it works

no Perf data and the plugin shows not very accurate info…

But it works like a charm… I’ve edited myself for my needs:

if [ $RES = 0 ]; then
UPTDAY=$(expr $UPTMIN / 60 / 24 )
UPTMINT=$(( $UPTDAY * 1440 ))
UPTMINM=$(( $UPTMIN – $UPTMINT ))
UPTMINH=$(expr $UPTMINM / 60 )
UPTMINHM=$(( $UPTMINH * 60 ))
UPTMINHMS=$(( $UPTMINM – $UPTMINHM ))

if [ $UPTMIN -lt $CRIT ]; then
echo CRITICAL: Systemuptime $UPTDAY Days $UPTMINH Hours $UPTMINHMS Mins’|Uptime=’$UPTMIN’m;’$WARN’;’$CRIT’;0;0′
exit 2
fi

if [ $UPTMIN -lt $WARN ]; then
echo OK: Systemuptime $UPTDAY Days $UPTMINH Hours $UPTMINHMS Mins’|Uptime=’$UPTMIN’m;’$WARN’;’$CRIT’;0;0′
exit 0
fi

if [ $UPTMIN -ge $WARN ]; then
echo WARNING: Systemuptime $UPTDAY Days $UPTMINH Hours $UPTMINHMS Mins’|Uptime=’$UPTMIN’m;’$WARN’;’$CRIT’;0;0′
exit 1
fi

fi
