Oracle WebLogic (Linux)

The Oracle WebLogic plugin for Linux allows you to monitor a number of performance and availability metrics for your WebLogic application server. If you can not find this plugin in the /usr/lib/panopta-agent/plugins folder, then your version of the Agent is out of date and you should update it to gain access to this feature.

Oracle WebLogic Configuration 

Once you install the agent you will need to add your WebLogic username, password, and WebLogic home to the /etc/panopta-agent/panopta_agent.cfg file as shown below:
