docker-jolokia

Minimal Image with Apache Tomcat9, openjdk8-jre-base, jolokia and hawtio.

jolokia

Jolokia is remote JMX with JSON over HTTP.

It is fast, simple, polyglot and has unique features. It's JMX on Capsaicin.

hawtio

hawtio has lots of plugins such as: a git-based Dashboard and Wiki, logs, health, JMX, OSGi,

Apache ActiveMQ, Apache Camel, Apache OpenEJB, Apache Tomcat, Jetty, JBoss and Fuse Fabric

Since Version 1.4.0 needs jolokia an activated Jsr160RequestDispatcher.

This requires an activated authentication. An JOLOKIA_BASIC_AUTH environment variable can be used to add users for a Basic Authentication:

For an example:

JOLOKIA_BASIC_AUTH="jolokia:passed,spec:test"
