WebSphere eXtreme Scale Administration Guide >
Monitor the deployment environment
You can use APIs, MBeans, logs, and utilities to monitor the performance of the application environment.
- Statistics overview
Statistics in WebSphere eXtreme Scale are built on an internal statistics tree. The StatsAccessor API, Performance Monitoring Infrastructure (PMI) modules, and MBean API are built from the internal tree.- Monitor with the statistics API
The Statistics API is the direct interface to the internal statistics tree. Statistics are disabled by default, but can be enabled by setting a StatsSpec interface. A StatsSpec interface defines how WebSphere eXtreme Scale should monitor statistics.- Monitor performance 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.- Use Managed Beans (MBeans) to administer the environment
You can use several different types of Java™ Management Extensions (JMX) MBeans to administer and monitor deployments. Each MBean refers to a specific entity, such as a map, eXtreme Scale, server, replication group, or replication group member.- Use the xsAdmin sample utility
With the xsAdmin sample utility, you can format and display textual information about the WebSphere eXtreme Scale topology. The sample utility provides a method for parsing and discovering current deployment data, and can be used as a foundation for writing custom utilities.- Vendor tools
WebSphere eXtreme Scale can be monitored using several popular enterprise monitoring solutions. Plug-in agents are included for IBM Tivoli Monitoring and Hyperic HQ, which monitor WebSphere eXtreme Scale using publicly accessible management beans. CA Wily Introscope uses Java method instrumentation to capture statistics.- Logs and trace
You can use logs and trace to monitor and troubleshoot the environment. Logs are in different locations depending on the configuration. You might need to provide trace for a server when you work with IBM support.
