SNMPDM

[Nobody's Hero]

I am running 'OpenMail' on a K580 running 10.20. I notice that, very often, the snmpd daemon is running at a high cpu rate for a long time, then it drops off. I know what snmp stands for, but can someone explain what it is used for and why it may be getting a tun of cpu time?

Thanks,
Bob

Hi,

When you see that again, run netstat on your system:

# netstat -f inet | grep -i snmp

This will tell you who is connecting to your snmpd daemon over the network.

Also, you may wish to run lsof as well. It will tell you which are the files being opened by the process etc. during the time of heavy CPU usage.

# lsof | grep -i snmp

Hope this helps. Regards.

Hi Robert:

'snmpd' is actually a script (an rc script) which invokes /usr/sbin/snmpdm (the master agent of SNMP daemon/process) with command line arguments. You will get a better idea from:

# man snmpd

Also I could find the patch - PHSS_26137 (s700_800 10.20 OV EMANATE14.2 Agent Consolidated Patch) which has fix for a couple of snpmd issues including CPU utilization > 90%.

HTH,
