system load average via snmp?

robert lojek_1 — Thu, 04 Apr 2002 19:05:55 GMT

I've been trying like the devil to get load average information from the HPUX 11.00 built-in SNMP agent (running on an L-1000), but I can't figure out which OID represents load, if any. We pointed our NNM X-based snmp-walking-utility at the machine, which at least translates the OIDs to text, then grep'd for "load", etc.--nothing.

This is standard fare under net-snmp (ucd-snmp) under ...private.enterprises, but HPUX's snmp agents' 4000-lines+ don't seem to contain the elusive load average numbers (1,5,15-minute).

Can I get load from the stock setup?

If not, what have others done? I'm not interested in workarounds, sar, etc., I'm trying to scale the tool we already have in place to gather this information.

Thanks for any help!

Hi Rob,

You can use snmpwalk/get to get the system load.

There are some good metrics under the tree

.iso.org.dod.internet.private.enterprises.hp.nm.system.general.computerSystem

If you are looking at the load, the following are the oids.

load average for 1 min * 100

.1.3.6.1.4.1.11.2.3.1.1.3

For 5 min

.1.3.6.1.4.1.11.2.3.1.1.4

For 15 min

.1.3.6.1.4.1.11.2.3.1.1.4

It will help you a lot if you have any snmpbrowsers or you can use snmpwalk and get all the possible values.

look for sysUpTime, use the grep -i option also.

Sri--
thanks for the note! I haven't tried your suggestion yet, since I just got finished building/installing net-snmp (4.2.4.pre3) (using:

binutils 2.9.1 binutils
gcc 2.95.2 gcc

packages), which compiled/installed without fanfare. It seems to be running stable, and it gives me the familiar
.1.3.6.1.4.1.2021.10.1.3.[1-3] OIDs that I've grown to love on our linux boxes. (no more HPUX one-offs).

I'm going to try your suggestion, but looks like net-snmp might be a good alternative, too.

thanks!
