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.
Network ports to open
Section titled “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
Section titled “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.
