Red Hat Bugzilla – Bug 869716
Availability check change is not automatically picked up
Last modified: 2013-09-11 07:00:17 EDT
Description of problem:
When Availability check is changed, for instance from enabled to disabled, this change is not picked up by the agent and availability is still checked and server status changed depending on it's real state.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Import JBoss instance;
2. Navigate to Monitor -> Schedule (for that server instance) and disable Availability check;
3. After some time (at least 2 minutes if Availability check was initially set to 1 minute), stop the JBoss instance;
4. Execute "avail --force" on the JON Agent command line;
5. Check the status of the JBoss server;
The status of the JBoss instance changes to DOWN in JON UI.
JBoss stays UP because it picks up the status of its parent resource (platform) as explained in .
The change in Availability check will be propagated after the agent is restarted with "--purgedata" option.
The impact of this issue can be pretty bad. It prevents the update of a resource's availability check interval from being modified, enabled, or disabled. The workaround is to force an inventory sync but this is a manual process. One can either execute agent command:
Or restart the agent with the --purgedata command-line argument or delete the agent's inventory.dat file.
All workarounds are not really ideal considering they all require knowledge of this bug before updating availability metric collection schedules for inventoried resources.
I see no reason not to CP this to 3.1.2:

Set availability schedule data if present in ResourceMeasurementScheduleRequest
Cherry pick of master commit: 257e056801c29bc241b7c292008326be14faffb9
Moving to ON_QA as new build available to test with:
Verified on JON 3.1.2 ER5.
Followed the steps and verified that after avail --force at agent command line, the JBoss instance remains UP in JON UI.
