    ****************************************************************
    Previously, the PMI data can only be consumed internally using
    the
    Tivoli Performance Viewer (TPV) for graphing purposes, or it can
    also be exposed externally using the HTTP PerfServlet (in XML
    format) or via JMX MBeans. There were no available methods to
    convert the existing Performance Monitoring Infrastructure (PMI)
    data to Prometheus format.
    

Problem conclusion

  • A new metrics.ear installable application is now available in th
    WAS_HOME/installableApps directory, which
    provides a new way to consume WebSphere Application Server
    Performance Monitoring Infrastructure (PMI) metrics data.
    
    The metrics.ear application provides a way to use HTTP requests
    query the performance metrics for an entire WebSphere Applicatio
    Server administrative domain. It creates a Prometheus endpoint
    (/metrics) for your WebSphere Application Server runtimes to
    display PMI metrics in Prometheus format. The metrics available
    the Prometheus endpoint correspond to the set of metrics enabled
    the PMI configuration.
    
    The fix for this APAR is targeted for inclusion in fix pack
    8.5.5.20 and 9.0.5.7. For more information, see 'Recommended
    Updates for WebSphere Application Server':
