Check last HyperBackup for Synology (Synagios)

Nagios Plugin to check when the last Backup was done with HyperBackup

Preparation: The HyperBackup Logfile is required within the Nagios-chroot. As there is a limited access right on the original file we'll copy it:
1. copy "check_hyperbackup.sh" to /volume1/@appstore/Synagios/nagios-chroot/usr/lib/nagios/plugins/
2. make the script executable: chmod a+x /volume1/@appstore/Synagios/nagios-chroot/usr/lib/nagios/plugins/check_hyperbackup.sh
3. copy "synobackuplog.sh" to /volume1/@appstore/Synagios/nagios-chroot/bin/
4. make the script executable: chmod a+x /volume1/@appstore/Synagios/nagios-chroot/bin/synobackuplog.sh
5. create cron-job which runs every hour in /etc/crontab (globally, not in nagios-chroot!):
5 * * * * root /volume1/@appstore/Synagios/nagios-chroot/bin/synobackuplog.sh
6. run the script one time: sudo ./volume1/@appstore/Synagios/nagios-chroot/bin/synobackuplog.sh

Tested on Synology DS116 using Synagios

Usage: ./check_hyperbackup.sh $ARG1$ $ARG2$

$ARG1$ = Warning-Level
$ARG2$ = Critical-Level
