Datadog employee here, you don't need to run your own collector to collect codecache usage. As it's exposed through JMX, the JMX collector can collect it http://docs.datadoghq.com/integrations/java/ http://docs.datadoghq.com/integrations/java/ . It doesn't by default though, so you'll need to configure it to collect the metrics from the "java.lang:name=Code Cache,type=MemoryPool" bean. We should add that in our default configuration.

If it's exposed through JMX, would it also be visible via something like jvisualvm?

  Not sure about jvisualvm, but it will definitely be visible in jconsole

    jvisualvm is largely a superset of jconsole, with a plugin interface, so it probably is. I have no idea how many other people actually use it though.
