Here is a script I write to monitor and graph disk i/o on a linux system;

Code: Select all

#!/bin/bash

STATE_OK=0
STATE_WARNING=1
STATE_CRITICAL=2
STATE_UNKNOWN=3

device=$1

tps=`iostat | grep $device | awk '{print $2}'`
blkWrite=`iostat | grep $device | awk '{print $4}'`

echo "Status Ok: Device $device - TPS=$tps, Blk_wrtn/s=$blkWrite | TPS=$tps; Blk_wrtn/s=$blkWrite"
exit $STATE_OK

Works for my needs. I am not alerting on it, just trending.
