Nagios Check for Systemd Failed Units

Just a short bash script to check for faulty systemd units to avoid 107 lines of Python...


if [ -f /bin/systemctl ]; then failed=$(/bin/systemctl --failed --no-legend) failed=${failed/ */} # Strip everything after first space failed=${failed/.service/} # Strip .service suffix

if [ "$failed" != "" ]; then echo "Failed units: $failed" exit 1 else echo "No failed units." exit 0 fi else echo "No systemd. Nothing was checked!" exit 0 fi
