Nice check! Must have!

It’s very useful check which must be turned on for every server!

PS: but small changes for check_all_diskstat.sh can be applied as soon it not returning a correct exit status for nagios notification.

I make some changes which can help somebody else:
###################
#!/bin/bash
EXITCODE=0
CHK=/usr/lib/nagios/plugins/check_diskstat.sh
WARN=${1:-“300,10000,10000”}
CRIT=${2:-“400,20000,20000”}

for DEVICE in `ls /sys/block`; do
if [ -L /sys/block/$DEVICE/device ]; then
DEVNAME=$(echo /dev/$DEVICE | sed ‘s#!#/#g’)
echo -n “$DEVNAME: ”
OUTPUT=”`$CHK -d $DEVICE -w $WARN -c $CRIT`”
STATUS=$?
if [ “$EXITCODE” -le “$STATUS” ]; then
EXITCODE=$STATUS;
fi
echo $OUTPUT | sed “s#=#_$DEVNAME=#g”
fi
done
exit $EXITCODE
