Re: [Hawkular-dev] Is this an applicable use-case for Hawkular

Hi Anton, We have integrated the Events feature in hawkular-alerts master branch: https://github.com/hawkular/hawkular-alerts You can follow the hawkular-alerts doc to build and test the component: http://www.hawkular.org/docs/components/alerts/index.html We will release a 0.6.0.Final version shortly. I have prepared some "HelloWorld" examples to show how to use Events on this repo: https://github.com/lucasponce/hawkular-examples/tree/master/events I want alto to publish a blog post once the release is out with more demo but I didn't want to delay my response to this topic without any feedback. The examples are using plain bash scripts over the REST API to show basic features. Don't hesitate to ask or give feedback, here, github, irc or event JIRA if you find something broken.
