Develop performance monitoring applications with the PMI servlet

The performance servlet uses the Performance Monitor Infrastructure (PMI) to retrieve the performance information from WebSphere Application Server.

The performance servlet EAR file, perfServletApp.ear, is located in the /QIBM/ProdData/WebAS5/Base/installableApps directory. This servlet is deployed like other servlets. For information on deploying applications, see Install and uninstall applications. To use the performance servlet, follow these steps:

1. Deploy the servlet on a single application server instance within the domain.
2. After you deploy the servlet, you can invoke it to retrieve performance data for the WebSphere Application Server domain. To invoke the performance servlet, access this default URL:

   http://host:port/wasPerfTool/servlet/perfservlet

   where host is the name or IP address of your iSeries server and port is the internal HTTP server port for your instance.

The performance servlet provides performance data output as an XML document, as described by the provided document type definition (DTD). The output structure provided is called leaves. The paths that lead to the leaves provide the context of the data. See PMI servlet for more information about the PMI servlet output.
