Hello @mauricio_capiz 

It seems you are looking for the hung threads. We are using a builtin feature 'Use JMX/PMI extension editor to add custom metrics without coding.' to get the hung threads for the traditional WebSphere.

You can try this feature in case it is available for Weblogic. Otherwise, you might have to use your own custom-built OneAgent extension.

Regards,

Babar
