Prowlarr (beta)¶
Whether Prowlarr still serves its indexers: health errors, indexers disabled after failures, disk space and updates.
Beta
Written from the vendor's API documentation and tested against realistic recorded-style responses, not yet against a live instance. Tell us what you see.
Network ports to open¶
From the DumbMonit server (or its relay agent) to the device:
| Port | Protocol | Purpose |
|---|---|---|
| 9696 | TCP | API (HTTP, default) |
| 443 | TCP | Only with the https scheme behind a reverse proxy |
The failure worth watching: an indexer that is disabled and forgotten. After a few failures Prowlarr disables an indexer for hours, then days; Sonarr, Radarr and Lidarr keep searching through the others and nothing says that releases are missing.
What it watches¶
All metrics are prefixed dumbmonit_prowlarr_.
| Metric | What | Labels |
|---|---|---|
version_info |
value 1 | version |
update_available |
1 when a newer release exists (absent when the update list is unavailable) | latest_version |
health_errors, health_warnings |
checks of the System → Status page that report an error or a warning | |
health_issue |
value 1 for each error or warning, at most 32 | source, level |
indexers_disabled |
indexers still disabled after repeated failures | |
disk_used_percent, disk_free_bytes |
each disk Prowlarr reports (root folders, download folder), at most 32 | path |
scrape_errors |
calls that failed on the last probe |
The built-in rules that apply: Prowlarr health error, Prowlarr indexers disabled, Prowlarr disk almost full, Prowlarr update available, plus Monitor unreachable.
Read the API key in Prowlarr¶
-
In Prowlarr, open Settings → General → Security and copy the API Key.
-
In DumbMonit, enter Prowlarr's address and paste the key.
Warning
A Prowlarr API key cannot be limited to reading: keep it only in DumbMonit, which sends GET requests and nothing else.
Credentials¶
| Credential | Fields |
|---|---|
| API key | Sent in the X-Api-Key header. |
