[Hawkular-dev] Hawkular Metrics 0.13.0 - Release

[Stefan Negrea]

Hello Everybody,

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.


Here is a list of major changes in this release:

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: https://github.com/hawkular/hawkular-metrics/tree/master/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 results are 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)
