SNMP & MIBs

[Phil Daws_2]

Hi:

Without installing NNM is it possible to gain access to CPU utalisation, memory stats using SNMP? I see SNMPD is installed but I have done a snmpwalk on the host and it only reports network statistic information.

Hi,

If you have glance installed then you can get the real time statastics. Or if you have measureware running then you can extract the perfromance data by perfview.

hey,

If u r really looking for a performance analysis tool, the use top, sar, glance, perfview ..etc.

For processor specific tool, u can use 'PRM'

Hi Phil,

As far as your question is concerned, there are some default OIDs available with HP's snmp agent. Check the tree

.private.enterprises.hp.nm.system.general

There are couple of downtrees. You might be interested in browsing through processes tree.
You may have to do an snmpget on these OIDs.

For ex., the OID of userCPU is

.1.3.6.1.4.1.11.2.3.1.1.13

Do an snmpget on this, you will get userCPU. But this gives only the time. You will not get a nice value like 50%.

Hi.

Yes, I have used glance, sar, top, vmstat etc etc ... But I want to pull off some simple stats via SNMP as I have 80 boxes to monitor. I have tried snmpget x.x.x.x community .1.3.6.1.4.1.11.2.3.1.1.13 but it returns :

Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: enterprises.11.2.3.1.1.13

What MIB is required on the machine?

Hi,

i get the following 'roots':

system, interfaces, at, ip, icmp, tcp, udp, transmission, snmp, enterprises and .iso

what's enterprises and .iso? :)

enterprises shows some info on lvols... and a lot of numbers. it must be there, somewhere...

Hi,

digging a bit deeper:

on my machine (hp visualize c240)

enterprises.11.2.3.1.4.1.0 - number of processes

enterprises.11.2.3.1.4.2.1.1.x - id of process

and so on, with the processes.

I didn't catch any memory / CPU info (yet) but I am still digging.

What you need to do is get MRTG.

http://people.ee.ethz.ch/~oetiker/webtools/mrtg/mrtg.html

It will poll the CPU every 5 minutes and draw you a pretty graph. It can do the calculations to give you the answer in percent. Can also track your free memory or any other MIB that is available on your PC.

Price is right. It's free. Runs on UNIX or WindowsNT.

.iso.org.dod.internet.private.enterprises.hp.nm.system.general.computerSystem.computerSystemFreeMemory
is
.1.3.6.1.4.1.11.2.3.1.1.7

.iso.org.dod.internet.private.enterprises.hp.nm.system.general.computerSystem.computerSystemIdleCPU
is
.1.3.6.1.4.1.11.2.3.1.1.15

Hi Phil, (Didn't you use to work at CW for HPO? I'm still there!)

I use MRTG on my test servers at home and it works a treat.

Cheers
