SNMP running at very high CPU usage on RH 2.1

[TJ_16]

We are running RedHat AS 2.1 Update 4 on some DL580 G2s and DL380 G2/3s and I am seeing the snmpd spiking on CPU usage quite frequently.
We are running the HP management software (hpasm/hprsm) and I just got the newest ucd-snmp packages from the HP web site.

1. As we are just still fairly green with Linux, can someone explain SNMP to me?
2. Anyone else seeing this and have any suggestions?

Thanks,

SNMP
Simple
Network
Management
Protocol

Properly configued it lets the network administrator know if your box is working righ t and on the network.

Improperly configured it is a security risk and can be used to gain root priviledges or denial of service.

You may need to check with your network administrator and make sure too much information isn't being collected, or adjust the polling interval.

Run up2date on the box and make sure all patches are installed.

Hi TJ,
snmpd is the daemon that receives snmp traps (informations generated by this and other machines on the network) and that may take some actions depending on those informations, or simply report it.
I suggest that if you are not making any use of things like that,i.e., you have not configured snmpd to do it's job, you don't start snmpd anyway.

Well, I thought the HP management daemons used SNMP to report certain errors. We have done a little SNMP configuration, but if we don't absolutely need it, I would just as soon disable it...

Ok TJ,
If you are happy with the answerers and you don't need more help, please, don't forget to close the thread.

what do you mean happy with the answers??? I have got nothing out of any of the answers that even remotely helps me even start to diagnose my problem...
What would/could cause the snmpd daemon to run at very high CPU usage?

Thanks.

Ok TJ,
I thought you will not need to use snmpd and not to start it solves your problem. My mistake. Let's try to look for informations that may help you. Verify on /var/log/messages if there are any messages regarding snmpd. If you find any, please report to us.

Hi

Wanted to know what kind of server you running RedHat AS 2.1, we have Compaq/HP servers running 2.1 with CIM, the new version on Insight Manager has it's own SNMP rpm which replaces the RedHat SNMP rpm which in some cases are creating issues, you would want to check that also, we have decided not to install the SNMP from the insight manager.
