APM 10.7 agent is working fine on running Weblogic However after upgrade to Weblogic, the agent is causing CPU overhead compared to the older WL version. The new WL runs on the same server so everything is the same (the app, the environment, the Hardware), only the WL version is different and it causes this huge overhead with enabled agent. if the agent is disabled the agent, the overhead disappears.


Release : 10.7.0

Component : APM Agents


We disabled following agent features which seems to improve performance. -> disabled all items of step 5.
additionally disabled following feature:
disable the Platform monitor.
disable all extension in ./extensions directory.
disabled jms.pbd

These above steps improved performance.
