🔌 Plugin overview

  • Plugin name: PRTG Network Monitor (prtg)
  • Purpose / problem solved: Brings a PRTG estate into SquaredUp, so PRTG data sits on shared dashboards alongside other tools instead of only in the PRTG console. Probes, groups, devices and sensors are indexed and searchable. Sensor status, channel readings, historic data, the PRTG log and installation-wide status can all be queried.
  • Primary audience: Platform, infrastructure and network operations teams, and MSPs running PRTG across customer estates.
  • Authentication method(s): API key. A PRTG Scripting token with Read access, sent as the apitoken query parameter. PRTG's manual documents Authorization: Bearer, but PRTG rejects it in practice: Bearer, Authorization: apitoken and X-Api-Key all return 401 Unsupported authorization scheme on 26.3.122.1665. An optional Ignore certificate errors checkbox covers on-premise servers with self-signed certificates.

Reopened from its stale close. The plugin has been reworked since. See What changed since this PR was closed, and the review feedback responses in the comments below.


🔄 What changed since this PR was closed

  • The time zone setting is gone. PRTG reads date ranges in the API account's own time zone, and there is no per-request override. Instead of asking the user for that zone, Log and Sensor History now widen each request by 12 hours before and 14 hours after (the full range of real UTC offsets). They then trim to the exact timeframe using the UTC OLE timestamps PRTG puts on every row. This removes the serverTimeZone field, its save-time check and the timeZoneCheck data stream. Configuration is now just URL, API key and the certificate checkbox.
  • Sensor History reads historicdata.csv. Only the CSV (and XML) form carries both the channel names and Date Time(RAW). The JSON form either names every channel value or drops the raw date. Date Time(RAW) is the bucket end for averaged data, so the script subtracts the interval to plot the bucket start.
  • The object tables are paged. Probes, groups, devices and sensors, plus the two "in Probe/Group/Device" streams, fetch 500 rows per request. They page with an objid cursor, filter_objid=@above(<last objid>), not start. PRTG's start clamps to the last page once it passes the end, so offset paging never terminates. The root group (objid 0) is now filtered out in the script, not with a static filter_objid argument.
  • Status text is rebuilt from status_raw, because PRTG's display text varies by version (for example "Paused (paused by user)").
  • README corrections. The API v2 comparison was rechecked against Paessler's OpenAPI specification. System Status now labels UserTimeZone as Account Time Zone, because it is the API key's account zone, not the server's.

🧪 Test plan

Tested against PRTG Hosted Monitor 26.3.122.1665 (trial, one hosted probe, 42 sensors). The API account's zone is "GMT Standard Time", which runs at UTC+1 during BST, so any time zone mistake would show up as a clean one-hour shift.

Static: squaredup validate plugins/PRTG/v1 --json returns valid: true (10 data streams, 1 import definition, custom types, config validation, default content, icon).

Against the PRTG API directly:

Checked Result
filter_objid=@above(n) with sortby=objid Pages in objid order and returns [] past the end. Works together with filter_type=probenode and with id=<container>. start=1000 on 42 sensors returns the last page again, which confirms why offset paging never ended
historicdata.csv Date Time(RAW) UTC. A bucket shown as 7:10 – 7:15 AM local has RAW 06:15Z (the bucket end). With avg=0 it is the reading time
CSV trailing row "Averages (of N values)" has a non-numeric second cell, so it is skipped
Coverage(RAW) 0000010000 → 100, which matches the 0–100 percent shape. uptime_raw 1000000 / 10000 → 100 likewise
Log datetime_raw UTC: 10:19:53 AM local is 09:19:53Z

Deployed to a SquaredUp organization (data source against the trial):

Checked Result
Import 1 probe, 2 groups (root excluded), 5 devices, 42 sensors, matching PRTG
Probes / Groups / Devices / Sensors Full row counts, so the cursor paging terminates. Status, uptime, last check and scanning interval are correct
Log, last 7 days 258 rows, all inside the window, times in UTC. Last 24 hours is empty, which is correct: the newest entry was 24h08m old
System Status 39 up, 3 down, 42 total; version, edition and account time zone
Sensor History script Replayed against live CSV for a ping sensor. 5-minute and Raw modes both give correct UTC buckets that line up with the sensor's Last Check
Per-object dashboards Probe, Group, Device and Sensor perspectives (and Sensor History live) still to be confirmed in the UI before this leaves draft

⚠️ Known limitations

These mirror Known limitations in docs/README.md:

  • No graph relationships. Low-code plugins cannot create graph edges, so the hierarchy is stored as properties (parentId, deviceName, groupName, probeName) and used through dashboard scoping and drilldown.
  • Log counts on past windows can include extra entries against the cap. Because of the widened request window, up to 14 hours of newer entries can count towards the 5,000-entry limit before they are trimmed. Times themselves are always correct.
  • The log returns at most 5,000 entries, newest first. PRTG reports no usable total for the log, so truncation cannot be detected.
  • Very large installations may still hit the platform response size limit. Paging removes the per-request ceiling, but the combined result is still capped.
  • Sensor History is limited to 30 days. Without an averaging interval chosen, it uses hourly buckets beyond 7 days. Choosing 5 minutes or Raw on a long range can still exceed the response limit.
  • PRTG tags are indexed as a single prtgTags string, exactly as PRTG returns them (inherited tags included).
  • Location is only returned where it is set on the object itself, and never on sensors. There is no map visualisation.
  • API key in the query string. It is the only scheme PRTG accepts, so always use HTTPS.
  • Read-only. The plugin never modifies anything in PRTG.

📚 Checklist

  • This PR adds a single plugin only
  • Plugin, datastream and UI naming follow SquaredUp guidelines
  • Logo added (icon.svg, square 512×512)
  • One or more dashboards added (Overview, Sites, and a perspective for each of Probe, Group, Device, Sensor)
  • README added including configuration guidance
  • No secrets or credentials included (git history checked for the test key and hostname)
  • I agree to the Code of Conduct

Summary by CodeRabbit

  • New Features
    • Added PRTG Network Monitor integration with API-key connection settings and authentication validation.
    • Added monitoring data for probes, groups, devices, sensors, sensor channels and history, system status, and logs.
    • Added overview, site, probe, group, device, and sensor dashboards for exploring infrastructure health and activity.
    • Added object selection and indexing for PRTG probes, groups, devices, and sensors.
  • Documentation
    • Added setup guidance, supported data, configuration details, and known limitations for the PRTG integration.

Low-code plugin for the PRTG v1 HTTP API, indexing probes, groups,
devices and sensors, with ten data streams and six out-of-the-box
dashboards (estate overview, sites, and a perspective per object type).

Notes on a few non-obvious choices, all confirmed against a live
PRTG 26.3 instance:

- Reads the `_raw` variant of every text column. PRTG's display columns
  carry markup — `message` is `<div class="status">OK</div>`, `lastcheck`
  appends `<span class="percent">[165 s ago]</span>`.
- `table.json` OLE datetimes are UTC, so they convert directly.
  `historicdata.json` reports only server-local wall-clock text with no
  UTC equivalent, which is why the PRTG time zone is configurable and
  why that stream needs a post-request script.
- `content=channels` HTML-escapes `lastvalue` where `content=sensors`
  does not, so only Sensor Channels decodes entities.
- Sensor History averages hourly beyond seven days. Measured at the
  5-minute default, a 30-day range on a nine-channel sensor unpivots to
  roughly 7 MB and exceeds the response size limit.
- Sensor counts come back as empty strings rather than zero, hence the
  `Number(x) || 0` guards in System Status.

Merge Risk: 🟡 Moderate · up to eed3b

Dashboards can combine separate devices or show paused sensors as needing attention, and busy installations can lose requested log entries from the displayed results. Correct these issues before merging; the earlier log-timezone concern also remains unresolved.

Inline comments:
In @.github/CODEOWNERS:
- Line 17: Update the PRTG CODEOWNERS pattern from plugins/PRTG/* to
/plugins/PRTG/ so `@Deenk` owns files recursively under the entire PRTG plugin
directory.

In `@plugins/PRTG/v1/dataStreams/logs.json`:
- Around line 48-55: Update the time computed field’s valueExpression to
interpret datetime_raw in the configured serverTimeZone before converting it to
ISO 8601, while preserving the existing OLE epoch offset and null handling for
nonpositive values. Keep the change scoped to the time conversion and align its
zone handling with filter_dstart and filter_dend.

In `@plugins/PRTG/v1/dataStreams/probes.json`:
- Around line 99-103: Update the statusText mapping in
plugins/PRTG/v1/dataStreams/probes.json lines 99-103, groups.json lines 110-114,
devices.json lines 116-120, sensors.json lines 121-125, containerDevices.json
lines 128-132, and containerSensors.json lines 134-138 so status code 11 maps to
Not Licensed; add Not Licensed to unmonitored in each stream, then increment the
version in plugins/PRTG/v1/metadata.json.

In `@plugins/PRTG/v1/dataStreams/scripts/sensorHistory.js`:
- Around line 15-20: Update offsetAt to validate both the input instant and the
Date.parse result, returning null when either is non-finite; ensure
wallClockToUtc and parseWhen propagate or handle that null before calling
toISOString, preserving the existing successful conversion path.
- Around line 15-20: The locale-dependent date/time parsing must be replaced at
both sites. In plugins/PRTG/v1/dataStreams/scripts/sensorHistory.js lines 15-20,
update offsetAt to use Intl.DateTimeFormat.formatToParts for explicit date and
time components, and return null when the computed offset is non-finite so
parseWhen remains safe. In plugins/PRTG/v1/dataStreams/sensorHistory.json lines
22-29, construct sdate and edate as YYYY-MM-DD-HH-mm-ss from explicit formatted
parts instead of replace-based parsing.
- Around line 50-54: Update parseCoverage to preserve numeric zero by removing
the raw || '' fallback before string conversion; retain the existing percent
stripping, trimming, and null return for non-numeric values.
- Around line 12-13: Update the serverTimeZone interpolation in the TIME_ZONE
initialization to JavaScript-escape or serialize the resolved timezone value
before embedding it in the string literal, preventing quote-based script
injection while retaining the UTC fallback.
- Around line 31-48: Update parseWhen to prefer datetime_raw and convert its
OLE/Excel serial value using the existing logs.json conversion expression, while
retaining timezone handling. When datetime_raw is absent, parse datetime
explicitly according to the configured PRTG account format with component
validation rather than using new Date(start); also exclude datetime_raw and
coverage_raw from the channel iteration so they are not emitted as channels.

In `@plugins/PRTG/v1/dataStreams/sensorHistory.json`:
- Around line 104-111: Update the defaultTimeframe configuration in the sensor
history stream to use one of the supported timeframes listed in timeframes,
rather than dashboard; choose the appropriate supported default without changing
the existing timeframes list.

In `@plugins/PRTG/v1/docs/README.md`:
- Line 31: Update the authentication documentation around the API key entry and
the referenced authentication guidance so it describes API-key query-parameter
usage as this plugin’s constraint, without claiming that PRTG’s v1 API rejects
Bearer or username/passhash authentication.

In `@plugins/PRTG/v1/indexDefinitions/default.json`:
- Around line 12-98: Rename the indexed source type values in
plugins/PRTG/v1/indexDefinitions/default.json (lines 12-98) from PRTG-prefixed
names to the corresponding unprefixed PRTG object terms, including Probe, Group,
Device, and Sensor. Apply the same renamed values to every sourceType in
plugins/PRTG/v1/custom_types.json (lines 3-29) and every matches.sourceType in
plugins/PRTG/v1/scopes.json (lines 3-48), keeping all contracts consistent.

Correctness fixes:

- Map PRTG status code 11 to "Not Licensed" across all six object streams,
  and drop "Paused by License" from the unmonitored state maps -- PRTG never
  returns that string.
- Parse the historic-data `datetime` string explicitly instead of relying on
  `new Date()`, which rejects PRTG's European format ("04.12.2017 16:35:08")
  and resolves the others against the host time zone rather than PRTG's.
- Report a genuine 0% coverage as 0 rather than null.

Robustness:

- Build the PRTG date strings from Intl.DateTimeFormat.formatToParts in
  sensorHistory.js, sensorHistory.json and logs.json, so nothing depends on
  how a given ICU build separates the date from the time.
- Return null from offsetAt when the parts are not numeric, and propagate
  that, so `new Date(NaN).toISOString()` is unreachable.
- Strip everything outside the IANA character set from the interpolated time
  zone, so a quote in a custom value cannot inject into the request script.
- Clamp the Sensor History window to 30 days, so a tile following a longer
  dashboard timeframe returns the most recent 30 days instead of asking PRTG
  for a range it cannot serve within the response cap.

Conventions:

- Rename source types to unprefixed upstream terms (Probe, Group, Device,
  Sensor) per REVIEW.md. Display text is unchanged.
- Move scopes.json to defaultContent/, where the other 30 plugins and the
  authoring docs put it.
- Use a recursive CODEOWNERS pattern for the plugin directory.

Documentation:

- Reword the authentication notes. PRTG's manual documents
  `Authorization: Bearer`, but 26.3.122.1665 answers 401 "Unsupported
  authorization scheme" to that, to `Authorization: apitoken` and to
  `X-Api-Key`, leaving the apitoken query parameter as the only scheme that
  works.

Verified against PRTG 26.3.122.1665 with the account time zone at UTC+1.
`table.json` raw datetimes are confirmed UTC, so the log conversion is
unchanged. `datetime_raw` is not usable in historicdata.json: it is only
returned when `usecaption` is omitted, which collapses every channel into a
single unnamed column, and it carries the bucket end rather than its start.

PRTG still has no per-request override (Paessler confirm this), so there's no parameter for UTC. The plugin no longer depends on the zone, though. As of eed3b80 the time zone setting is gone. filter_dstart/filter_dend are sent widened by −12h/+14h, which covers every real UTC offset, and logs.js trims the results back to the exact timeframe using datetime_raw, which PRTG always reports as UTC. Sensor History does the same with Date Time(RAW) from historicdata.csv. The line this thread is pinned to hasn't changed, which is why GitHub doesn't show it as outdated. The value under it is new.

I think we should look to use the v2 API here... otherwise this will likely become out of date very quickly.

Important: The PRTG API v2 is not yet feature-complete. Most endpoints are stable and you can use them in production, with the exception of endpoints marked as experimental or deprecated. Experimental endpoints are subject to change, so use them with caution. For more information, see the section Endpoint maturity.

ℹ️ If you cannot achieve your objective with the PRTG API v2, you can try the PRTG API (v1). For more information, see the PRTG Manual: HTTP API.

Comment thread plugins/PRTG/v1/icon.svg
Comment thread plugins/PRTG/v1/metadata.json
PRTG's v1 API interprets `filter_dstart`/`filter_dend` in the time zone of
the account whose API key is in use and offers no UTC option, so the zone
has to be configured. Until now a wrong answer failed silently: Log and
Sensor History shifted by the difference, or looked empty on a short
timeframe, with nothing to point at the cause.

`getstatus.htm` reports the account's zone as a fixed offset in
`UserTimeZone`, which System Status already surfaces. Too coarse to
replace the setting — Sensor History spans 30 days and needs the daylight
saving transitions an IANA name carries — but enough to check it against.

Adds a hidden `timeZoneCheck` stream and a non-blocking Time zone step in
configValidation. Two things worth knowing about the comparison:

- It accepts the zone's current offset *or* its standard one. PRTG labels
  zones by standard offset in its own UI, so which of the two
  `UserTimeZone` carries is unknown. Accepting both still catches a zone
  picked on the wrong continent without crying wolf every summer.
- A `UserTimeZone` it cannot parse passes rather than warns — a PRTG
  version that words the field differently must not fail setup. A bad
  IANA name is compared as UTC, because that is what the request side
  falls back to sending.

The step returns one row on agreement and none on mismatch because
`errorOnEmptyResults` can only fail a step on empty. It is `required:
false` so a false positive cannot block anyone from connecting.

Answers the review question on whether this should target PRTG API v2.
Checked against the published API v2 OpenAPI specification: v2 has no log
endpoint, no arbitrary historic-data range, and no time zone endpoint, so
the Log and Sensor History streams and the setup time zone check could not
be built on it. What remains is marked experimental, and v2 is unavailable
on Hosted Monitor and off by default on existing installations.

Records the conditions under which a v2-based plugin becomes worth having,
as a new major version rather than a change to this one.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The API v1 time zone is a property of the PRTG account the key belongs to,
not of the request — Paessler document no per-request override. Cite that,
and note API v2 has no time zone endpoint either.

Because the zone follows the account, pointing the key at a dedicated PRTG
account set to UTC removes the problem entirely, daylight saving included.
That was not written down anywhere; add it to Setup, worded so it does not
read as contradicting the advice to pick a region rather than an offset.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The icon was the stacked "PRTG / NETWORK / MONITOR" lockup. Each text line
was only about 63px tall inside the 512 canvas, so at tile size the words
rendered around 4px tall and read as a smudge.

Drop the three wordmark paths and rescale the four gauge-arc paths, which
were already in the file, to fill the square. Keep the white plate: it is
the convention for the other 512-viewBox icons here, and the needle is
navy, so it would disappear on a dark tile without one.

The object streams fetched `count=50000` in a single request with
`paging: { mode: "none" }`. That is the stopgap 4aff6af called out on
NinjaOne — it works until an estate outgrows one response, then fails
whole rather than degrading, and it cannot be tuned per installation.

`table.json` takes `start` as a row offset alongside `count`, which maps
onto the platform's row-offset paging directly. Row counting reads back
through `payloadArraySize` on the same path as `pathToData`, so a short
page ends the run — no dependence on `treesize`, which is honest for the
object tables but a placeholder `1000000` for `content=messages`.

All six paged streams already sorted by `objid`. That matters more than it
looks: offset paging over an unstable order silently skips and repeats
rows.

`sensorChannels` keeps `mode: "none"`. A sensor's channel count is bounded
small and the endpoint has no stable sort to page over, so the machinery
would add risk for nothing — its `count=50000` is dropped in favour of
PRTG's own default. `logs` is left alone too: it is capped at 5,000
newest-first with no usable total, which is a different problem.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The "Why this plugin uses API v1" section was written to answer a review
question, so its accuracy is the whole point of it. Three claims did not
survive checking against the published OpenAPI specification:

- Object listing does not need one request per type. `GET
  /experimental/objects` returns probes, groups, devices, sensors and
  channels from one paged endpoint, and its `filter` takes `parentid`
  plus `children`/`descendants`/`ancestors`. 3,000 is a per-request page
  size with RFC 5988 `Link` headers, not a ceiling. This is better than
  API v1, not worse.
- Arbitrary historic ranges do exist, via `from`/`to` on
  `/experimental/timeseries/{id}`. That endpoint is deprecated and slated
  for removal, and neither form has an averaging control — which is the
  real objection, and a narrower one than "no arbitrary range".
- `/experimental/channels` is experimental but not deprecated. The
  `deprecated` markers in that block sit on its `filter` and `sort_by`
  parameters.

Drops the time zone row entirely. It listed the absence of a time zone
endpoint as an API v2 gap, when API v2 returns ISO 8601 in UTC throughout
and would remove this plugin's time zone setting altogether. Presenting
an advantage as a deficiency was the least defensible line in the
section, and the Known limitations note that echoed it is corrected too.

Reorders the three reasons to lead with deployment reach — no Hosted
Monitor, no clusters, administrator opt-in below 25.2.106 — because that
is the one that actually binds a single-base-URL low-code plugin, and
the endpoint table was carrying an argument it cannot support alone. Also
states Paessler's stated intent to retire API v1 eventually, rather than
leaving "no announced end of life" to be read as spin.

Names the tested build in the compatibility callout, and rewrites the
response-size limitation now that the object tables page.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Three unrelated bits of drift, none behavioural:

- `PRTG` and `Paessler` were added to the root `cspell.json`. AGENTS.md
  documents the per-plugin list as the place for product names the root
  list does not cover, and eleven plugins already do that, so they move
  to `plugins/PRTG/v1/cspell.json` and the root file returns to matching
  `main`.
- The CODEOWNERS entry was `/plugins/PRTG/`, the only one of 26 with
  leading and trailing slashes. Recursive ownership is arguably the
  better pattern, but it is a repo-wide question rather than a PRTG one,
  so match the surrounding `plugins/X/*` form instead of being the
  exception.
- The `edate` expression in `sensorHistory.json` declared `MAX` and
  `start` and used neither, copied from `sdate` where the 30-day clamp
  genuinely applies.

…f ending

table.json's start parameter returns the last page again once it runs past
the end, so row-offset paging never terminated. Page with
filter_objid=@above(<last objid>) instead, which returns nothing once no
rows remain. The scripts also rebuild status from status_raw, because the
status text varies by PRTG version.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…ates

PRTG reads date ranges in the API account's time zone. Log and Sensor
History now widen each request by 12 hours before and 14 hours after, then
trim the results using the UTC OLE _raw dates. Sensor History reads
historicdata.csv, the only form that carries both the channel names and
Date Time(RAW). This removes the time zone field, its save-time check and
the timeZoneCheck stream.

Feedback Response
@clarkd: local time zone, "no way to ask for a specific timezone?" PRTG really has no override, so the plugin no longer asks for the zone at all. Requests cover every possible offset and are trimmed by the UTC raw timestamps PRTG includes on every row.
@clarkd: use API v2 Covered in the README's Why this plugin uses API v1 section, checked against the OpenAPI spec. API v2 is unavailable on PRTG Hosted Monitor and off by default on existing installs. It has no log endpoint, and arbitrary historic ranges exist only on an endpoint Paessler have deprecated. What remains is marked experimental. The section lists the conditions for building a v2 plugin later as a new major version.
@clarkd: icon unreadable at small sizes Now the PRTG gauge mark alone (200b781).
CodeRabbit: timeZoneCheck single-object Moot, because the stream has been removed.
CodeRabbit: supported-version claim too broad The README names the tested build (26.3.122.1665) and says other API-key versions are expected to work. API v1 is Paessler's stable, non-deprecated API.
CodeRabbit: API v2 comparison inaccuracies Corrected in 26cb331.

The Sensors Needing Attention tables filtered only statusText != Up, so
deliberately paused sensors (codes 7, 8, 9, 12) were listed. Exclude
Paused as well on the overview, probe and group dashboards.

Sensors per Device grouped on the device display name, merging devices

and group the chart on it.
