AS400 OS400 iSeries SNMP strings MRTG Graphs

by

AS400 performance graphing with MRTG can be a tricky thing. Once you have a public read only SNMP string defined and you have enabled SNMP on the iSeries you can test using snmpwalk from the linux server you plan on generating the MRTG graphs from.

cpu-day
cpu-month
dasd-percent-day
dasd-percent-year
dasd-raw-yeart
memory-used
nic-month
users-day
users-month

 

This is an example snmpwalk command for an as400

snmpwalk -v 2c -c YOURSNMPSTRING 10.0.0.10

Once the snmpwalk returns the SNMP information we are ready to poll it with MRTG and make some graphs.  The as400 will OFTEN time out and not complete a full SNMP return. I don’t know why this is. This is with very large systems as small alike. This is not the post to teach MRTG, but this is the spot to find the strings and the math I used to generate the graphs for our AS400s. Below are the keys to generating the MRTG graphs for your AS400. CPU, Users, RAM, ASP and others..
