Description Mike Thompson 2013-07-25 21:54:45 UTC

Description of problem:
With the new Consolidated metrics screen, we can now add multiple metric graphs to dashboards in a single click via selecting multiple metric rows and pushing the  'Add to Dashboard' button. This new capability of adding multiple is now causing hibernate staleState exceptions.


Version-Release number of selected component (if applicable):
RHQ 4.9.0 snapshot after merge of Consolidated Metrics

How reproducible:
Sometimes, depends on load.


Steps to Reproduce:
1.For a resource go to the inventory detail --> monitor --> metrics tab (http://192.x.x.x:7080/coregui/#Resource/10021/Monitoring/Metrics)
2.Select several metric rows
3.Click the 'Add To Dashboard' button.
