Monitoring and collecting data from Jolokia

Jolokia is remote JMX with JSON over HTTP. It’s a JMX-HTTP bridge giving an alternative to JSR-160 connectors. It is an agent based approach with support for many platforms. In addition to basic JMX operations it enhances JMX remoting with unique features like bulk requests and fine grained security policies.

How it works

This plugin will allow you to extract metrics from Jolokia compatible APIs. It will capture the metrics from the metrics endpoint specified.


The plugin needs to be installed together with a CoScale agent, instructions on how to install the CoScale agent can be found here. If you want to monitor Jolokia inside Docker containers using CoScale, check out the instructions here.
