A Prometheus exporter for Borg backups.
It provides the following metrics:
| Name | Description | Type |
|---|---|---|
| borg_backups_total | Total number of Borg backups | Gauge |
| borg_last_backup_timestamp | Timestamp of the last backup | Gauge |
Borg exporter runs as a Python binary managed by Systemd. It provides a command to bootstrap into a simple systemd service.
To install the binary from Github:
curl -L https://github.com/danihodovic/borg-exporter/releases/download/latest/borg-exporter -o ./borg-exporter
chmod +x borg-exporter
sudo mv ./borg-exporter /usr/local/bin/
sudo borg-exporter enable-systemd
Alerting rules can be found here. By default Prometheus sends an alert if a backup hasn't been issued in 24h5m.
You can find the generated Grafana dashboard here and it can be imported directly into the Grafana UI.
It's also available in Grafana's Dashboard Library.
