HP SNMP Agents on Citrix XenServer 5.6

[Andrew_271]

I am having a major issue with the HP SNMP Agents bringing one of my two XenServers to its knees. The agents appeared to work OK on the older version of XenServer (5.5). After upgrading to 5.6, one of the servers constantly freezes until disabling the CMAHOSTD process.

I am running XenServer on 2 identical ProLiant DL580 G5's. Each has 16 cores and 64 gigs of ram.

With CMAHOSTD running, every 10-15 seconds the whole system pauses for a few seconds, not even responding to command-line keystrokes, then bounces back. While monitoring the TOP command in linux, CMAHOSTD jumps to 90%+ CPU usage briefly during this freezing. As soon as I disabled CMAHOSTD, the problem went away.

I originally upgraded XenServer on both servers. After having the problem, I rebuilt the server from scratch (no upgrade) and the problem continued.

The older version of the agents (from last year) with xenserver 5.5 worked fine on both servers.

Any ideas? Thanks.

I attached a screenshot of the TOP command.

Hi Andrew
sorry to bother you, but so far I have tried to configure the SNMP agents for a 5.5 pool with no success.
Could you please tell me how you changed the .conf file so it all worked out?
I know you are looking for an answer in here but so far mi understanding of the agents is not good enough to make them work.
Thanks in advance for your help.

Hi Andrew.

In the instructions you have on your site theres a file folder named /home/agents which contents is not specified.
Where do I find those files ?
Thanks for your help in advance.

1 mv hp-snmp-agents-xs-8.2.5-7 newname
2 remove the line #!/bin/sh at the top of the Script
3 sh newname
Voilá there're the RPMs

Now installiert the rpm's in order, as described on my site.

The important thing about that whole stuff...
DO NOT INSTALL THE IPMI RPM FROM HP,
INSTEAD INSTALL OPEN-IPMI out of centos-base repo.
