Is there anything blocking this PR?

[smillidge]

Nope just some bookkeeping on our side to create an issue number for the release notes and a corresponding PR into 4.x branch which we will do.

Hi @kvalev, can you please explain shortly how to use this feature?

[kvalev]

It basically allows bulk reading of monitoring data, so instead of reading it one by one

curl -X GET \
  http://localhost:4848/rest-monitoring/rest/read/java.lang:type=Memory
curl -X GET \
  http://localhost:4848/rest-monitoring/rest/read/java.lang:type=Runtime

you can now do it within a single request:

curl -X POST \
  http://localhost:4848/rest-monitoring/rest/ \
  -H 'Content-Type: application/json' \
  -d '[{"type":"read","mbean":"java.lang:type=Runtime","attribute":["Uptime"]},{"type":"read","mbean":"java.lang:type=Memory","attribute":["HeapMemoryUsage","NonHeapMemoryUsage"]},{"type":"read","mbean":"java.lang:type=Threading","attribute":["ThreadCount"]},{"type":"read","mbean":"java.lang:type=OperatingSystem","attribute":["ProcessCpuTime"]}]'

This will allow integrating it with the jolokia module in metricbeat, although I havent tested it yet.
