[Nagiosplug-help] Nagios SNMP help for CPU utilization

[Patrick Proy]

That's easy : just store the counter values, make a substraction and divide
by all the values. You will need to write a script for this... 
Why do you need instant CPU BTW ?

Hi Patrick,
  Thanks for your quick response. I think I can use snmpget (in linux)
instead and add that command in a shell script and call the script in
Nagios. But do you know how can I convert the counter values (ssCpuRawUser,
ssCpuRawNice, ssCpuRawSystem, ssCpuRawIdle) to the percentage of CPU
utilization?

Thanks,
Amitabh

Hi,

If you want real-time value, you must get the counters (ssCpuRawUser,
ssCpuRawNice, ssCpuRawSystem, ssCpuRawIdle) instead.
But you won't be able to use check_snmp....

Hi,
  I am using Nagios snmp plugin (NetSNMP) for monitoring the cpu usage of
remote servers (Running Red Hat Linux). The output I am getting is the
average value  instead of the real-time value (i.e. output of the top
command). I am using the following command. 
  I would appreciate if someone can help me out on this.

./check_snmp -H <host_name> -C <community_name> -o
.1.3.6.1.4.1.2021.11.9.0,.1.3.6.1.4.1.2021.11.10.0,.1.3.6.1.4.1.2021.11.11.0

Thanks,
