Hello, I've implemented a peer for ganglia 3.1 in Java (Apache 2.0 license) [1,2,3]. By a peer, I mean that it both reports metrics (as do embedded-ganglia and hadoop-commons) but it also listens to and participates in the ganglia protocol. This means that it is capable of producing load balanced host reports just like gstat. It does not yet respond to telnet requests with an XML dump of the soft state, but that it an easy enough thing to do. I also have not yet worked through the unicast setup in any depth. Right now it joins a configured multicast group. It supports the 3.1 wire format and has most of the code required to support the earlier wire format.
The project does not yet come with any bundled host/app metrics collectors. However, we do have a variety of statistics collectors for the host level which we plan to port into (vmstat, iostat, and typeperf (allows metrics collection under windows)). There is also a per-process collector based on pidstat and JVM specific collectors. We plan to migrate those collectors into the bigdata-ganglia project, but they need to be decoupled from bigdata's[4] internal performance counter hierarchy first. This is currently being managed as part of the bigdata [4] project, but the ganglia module is under the Apache 2.0 license.
