How to troubleshoot CIM agents

[Jesper Rune Larsen]

Hi all,

We are using NetIQ AppManager to manage our servers. On some servers the CIM agent fails to deliver SNMP data to AppManager. When I test the snmp configuration using 'snmputil', I get 'errorStatus=2, errorIndex=1'.
I've tried to update the CIM agent on one machine to 7.0, but that didn't help at all.

I'm desperate to get some help on this issue.
Please help me.

Best regards,
Jesper

Unfortunately, SNMP is not a guaranteed delivery mechanism which is why most management applications do polling in addition to expecting to receive events.

Something you might look into is in addition to having your AppManager system be the trap destination, use localhost. I don't know if AppManager has a local trap receiver like OpenView Operations does, but if it does, that could be added insurance.

The AppManager agents work locally by querying CIM using get/getnext/walk (I assume).
I can query other information on the machines through snmp, just not CIM information.

I did some further investigation....
I issued the following command "snmputil walk %agentname% public .1.3.6.1.4.1".
The result was interesting:
On servers where CIM works, the output is 800-1200kb, but on servers where it doesn't work it seems to run endlessly.
It gets 'stuck' in some LANMAN info. Here's an example:

Variable = .iso.org.dod.internet.private.enterprises.lanmanager.lanmgr-2.domain.domServerTable.domServerEntry.domServerName.15.87.83.49.84.79.49.83.69.65.82.67.72.84.83.227370
Value = Null value

The last number in the OID just keeps on increasing. This leads me to think that there is some sort of corruption in the SNMP repository??? Am I way off target here?

Hi Jesper,

I looked at AppManager 4 and the CIM Knowledge Module several years back and then some of the supplied Knowledge Scripts didn't have the latest CIM agent MIB info. (such as Power Supply Fault Tolerance) until after NetIQ supplied a patch. I suspect that your Knowledge Scripts and the the IM agent have got out-of-sync in relation to MIB info. they are attempting to pull back.

From memory the AppManager agent does SNMP gets and a separate async agent had the ability to receive traps though with AppManager 4 there was no ability to register/compile MIBs so that you manually had to add OIDs. I never tried this and I don't know if this has changed with newer AppManager releases.

I used a combination of SNMP tools from http://www.ncomtech.com/download.htm, a MIB walker from mg-soft and the appropriate MIBS from Compaq/HP to work through.

Sorry I can't be more specific.

HTH,

Brian
