Abstract

Prometheus endpoint for Performance Monitoring Infrastructure (PMI) metrics on Websphere Application Server traditional

Download Description

PH24409 resolves the following problem:

ERROR DESCRIPTION:
Adding a Prometheus endpoint to scrape Performance Monitoring Infrastructure (PMI) metrics with an installable application on WebSphere Application Server traditional.

LOCAL FIX:

PROBLEM SUMMARY:

USERS AFFECTED:
All users of IBM WebSphere Application Server

PROBLEM DESCRIPTION:
A new metrics.ear application to create a Prometheus endpoint for your WebSphere Application Server to display PMI metrics in Prometheus format.

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) metrics data to Prometheus format.
RECOMMENDATION:
None

PROBLEM CONCLUSION:
A new metrics.ear installable application is now available in the /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 to query the performance metrics for an entire WebSphere Application
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': https://www.ibm.com/support/pages/node/715553
