Watching a Logstash JVM via Datadog

I would very much like to be able to watch the Logstash hosts' JVMs on Datadog, the way we can with Elasticsearch.

Does anyone have a datadog config file for this? Is anything special needed to enable say JMX to allow the data gathering?

I really want to have a graph of Logstash heap usage and GC times on my ES dashboard...

Thanks
