Bug 785802

+++ This bug was initially created as a clone of Bug #785026 +++

Description of problem:
If event logging is enabled but native support is disabled, events do not get processed.

A pure Java alternative should be provided in cases where native support is unavailable or the user should be warned that although event logging is enabled for a resource, it will not be active due to native support being disabled.

Version-Release number of selected component (if applicable):
4.3

How reproducible:
Always

Steps to Reproduce:
1. Enable event logging for an AS resource or RHQ Agent
2. Confirm events are being logged
3. Restart agent with the --nonative command-line option
  
Actual results:
No events are logged once the agent is started with --nonative and the agent log contains no information indicating that event logging is failing

Expected results:
Event logging should continue to work

Additional info:
Ian's response from rhq-devel https://fedorahosted.org/pipermail/rhq-devel/2012-January/001434.html confirms this issue exists and suggests that it might be possible to implement a pure Java option.

Raising the sev on this to medium. We really should be logging a warning. It would also be nice if we threw an exception in the plugins if a user tried to enable log events when native support is disabled in the Agent.

But I think getting log events to work w/out SIGAR is low priority, since we support SIGAR on all the major platforms.

per 12/30/2012 BZ triage meeting mfoley, ccrouch, loleary, asantos

we are splitting this BZ into 2 ...

1) we are reducing the scope of this BZ.  providing customer feedback *is* the new reduced scope of this BZ ... and this is being targetted for 3.01.

2) i will be cloning a 2nd BZ as an RFE for the pure java alternative
