overview/summaries.ts:337-346

flagged is sliced to MAX_FINDINGS_PER_SOURCE (line 327) but the unread rows are concatenated un-sliced, so a fleet where several workloads are elevated and several services fail to read contributes more rows to the overview's needs-attention list than the cap every other source respects (summarizePlanetScale, line 347, caps the final list).

Build `findings` from `flagged.slice(0, MAX_FINDINGS_PER_SOURCE)` plus `unread`, then return `findings.slice(0, MAX_FINDINGS_PER_SOURCE + unread.length)` or cap the combined array so the unread rows cannot push the list past the cap.

🟢 Confidence 7/10 · likely safe to merge
The renamed stored metric names and the new direction label are pinned by gcp-infra.test.ts and charts.test.ts; F9's uncapped unread rows and F2 remain unfixed.
_{quality 88/100 · 1 warning · 1 note · tests covered · risk medium · 2/2 new units observable}

The changed hunks rename the curated GCP metrics to semconv-style names (gcp.cloud_run.requests, gcp.gce.network.io) and carry the byte-counter direction as a point attribute; charts, columns and queries move together and are pinned by tests. Nothing new to fix in these hunks, but F9 (unread-service findings appended past the cap) and F2 are still open, and warehouse-query-atoms.ts only registers the new atoms, so the open WarehouseInvalidInputError on that path is not addressed.

• GCP metric names follow semconv: gcp.cloud_run.requests, gcp.gce.network.io, gcp.cloud_sql.replication.lag
• Byte counters split by a network.io.direction / disk.io.direction attribute instead of one name per direction
• gcpMetricPointAttributes prefixes kept metric labels as gcp.metric.labels.<label> and drives chart groupBy
• gcpResourceAttributes adds gcp.gce.instance.name, service.name stays gcp/<resource type>

• Direction labels: mapping.ts:181 writes the point attribute and gcp-infra.ts:34 concats it as label, matching total(..., "receive")

Core models, queries and endpoints read and three child passes found nothing new, but several presentational web files went unread.
_{quality 98/100 · 1 note · tests partial · risk medium · 3/3 new units observable}

Adds the Infrastructure → Google Cloud pages: three query-engine endpoints over the gcp.* metrics, the Cloud Asset Inventory read, and the integration page rework. Safe to merge after the stack's lower PRs; the open WarehouseInvalidInputError is not addressed here. Not read: gcp-resources.tsx, gcp-workload-charts.tsx, gcp-usage-cards.tsx, gcp-configure.tsx, gcp-integration-card.tsx and the service-map canvas.

• /infra/gcp index and workload pages: fleet band, sortable service tables, resource inventory, charts
• New query-engine endpoints gcpInfraPresence/GcpInfraMetrics/gcpInfraTimeseries on the gcp.* metrics
• GET /internal/integrations/gcp/resources reads the Cloud Asset Inventory
• v2 setup scripts take application_logs runtimes instead of log_filter
