Description Larry O'Leary 2015-04-17 19:55:38 UTC

Description of problem:
BZ 1147098 introduced a fix for loss of raw metrics during metric storage failure by adding a metric queue on the server-side. This fix included adding a new property to control/configure how large/small the metric queue could be. The property is QueueAvailableCapacity and has been added to rhq-server plug-in.

This work was done and committed to release/jon3.3.x as c9cd10cf0f541fe48cba03c03ce8fc1049b34f3f.

This BZ represents the plug-in portion which exposes the new configuration option in the JBoss ON UI via the RHQ Server resource's configuration page. The dependent BZ 1147098 represents the core server changes to support the actual fix.

Version-Release number of selected component (if applicable):
3.3.2

Comment 1 Michael Burman 2015-04-18 20:40:32 UTC

The queue size itself is not configurable actually (this is a bit trickier to implement as the queue size can't be changed on the fly without first emptying it).

The patch itself only gives the ability to monitor the size. If the queue size must be modified also, then changes are required to the JON itself.

Comment 2 Larry O'Leary 2015-04-20 13:51:17 UTC

As indicated in comment 1, the description provided in this BZ is incorrect. QueueAvailableCapacity is a metric. It is not a configuration option.

Comment 4 Filip Brychta 2015-06-17 14:33:01 UTC

Verified that QueueAvailableCapacity metric is visible and correct value (200 000) is displayed.
