A blog post by Stefan Negrea

metrics | release

I am happy to announce release 0.13.0 of Hawkular Metrics. This release is anchored by Hawkular integration enhancements, under-the-cover refactorings and fixes, and a new bulk data generation tool.

Major Changes

  1. Data Generation Tool

    • A new tool that generates bulk metrics data to be used in performance and load testing.

    • It generates directly Cassandra data files (SSTables), which leads to a very fast generation process for large amounts of metrics data.

    • For more details: Data Generator, HWKMETRICS-355

  2. Receive Metrics via Hawkular Bus

    • When deployed within Hawkular distribution, the project now accepts metrics via the Hawkular Bus; until now only the REST API had support for Metrics insertion.

    • Hawkular Metrics currently support publishing of newly inserted metrics to the bus and receiving metrics via the bus.

    • For more details: HWKMETRICS-347, HWKMETRICS-352

  3. Sorted Stacked Metrics Results

    • When requesting stacked metrics aggregation the result is now ordered HWKMETRICS-353

  4. External Integrations

    • Heapster sink now divides storing to multiple calls. This is an improvement over the initial implementation that had one REST API call per metric (HWKMETRICS-290)

    • ptrans now works with a Hawkular Metrics instance protected by Hawkular Accounts via Hawkular distribution (HWKMETRICS-342)

    • Grafana integration via Influxdb compatible end-point allows connections to a Hawkular Metrics instance protected by Hawkular Accounts via Hawkular distribution (HWKMETRICS-343)

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.
