clip_image002This tutorial is prepared for Advanced WebLogic Administration and Automation. Setting up internal JMX MBean objects are the “best and ultimate practice” for applications’ monitoring infrastructure.

Outline:

  1. How to develop and register JMX MBean to Oracle WebLogic Server?
  2. How to check SERVER disk space by using JMX MBean on WebLogic?
  3. How to define WLSDM User Defined Metric Actions?
  4. How to delete or move Application logs automatically when given threshold exceeds for disc usage on SERVER?

Problem: The application which is deployed to Oracle WebLogic Server 12c (12.1.3) is increasing server disk space continuously and in peak times it makes the server disk usage 100%. Meanwhile, the service goes down and causes the service down-time.

Solution:

  1. Develop JMX MBeans which check server disk usage (JMX StandardMBean)
  2. Create alarm and notify when the disk usage is over 95% (JMX MBean Monitoring – UsedDiskSpace)
  3. For more information Read the complete article here & YoutTube (Video Tutorial) & Sample Java Source Code Project
