I am happy that you are able to monitor your backend datasource JDBC monitoring. Yes, you can monitor all your datasources in the same dashboard.
Other APM tools injects runtime codes to your codes which creates a lot of overhead on your JVM instances. WLSDM uses native method and that’s why we call “native WebLogic monitoring”.
On the other hand; please follow “Generic DevOps MBean” tutorials and build your own dashboards and automate your WebLogic management.
