We are using Introscope to monitor our WebLogic environment. With this, we are currently capturing the JVM heap size (Bytes in use/total, and heap used).
Does Introscope provide the ability to monitor/capture the PermGen (-XX:MaxPermSize) bytes in use/total, etc. as well?
Yes. Enable GCMonitor by ensuring that GCMonitor.jar file is available in agent's core/ext directory and introscope.agent.gcmonitor.enable is set to true in its I IntroscopeAgent.profile file.
Once successfully executed, you should see the following metrics under the Agent's "GC Monitor|Memory Pools" tree in the Investigator:
PS Eden Space
PS Old Gen
PS Perm Gen
PS Survivor Space
