Configuration of WLJVMRockitTest

The WLJVMRockitTest exposes runtime data about the JRockit Virtual Machine (VM) that is running the current WebLogic Server instance. The default parameters associated with this test are as follows:

  • The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

  • In the HOST text box, the host name of the server for which the test is to be configured has to be specified.

  • The port number to which the selected WebLogic server is listening to has to be specified in the PORT textbox.

  • The USER text box, indicates  the admin user name of the WebLogic server being monitored.

  • The PASSWORD text box, indicates the password of the specified admin user.

  • Confirm the password by retyping it in the CONFIRM PASSWORD text box. 

  • If the specified password needs to be encrypted, set the ENCRYPTPASS flag to YES. Otherwise, set it to NO. By default, the YES option will be selected.

  • In the SERVER text box, specify the name of the specific server instance to be monitored for the WebLogic server. The default value is localhome.

  • In the URL text box, specify the URL to be accessed to collect metrics pertaining to the WebLogic server. By default, this test connects to a managed WebLogic server and attempts to obtain the metrics of interest by accessing the local Mbeans of the server. This parameter can be changed to a value of http://<adminserverIP>:<adminserverPort>. In this case, the test connects to the WebLogic admin server to collect metrics pertaining to the managed server (specified by the HOST and PORT). The URL setting provides the administrator with the flexibility of determining the WebLogic monitoring configuration to use. 

    • Note:

    If the admin server is to be used for collecting measures for all the managed WebLogic servers, then it is mandatory that the egurkha war file is deployed to the admin server, and it is up and running. 

  • The VERSION textbox indicates the version of the Weblogic server to be managed. The default value is "none", in which case the test auto-discovers the weblogic version. If the value of this parameter is not "none", the test uses the value provided (e.g., 7.0) as the weblogic version (i.e., it does not auto-discover the weblogic server version). This parameter has been added to address cases when the eG agent is not able to discover the WebLogic server version.

  • The USEWARFILE flag indicates whether monitoring is to be done using a Web archive file deployed on the WebLogic server (in which case, HTTP/HTTPS is used by the server to connect to the server). If this flag is set to No, the agent directly connects to the WebLogic server using the T3 protocol (no other file needs to be deployed on the WebLogic server for this to work). Note that the T3 protocol-based support is available for WebLogic servers ver.9 and above.

  • In the WEBLOGICJARLOCATION text box, specify the location of the WebLogic server's java archive (Jar) file. If the USEWARFILE flag is set to No, then the weblogic.jar file specified here is used to connect to the corresponding WebLogic server using the T3 protocol. Note that the T3 protocol-based support is available for WebLogic servers ver.9 and above.

  • If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS check box will appear in this page. Clicking on this check box will allow you to apply the configuration to all/selected components of that type.

  • Once the necessary values have been provided, clicking on the UPDATE button will register the changes made.

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of "none" in the parameter value indicates that the corresponding parameter value can be changed if required.

Note:

The WLJVMRockitTest will work only if the following conditions are fulfilled:

  • The Weblogic Server must be launched on the JRockit JVM
  • The managementapi.jar should be on the Weblogic server's startup classpath
