Monitoring

Monitoring if zfs-autobackup succeeds

On completion, zfs-autobackup returns an exit code:

• 0: Everything went fine, no important errors.
• x: Snapshotting was ok, but there are x datasets that aborted with a fatal error.
• 255: Wrong options or other major failure, probably nothing succeeded.

Output

Without --verbose or --debug, zfs-autobackup only echos (zfs) errors and warnings to stderr. Complete silence means everything is fine.

So if you stick it in a crontab it should only mail you if something is wrong.

If it detects a tty it will output progress updates to stdout.

Monitoring example with Zabbix-jobs

You can monitor backups by using my zabbix-jobs script. (https://github.com/psy0rz/stuff/tree/master/zabbix-jobs)

Put this command directly after the zfs_backup command in your cronjob:

zabbix-job-status backup_smartos01_fs1 daily $?

This will update the zabbix server with the exit code and will also alert you if the job didn't run for more than 2 days.
