Monitoring with WebSphere Application Server PMI

WebSphere® eXtreme Scale supports Performance Monitoring Infrastructure (PMI) when running in a WebSphere Application Server or WebSphere Extended Deployment application server. PMI collects performance data on runtime applications and provides interfaces that support external applications to monitor performance data. You can use the administrative console or the wsadmin tool to access monitoring data.

Before you begin

You can use PMI to monitor your environment when you are using WebSphere eXtreme Scale combined with WebSphere Application Server.

About this task

WebSphere eXtreme Scale uses the custom PMI feature of WebSphere Application Server to add its own PMI instrumentation. With this approach, you can enable and disable WebSphere eXtreme Scale PMI with the administrative console or with Java™ Management Extensions (JMX) interfaces in the wsadmin tool. In addition, you can access WebSphere eXtreme Scale statistics with the standard PMI and JMX interfaces that are used by monitoring tools, including the Tivoli® Performance Viewer.

Procedure

  1. Enable eXtreme Scale PMI.
    You must enable PMI to view the PMI statistics. See Enabling PMI for more information.
  2. Retrieve eXtreme Scale PMI statistics.
    View the performance of your eXtreme Scale applications with the Tivoli Performance Viewer. See Retrieving PMI statistics for more information.
