Manually configuring the data collector to monitor dynamic cluster servers
You can configure the data collector to monitor application server instances in a dynamic cluster by adding some data collector configuration parameters to the server template that was used to create the dynamic cluster server instances. This is an alternative method to configure dynamic cluster server instances to creating the server templates specific for the WebSphere® Applications agent.
About this task
To configure the data collector for dynamic cluster monitoring, you must create two settings files, and then manually add settings in the WebSphere administrative console to modify the dynamic server template. The runtime directory is created automatically when the data collector is started for the application server instance. Note that any upgrade to the server template will erase these changes that you made in this way.
- The cluster name cannot contain a space.
- You must make manual changes to the WebSphere Application Server configuration for data collectors as the WebSphere administrative user.
- You must be an experienced WebSphere administrator to make manual changes to the WebSphere Application Server for data collection. Any error in the manual configuration change can result in the application server not starting.
- If you manually configure the data collector to monitor application server instances, you cannot use the unconfiguration utility to unconfigure the data collector. To unconfigure the data collector, you must manually change the settings back.

Optional: Showing actual JVM name to distinguish cluster members
About this task
Sometimes, the cluster member names are truncated due to the character length limit. In this case, you can specify the actual JVM name to be used for the middle qualifier in the agent instance name.
Procedure
Perform the following steps to show actual JVM name in the agent instance name:
