Heroku CLI Plugin for JMX

Uses ngrok to tunnel a JMX connection into a dyno.

$ heroku plugins:install heroku-jmx

Usage

Initialize your app (you'll need your ngrok auth token):

$ heroku jmx:init

Deploy your app:

$ git push heroku master

Look through your logs for this:

$ heroku logs -t
...
2016-06...app[web.1]: Start JConsole: heroku jmx:jconsole [email protected] 0.tcp.ngrok.io:13379

Then run that command:

$ heroku jmx:jconsole [email protected] 0.tcp.ngrok.io:13379

JConsole will open and information that it is an insecure connection (but it's actually secured via SSH).

To use VisualVM, leave the jmx:jconsole command running. Then set the VisualVM SOCKS proxy manually to localhost:1080.
