A new module has been pushed to GIT repository: statsd. It was contributed by Eloy Coto, a recently added member to Kamailio development team.
The module provides the ability to send commands to statsd with different kind of information from the Kamailio configuration file. It provides native integration with statsd (https://github.com/etsy/statsd/) and graphite (http://graphite.wikidot.com/).
