We have some documentation 

http://www.hawkular.org/docs/rest/rest-alerts.html

but this is a point we want to improve when we have some slot between releases.

If there is something wrong/broken, please, don't hesitate to comment (or if it's clear, feel free to open a JIRA and we'll work on it).

Thanks,
Lucas
