Hawkular Metrics 0.13.0 - Release
by 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)

Issues installing Hawkular Service and Alert
by Hassnan Khan
My name is Hassnan Khan and I work at Fandango in the NOC department. We
use an ELK stack to process our logs into readable data that we see on
Kibana (4.6.4) / ElasticSearch 2.4.x. We've been trying to get a standalone
alerting system and haven't had much luck. I came across Hawkular Services
+ Alerts and thought this is something we could possibly use.
Unfortunately, we haven't been able to install it successfully. We've tried
all the installation guides on github + hawkular blogs and keep getting an
error when trying to connect to Cassandra even though it is obviously
running.
Is there any tips you can give on successfully installing the suite?

hawkular wildfly agent - feed ID
by John Mazzitelli
There was some concern that the feed ID autogenerated by the agent might not be what a person always wants (e.g. feed ID for WF10 agents will be the unique UUID of the wildfly server).
So, if you want to define your own feed ID, you can configure it now. In the agent's standalone.xml <storage-adapter> you can specify a feedId attribute if you want. By default, it isn't specified, so the agent will autogenerate a unique feed ID for itself (this should really be the normal mode of operation, but some people like to complain, so I made it easy to shut them up :-)
This is in master. Will be in the next release.
