Enable Application Response Measurement

Before enabling Application Response Measurement (ARM), install an appropriate ARM implementation on all WAS nodes. Refer to the appropriate ARM implementation documentation. Verify with your ARM agent provider that the ARM agent is supported with the request metrics in WebSphere.

Note that Request Metrics in the Web server plug-in is not integrated with ARM in WAS v5.0.x. Therefore, Request Metrics in the Web Server plug-in ignores ARM, if enabled.

1. Install the appropriate ARM implementation

   1. Change the startup command for the appservers to include the following

      -Dcom.ibm.websphere.pmi.reqmetrics.ARMIMPL=ARMIMPLNAME
      

      ARM support is dependent on Request Metrics support. If enabled, and an appropriate ARM implementation is defined to the server run times, then the ARM implementation is called as requests enter WAS processes and when JDBC calls are made, using EJB 2.0 data sources.

2. Open the administrative console.

3. Click Troubleshooting > PMI Request Metrics in the console navigation tree.

4. Select the check box in the enableARM field.

5. Click Apply or OK.

6. Click Save.

Regenerate the Web server plug-in configuration file.
