Regenerating the Web server plug-in configuration file
After you modify the Request Metrics configuration, complete the following steps to regenerate the Web server plug-in configuration file. Regenerating ensures that the Web server plug-in recognizes the changes you made for the Request Metrics configuration. If you are making multiple changes to Request Metrics, then regenerate the plug-in configuration files once you have completed all changes.You must complete this step after you change the request metrics configuration. If you do not, the Web server plug-in might have different Request Metrics configuration data than the application server. This difference in configuration data might cause inconsistent behaviors for request metrics between the Web server plug-in and the appserver.
