We need our application deployed in WebLogic Server to be up all the time, we cannot take risk the application downtime, and we cannot risk our business, but to monitor the servers which hold live applications need monitoring for the application availability.
WebLogic Server allows the usage of external tools and utilities for monitoring of internal application and components by executing various types of operation on MBeans like set() and get(), there are many more tools, utilities are in the market to provide monitoring feature for WebLogic Server and its deployed applications
Here in this post we are going to work/discuss on a Unique feature of WebLogic Server Called WebLogic Diagnostics Framework, In that we are going to work on Diagnostics Modules, with this we can monitor JMX Beans and system statistics.
For Testing purpose we are carrying out the experiment Production Mode Enabled - ProdDomain
