MisterX Tech

THIS IS LEGACY I HAVE REPLACED IT. I am leaving this up for archival purposes as it does still work just not as accurately as I would like.
OS: CentOS 5.4
Arch : x86_64
Version : 0.1a
Required Packages : netsnmpd, sysstat
snmpd conf addition:
exec .1.3.6.1.4.1.2021.40 SARDISKIO /usr/bin/mrtg_diskio
Client Script Used:
<script>
#!/bin/bash
#V 0.1b MisterX Dec 9th 2009
# Replace md0-md3 with the drives you want to watch
#OUTPUT example for first Drive :
#1.3.6.1.4.1.2021.40.101.1 tps
#1.3.6.1.4.1.2021.40.101.2 kB_read/s
#1.3.6.1.4.1.2021.40.1.1.3 kB_wrtn/s
#1.3.6.1.4.1.2021.40.101.4 kB_read
#1.3.6.1.4.1.2021.40.101.5 kB_wrtn
# and so on for each additional Drive. A snmpwalk -v2c -On -c $community $host 1.3.6.1.4.1.2021.40.101 will show
#you the full list for all drives.
