Description

Feature Request

Besides reading attributes the jolokia2 agent should be able to invoke operations from custom Mbeans through the JMX.

Proposal:

We would like to see operations to be captured from invoked actions

Current behavior:

Current behaviour supports only read requests and attributes ie: curl http://localhost:10012/jolokia/read/java.lang:type=Memory | python -m json.tool

Desired behavior:

I would like to have also operations supported for custom Mbeans(for our applications) created in Spring.boot. An example is: http://localhost:10162/jolokia/exec/org.springframework.boot:type=Endpoint,name=Health/health/ | python -m json.tool While I can see the result in command line I cannot capture it with telegraf

Research direction
Examine the existing jolokia2 input plugin in the telegraf repository (likely under plugins/inputs/jolokia2). Understand how read requests are implemented and how the HTTP client interacts with the Jolokia agent. Then extend the plugin to support exec requests by adding a new configuration option for operations. Key files to modify may include plugins/inputs/jolokia2/jolokia2.go and any related configuration. Check previous comments for additional requirements.
