    Restic log exporter

    This exporter parses restic's logs (either from a logfile or the systemd journal) and exports metrics from the last backup run.

    It is ased on this blog article and adapted to work with current restic versions (tested with 0.16.3).

    Usage

    Example usage with systemd timer or cronjob (requires "sponge" binary from i.e. the "moreutils" debian package):

    restic-log-exporter.sh | sponge /var/lib/prometheus/node-exporter/restic-backup.prom

    Example output:

    restic_backup_failure{unit="restic-all.service",timestamp="1663227870"} 0
restic_duration_seconds{unit="restic-all.service",action="total"} 1122
restic_last_successful_backup{unit="restic-all.service"} 1663227870
restic_repo_dirs{unit="restic-all.service",state="changed"} 1073
restic_repo_dirs{unit="restic-all.service",state="new"} 2
restic_repo_dirs{unit="restic-all.service",state="unmodified"} 104334

restic_repo_size_bytes{unit="restic-all.service",state="total"} 266086108889

    Todo

    • Better deal with failed backups
    • Add snapshot id (snapshot 30b9d571 saved)
    • Add restic backup duration
    • Rewrite in Python :)
