Description John Mazzitelli 2009-08-13 11:49:00 EDT

the agent will send avail reports every 5 minutes. that means its possible that we won't know a resource went down for 5 minutes

we need the agent/plugin container to check avail faster (say, every 2 minutes or 1 minutes) but only if something changed (i.e. the repot has more than just the platform) should we send it up. If nothing changed, and we've crossed the 5 min threshold, then we should send up the report (even if its just got the platform)

this allows us to notify the server when something went up or down faster (every2 min? 1min? configurable?) but yet still let the server know we are alive every 5 minutes (we could then even increase that to every 10 or 15 minutes - the current quiet time on the server is 15 mins for agent backfill)

This bug was previously known as http://jira.rhq-project.org/browse/RHQ-2347

Comment 2 wes hayutin 2010-02-16 12:08:38 EST

mass add of key word FutureFeature to help track

Comment 3 Joseph Marques 2010-11-17 11:58:29 EST

I think we should implement this instead: https://bugzilla.redhat.com/show_bug.cgi?id=617648

Comment 4 Jay Shaughnessy 2012-02-28 14:53:44 EST

This has basically been implemented in the jshaughn/avail branch.  The
agent now performs avail checking at 30 second intervals, we provide
for resource-granular collection intervals (with server=1m, service=5m
defaults) and we do a better job of distributing checks to better avoid
peaks and valleys of avail processing.  And backfill has been dropped to
5 minutes.

See:

For more on planned avail changes.

Comment 5 Jay Shaughnessy 2012-03-30 16:39:47 EDT

This is in master.

Comment 6 Heiko W. Rupp 2013-09-01 06:10:52 EDT

Bulk closing of items that are on_qa and in old RHQ releases, which are out for a long time and where the issue has not been re-opened since.
