Description Joseph Marques 2008-12-22 04:11:00 UTC

instead of printing the performance statistics for dynagroup recalculation to the RHQ Server's log, write support for exposing rich performance metrics on a groupDefinition-by-groupDefinition basis through a monitor mbean.

Comment 1 Joseph Marques 2008-12-22 04:19:18 UTC

rev2516 - performance metrics for work done by recalculation thread for group defs / dyna groups; 
a new service - "RHQ Server Group Definition / DynaGroups Subsystem" - under the RHQ Server exists to wrap this functionality; 
a "get statistics" method exist and will retrieve metrics on a groupDefinition-by-groupDefinition basis;
clear statistics will reset them to zero (as will a server restart); 
four measurement definition exist on the service itself to help graph overall group definition metrics over time;

Comment 2 Jeff Weiss 2008-12-24 15:50:21 UTC

Is this a first-level feature, or just something to help with debugging the dynagroup recalculation feature?

Comment 3 Jeff Weiss 2009-01-06 19:14:46 UTC

I added some dynagroups with recalc, the monitor graphs and tables appear to be accurate.  The dynagroup sizes did increase when I added resources.  Everything else *looks* right but for instance calc time I have no way to verify independently.  rev2522
