obnam Check

Obnam 1.0/1 gibt passenden Output für Nagios aus. Mit meinem Patch wird direkt Output für check_mk generiert und ein Local-Check kann sich auf folgende Zeilen beschränken:

#!/bin/sh
 
/usr/bin/obnam check_mk-last-backup-age 2>/dev/null ||
echo "2 obnam_backup - CRITICAL - System Error"
