Expected results:
I don't think we should be looking for snmp in rhq build.

Additional info:

Comment 1 Lukas Krejci 2010-12-01 20:31:01 UTC

The Apache SNMP module is a third-party software that we bundle only with JON. That doesn't mean though that the user can't obtain it separately from the JON subscription so imho we shouldn't just switch this off altogether in RHQ.

That said, the commit ae99b5bc0bf42909308a9d1efc09cee77d06ffc1 lowered the logging level of this error message to DEBUG so it shouldn't appear in the logs unless the logging configuration is altered.

Comment 2 Sunil Kondkar 2010-12-03 10:39:44 UTC

Tested on jon241 build#34.
The agent log did not show the exception. This will be verified again on latest rhq build.

Comment 3 Sunil Kondkar 2010-12-07 10:41:18 UTC

Verified on rhq-server-3.0.1-SNAPSHOT build# 450

Installed rhq-server and rhq-agent. Started and discovered httpd.
The agent log did not show the exception. Marking this as verified.

Bookkeeping - closing bug - fixed in recent release.
