A blog post by Stefan Negrea

metrics | release

I am happy to announce release 0.12.0 of Hawkular Metrics. This release is anchored by Hawkular integration enhancements, under-the-cover refactoring and changes in code structure, and removal of the deprecated JAX-RS 1.1 implementation.

Major Changes

  1. Hawkular Authentication

    • When deployed part of Hawkular distribution, Hawkular Metrics uses Hawkular Accounts for authentication and authorization

    • Due to multi-tenant data segregation, Hawkular Accounts does both authentication and authorization since there are no specific permissions within Hawkular Metrics

    • For more details: (HWKMETRICS-69, HWKMETRICS-344)

  2. Performance Improvements

    • Removed obsolete code for tracking tenants; this increased for cases where data was written for a tenant that did not exist before (HWKMETRICS-341)

    • Removed the virtual clock handler (used to accelerate internal metrics clock) since it is no longer used (HWKMETRICS-340)

  3. JAX-RS 1.1 Implementation - Removed

    • The already deprecated JAX-RS 1.1 implementation of Hawkular Metrics has now been removed from the source tree and the modules consolidated

    • Going forward only JAX-RS 2.0 implementation of the REST API is available

  4. Wildfly 10 - Deploying & Running

    • Deploying and running the project on Wildfly 10 is now fully supported

    • Support for Wildfly 9 is now dropped

Hawkular Metrics Clients

One of Hawkular Metrics' objectives is to be easy to integrate with; providing language specific clients is an important component for fulfilling this objective. Here is the current list of official clients:


A big "Thank you" goes to John Sanda, Thomas Segismont, Mike Thompson, Matt Wringe, Michael Burman, Libor Zoubek, and Heiko Rupp for their project contributions.
