WebLogic 8

Configuration

Before using the WebLogic monitor, the WebLogic server jar must be installed in NeoLoad jmxlib/weblogic8 directory.

Copy the weblogic.jar file from the WebLogic server/lib directory to jmxlib/weblogic8 directory. After copying the files, it is unnecessary to restart NeoLoad. The files are automatically synchronized with the Monitoring Agent once the changes have been made.

Connection settings

Defining a monitor to a WebLogic server requires the name or IP address of the machine to be monitored, as well as the connection port (the default port is 7001). In addition to these settings, the domain to be monitored must be provided, together with the valid user account used to connect to the WebLogic Administration Console.

Create a WebLogic 8 monitor

NeoLoad makes it possible to create a new monitor either using the monitored machine creation wizard, as described in Create and configure a monitored machine, or from an existing monitored machine, as described in Create and configure a monitor.

NeoLoad displays a list of the EARs (Enterprise Archive) and WARs (Web Application archive) deployed on the configured server. It then automatically selects the most appropriate counters for each of the selected applications.

Available counters

The first tree level displays all the servers running within the WebLogic Server domain. For each WebLogic server, the counters are:
