we have an application deployed in Tomcat servers and were able to chart out Tomcat measures like Cache Hits count, Cache Access count, JSP Monitor ,JSP Count . Recently we migrated our application from old servers to a new set of servers . But we were not able to chart out the out of the box measure for those new servers .
Can someone let us know what kind of permission needs to be provided to get those metrics .
Since those are JMX measures, my guess is you are not able to access the JMX on the new Tomcat server for some reason. To verify, you can create a measure, select a JMX measure, then browse the new tomcat JMX and see if it allows you to find "hitsCount" (for example).
Hi Sruthi -
The quick checks should be to verify that the Tomcat plugin is installed, and the applications have been re-started. As for permissions, there are no particular permissions to chart or use measures. If they are available and data is being collected for them, they will show data when charted. Are you unable to see the measures when charting, or is the issue that the measures don't have any data?
@ Dave M : Thanks for the reply . I tried to chart out Cache Hits count and select Measure splitting as Agent host . In the agent hosts lists , I can see only the old servers are available not the new ones .
Sruthi - Based on your reply to Dave, it sounds like indeed you cannot access the measures on the new servers. Can you verify permissions for these?
Also, yes the plugin for Tomcat measures would be placed on the AppMon Server. If the old hosts work (or did work) and you've not changed anything on the AppMon server in terms of configuration, the issue sounds like it lies with the new hosts and their reporting of metrics.
