I am trying to find a way to get CPU performance data via SNMP and then use MRTG or openview to graph it. I've tried to find MID's that have this but no luck yet. Does anyone know it? All I want is CPU BUSY or something like that.
The server is a HP Proliant RX2660 running V8.3.
If anyone has any ideas that would be much appreciated.
Cheers,
Wayne

Re: Monitoring CPU stats with SNMP & MRTG or openview
I did not know that Vms was available on Proliant :-)
What is Cpu busy ? busy at 100% avec 2 processes in COM on a GS1280, or with 45 processes in COM on an Alpha 1000 ?
It is possible to graph Cpu performance, one example, among many possibilities, hyperspi++
http://pi-net.dyndns.org/hyperspi++
Just click on Cpu and remove anything else.
I do not know how to do this via Snmp, sorry.

SolutionWe use Cricket/RRDtool for the same job. You need to tell MRTG to query the hrProcessorLoad value (a percentage), 1.3.6.1.2.1.25.3.3.1.2.x, where x is the deviceID as reported by hrDeviceDescr (1.3.6.1.2.1.25.3.2.1.3).
I have had this working on Cricket for the past few weeks but have come across a problem of my own. We have two 4 processor systems in a cluster, however the SNMP process only seems to report on 3 of the processors on both systems:
bash# snmpwalk -v 2c -c
HOST-RESOURCES-MIB::hrDeviceDescr.1 = STRING: CPU 00 AlphaServer ES45 Model 2
HOST-RESOURCES-MIB::hrDeviceDescr.2 = STRING: CPU 01 AlphaServer ES45 Model 2
HOST-RESOURCES-MIB::hrDeviceDescr.3 = STRING: CPU 02 AlphaServer ES45 Model 2
If anyone can shed any light as to why CPU 03 isn't listed, please let me know!

Re: Monitoring CPU stats with SNMP & MRTG or openview
It seems though that I have the same problem with our dual processor, CPU 01 won't show.
MOO>snmp_request moo "public" get 1.3.6.1.2.1.25.3.2.1.3.1
1.3.6.1.2.1.25.3.2.1.3.1 = CPU 00 HP rx2660 (1.59GHz/9.0MB)
MOO>snmp_request moo "public" get 1.3.6.1.2.1.25.3.2.1.3.2
- no such name - returned for variable 1
When a walk is performed, it misses the .2 altogether. However it appears to show a correct value for hrProcessorLoad.
MOO>snmp_request moo "public" get 1.3.6.1.2.1.25.3.3.1.2.1
1.3.6.1.2.1.25.3.3.1.2.1 = 2
MOO>snmp_request moo "public" get 1.3.6.1.2.1.25.3.3.1.2.2
1.3.6.1.2.1.25.3.3.1.2.2 = 2
Anyway, I will just have to wait and see how the graph appears after the daily backup.
Thanks again,
Wayne

Re: Monitoring CPU stats with SNMP & MRTG or openview
Regarding the missing entry for CPU 01 (or CPU 03 in my case), I am willing to bet that over time your CPU 01 processor load will graph exactly the same figures as your CPU 00 processor load.
On our systems, the hrProcessorLoad OID for what should be CPU 03 responds with data but it's an exact copy of the data for CPU 02.... let me know what you find!

Re: Monitoring CPU stats with SNMP & MRTG or openview
http://www.mnlab.cs.depaul.edu/cgi-bin/sbrowser.cgi?HOST=&OID=HOST-RESOURCES-MIB!hrProcessorLoad (but my test suggest that it's the average of several minutes) and http://www.mnlab.cs.depaul.edu/cgi-bin/sbrowser.cgi?HOST=&OID=HOST-RESOURCES-MIB!hrProcessorLoad&ACTION=WELCOME is a very good walk trhu starting point.
