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 If you can not find this plugin in the /usr/lib/fm-agent/plugins folder, then your version of the Agent is out of date and you should update it to gain access to this feature.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/fm-agent/fm_agent.cfg file as shown below:
[weblogic]
username = weblogic
password = password123
wl_home = /opt/oracle/Oracle/Middleware/Oracle_Home/wlserver
Control Panel Configuration
First, select Oracle WebLogic from the catalog.
There are a number of available metrics that can be summed into 5 groups.
-
EJB Pool
-
EJB Transaction
-
Executive Queue
-
Servlet
-
Web App Component

If you would like to inspect the Oracle plugin in more detail you can find the python script for it in the /usr/lib/panopta-agent/plugins folder.
Oracle WebLogic 12c
Once you install the agent you will need to add your weblogic12c configuration block to the /etc/panopta-agent/panopta_agent.cfg file as shown below:
[weblogic12c]
classpath = (REQUIRED) A colon-separated Java CLASSPATH specification that points to the wlclient.jar and wljmxclient.jar files. These are installed with WebLogic and are generally found at $WL_HOME/wlserver/server/lib. If permissions issues prevent the agent user from accessing them in their default location, they can be copied to another location available to the agent such as $AGENT_HOME/share and referenced there in the classpath variable.
username = (OPTIONAL) If both username and password are present, used to authenticate the JMX API call
password = (OPTIONAL) If both username and password are present, used to authenticate the JMX API call
protocol = (OPTIONAL) The protocol used to access the JMX API. If not provided, defaults to iiop.
hostname = (OPTIONAL) The hostname used for the JMX connection. If not provided, defaults to localhost.
port = (OPTIONAL) The port to use for the JMX connection. If not provided, defaults to 7001.
jndi_name = (OPTIONAL) The Java Naming and Directory Interface name used to fine the WebLogic management beans. If not provided, defaults to weblogic.management.mbeanservers.runtime
jmx_url = (OPTIONAL) The full JMX URL used to access the WebLogic JMX API.
If not provided, this URL is built up from the previous configuration items.
