<br>
I am happy to announce release 0.8.0 of Hawkular Metrics. This short schedule release is anchored by major enhancements for metrics query aggregation, updated container support, and performance and stability enhancements.<br>
<br>
<br>
Here is a list of major changes in this release:<br>
<br>
1) Counters<br>
* Counter rates computations now avoid counter value resets (HWKMETRICS-218)<br>
* Counter rates are now aligned with the actual counter data used to calculate the rate (HWKMETRICS-284)<br>
<br>
2) Aggregate Metric Statistics<br>
* Added support for aggregate statistics based on multiple metrics<br>
* Gauges, counters, and counter rates are supported<br>
* Two methods of aggregation are currently available<br>
* uniform: data from multiple metrics is bucketed as originating from a single source and then statistics are computed on the entire set<br>
* stacked: statistics are first computed for every matching metric and then those statistics are stacked (added)<br>
* by default uniform statistics are enabled, stacking is enabled by stacked=true query parameter<br>
* The end-points are /gauges/data , /counters/data, /counters/data/rate<br>
* There is support to query by either tags or metrics ids; but not both<br>
* Relevant JIRAs: HWKMETRICS-292, HWKMETRICS-263, HWKMETRICS-264<br>
<br>
3) Data storage updates<br>
* Schema changes will require rebuilding the database<br>
* Reduced data storage footprint by limiting the size of metric type (HWKMETRICS-301)<br>
<br>
4) Container support<br>
* Secure connections are enabled between Hawkular Metrics and the Heapster sink (HWKMETRICS-217)<br>
* cqlsh can be access directly from within the Cassandra docker (HWKMETRICS-260)<br>
* Various updates to the Heapster sink to support latest Hawkular Metrics features: HWKMETRICS-285, HWKMETRICS-273, HWKMETRICS-276, HWKMETRICS-292<br>

<br>
Hawkular Metrics 0.9.0 & Beyond:<br>
1) Continuous agggregation - this has been a long term project goal and we are getting closer with refining the requirements and infrastructure<br>
2) Improved docker and kubernetes support - this is a long term goal for the project<br>
3) Improved tag support - to add bulk tag operations and tag queries<br>
4) Improved aggregate downsampling for multiple metrics - the project has now a base with recently added stacking and uniform support; the goal is to expand the aggregation methods<br>
