Configuration of JmxConnectorTest

This test reports the availability of the target Java application, and also indicates whether JMX is enabled on the application or not. In addition, the test promptly alerts you to slowdowns experienced by the application, and also reveals whether the application was recently restarted or not.

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. By default, this is set to 1 hour.

  • 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 at which the specified HOST listens should be specified in the PORT listbox.

  • For the eG agent to collect metrics from the target IBM WebSphere Liberty server, the local connector should be enabled on the target server. Once the connector is enabled, a com.ibm.ws.jmx.local.address file will be created in the ${server.output.dir}/logs/state folder. The eG agent uses this file to connect to the target server and collect the required metrics from it. Therefore, specify the exact path to this file in the SERVICE URL PATH text box. For example, in case of Windows environments, the Service URL Path can be C:\wlp\usr\servers\server1\logs\state and in case of Linux environments, the SERVICE URL PATH can be /opt/wlp/ur/servers/server1/logs/state.

  • Specify the duration (in seconds) for which this test should wait for a response from the target Java application. If there is no response from the target beyond the configured duration, the test will timeout. By default, the TIMEOUT parameter is set to 240 seconds.

  • 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.
