Know when something goes wrong
HealthCheck watches your Nextcloud admin log and notifies entitled admins when new ERROR or FATAL lines appear — email, Slack, webhook, or in-app. Digests, mutes, and safe defaults keep alert volume under control. Web free (AGPL).
What the app does
Stop checking logs over SSH or wiring fragile cron scripts. HealthCheck gives admins a health dashboard and alerts when the instance logs new errors — without sending raw log text by default.
Health dashboard
Jobs, disk, HTTPS, and update checks at a glance — honest when HealthCheck cannot watch (unsupported log backend).
Browse & search logs
Read the newest part, search literally, copy lines, and browse rotated copies — system admins only for destructive actions.
Survives logrotate
Durable byte cursor with rotate/truncate recovery — no missed alerts after nightly rotation.
Mute noise
App-id and regex mutes; HealthCheck itself is muted by default so its own lines do not spam you.
Safe by default
Alerts use aggregates only — no raw log excerpts unless a system admin opts in with confirmation.
Role-based access
Nextcloud admins and delegated app admins — not open to every user on the instance.
Clear limits
File-based logging only; one shared log file per cluster; no SIEM export or auto-remediation in V1.
