Support for JMX notifications (events)

[Daniel Glöckner]

Hi,

A few days ago I asked a question in this group related to a certain use case for jmxtrans.

I want to use JMX to publish events to jmxtrans. Guillaume Lederrey pointed me to JMX notifications which are not supported by jmxtrans, yet.

If people believe that this adds value to the project I might spend some time on it and implement a prototype.

I've created an issue and started to explore the API.

First design question is how would we configure a subscription to certain notifications in jmxtrans?

Maybe similar to the following example where we subscribe to AttributeA/B/C of SomeMBean.

Kind regards,

Daniel

        {

          "obj": "com.example:type=SomeMBean",

          "type": "notification"

          "resultAlias": "attributeChanges",

          "attr": [

            "AttributeA",

            "AttributeB",

            "AttributeC"

          ],

          "outputWriters": [

            {

              "@class": "com.googlecode.jmxtrans.model.output.InfluxDbWriterFactory",

              "url": "http://127.0.0.1:8086/",

              "username": "admin",

              "password": "admin",

              "database": "collectd",

              "tags": {

                "application": "my-app"

              }

            }

          ]

        }

This looks very reasonable. We can always refine later on, but please go ahead!

Hi,

I've started some work on the topic. Please see here: https://github.com/dgloeckner/jmxtrans/commit/f46caf2b2168eb95daf6493bcde9e08920c795ba

The code is not tested yet as my kids keep me busy ;) but unit tests are passing.

Kind regards,

Daniel

If you already open a pull request, I'll be happy to comment on it :) Easier to track with a PR than adding comments directly on your repo...

I've put some questions there also.

Integration was already extended, as you suggested :)
