Ganglia gmetric Scripts

Script for monitoring SAN disk activity (Avg % of total disk busy). 


Eg: for monitoring the disk activity on Controller 8 (c8)

while true;

do

iostat -xcn 2 15 |grep c8|grep -v b|awk {'print $10'}>/tmp/iostat

DTot=`iostat-en|grep c8|wc -l` #Total Number of disk in Controller c8

tail -$DTot  /tmp/iostat >/tmp/iostat.new

Per=`awk 'BEGIN{total=0}{total += $1} END{print total}' /tmp/iostat.new`

Aper=`echo $Per / $DTot |bc`

/usr/local/bin/gmetric --name Avarage_SAN_usage_of_168_disks  --value $Aper --type int32 --unit Avg_%
