I have decided to monitor maximum heap usage and used heap of my EAP applications (using rhq/JON3.3) Pulled out both parameters for SINGLE node and it showing as max heap: 682.7MB and used heap to be 363.2MB
I also have pulled out the same for all the nodes in my environment and it is showing as max heap as 1.8G and used heap to be 1.4GB
My environment has more than 20 nodes,I checked the individual nodes and observed their heap usage to be more than 300 MB (each) so I concluded that Group metrics (second pic) displaying average (not sum) heap usage of all the nodes. If my conclusion is wrong, what does the values in second pic means? If I am right, how to view the sum (not average) heap usage of all the nodes..
If you are not getting what I am trying to say please let me know I will try much better to post my question clearly.Thanks in advance
