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.
You can use PMI to monitor your environment when you are using WebSphere eXtreme Scale combined with WebSphere Application Server.
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.
For more information about the wsadmin tool, see Accessing Managed Beans (MBeans) using the wsadmin tool.
