Radarr (beta)¶
Whether Radarr still finds and imports movies: health errors, failing download clients and indexers, errors in the download queue, 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 |
|---|---|---|
| 7878 | TCP | API (HTTP, default) |
| 443 | TCP | Only with the https scheme behind a reverse proxy |
The failure worth watching: a download client or an indexer that quietly stopped. Radarr keeps running and its page opens, but nothing is grabbed or imported any more; the only trace is the red banner of its System → Status page, which DumbMonit reads as it is.
What it watches¶
All metrics are prefixed dumbmonit_radarr_.
| 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 |
queue_total, queue_unknown |
items in the download queue, and those Radarr cannot match to its library | |
queue_has_errors, queue_has_warnings |
1 when at least one queue item has an error (failed download, import blocked) or a warning | |
disk_used_percent, disk_free_bytes |
each disk Radarr reports (root folders, download folder), at most 32 | path |
scrape_errors |
calls that failed on the last probe |
The built-in rules that apply: Radarr health error, Radarr queue has errors, Radarr disk almost full, Radarr update available, plus Monitor unreachable.
Read the API key in Radarr¶
-
In Radarr, open Settings → General → Security and copy the API Key.
-
In DumbMonit, enter Radarr's address and paste the key.
Warning
A Radarr API key cannot be limited to reading: keep it only in DumbMonit, which sends GET requests and nothing else.
Credentials¶
| Credential | Fields |
