  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
