Getting hp-snmp-agents on HP ProLiant DL360 on Lenny working [duplicate]

System load by HP-SNMP-Agents is high

After receiving our HP ProLiant DL360 I'd like to integrate the machine into our Munin system and thus enable ProLiant specific information to be exposed via SNMP.

I'm running Debian Lenny with kernel 2.6.26-2-vserver-amd64 . I've followed http://downloads.linux.hp.com/SDR/getting_started.html and the HP repository has been added to /etc/apt/sources.list.d/HP-ProLiantSupportPack.list .

Setting up Lenny SNMP itself is not a problem, I configure it to have a public v1 community string to read all data and it works. I install hp-snmp-agents and run hpsnmpconfig and it adds additional lines to the top of /etc/snmp/snmpd.conf :

dlmod cmaX /usr/lib64/libcmaX64.so

snmpd gets restarted.

Via lsof I can see that libcmaX64 was loaded and is used by snmpd, put I do not get any additional information out of snmp. I use snmpwalk -v 1 -c public ... and I can see many OIDs but I do not see the new ones I'd expect, most notably temperatures, fan speed and such.

The OIDs I'm expecting are e.g. 1.3.6.1.4.1.232.6.2.6.8.1.4.1 , this is from the existing munin plugins from http://exchange.munin-monitoring.org/plugins/snmp__hp_temp/version/1 .

This doesn't look particular bad for me, it's just informational I guess.

I've compared the walking OID output with and without the module and there's no difference in the OID served back at all. Are there any other prerequisites I'm missing?

I've also noticed that from the time I installed hp-snmp-agents it adds a lot of additional daemons and that my load suddenly jumps to 1. I've uninstalled the package for now. Is this expected behavior?

  1. I'm experiencing the same, my load also stays put at 1 after starting the agents. I've found a solution in this thread, which reduces the load back to at least 0.6:

    Also make sure you have different community strings for the various options. Otherwise you'll keep seeing 'error in subcontainer' messages in /var/log/net-snmpd.log

    Update: I'd asked about the same question before finding yours (just with a completely different title); System load by HP-SNMP-Agents is high You'll find the answer there. Quoting:

    In short, you'll want to stop the HP management agents with /etc/init.d/hp-snmp-agents stop. Edit the exclude line in /opt/hp/hp-snmp-agents/cma.conf from:

    exclude

    to

    exclude cmasm2d cpqriisd cmarackd

    Start your agents again with /etc/init.d/hp-snmp-agents start
