How to monitor JVM usages for Websphere Applications?

Question

I'm trying to monitor JVM usages in IBM Websphere Server. Normally I use jstat tool from the JDK but since that's not available with IBM WAS, is there any other tool available for the same?

Answer 1

WAS uses IBM's J9 JVM under the hood. So, some of the HotSpot JVM's debugging tool will not work with it. WAS exposes all details using Performance Monitoring Infrastucture(PMI). You should be able to get lots of metrics using it. You need to enable this feature in order to get metrics.
