Things to mention about Jolokia

As Jolokia represents a JMX-Interface it is highly recommended to not forward it to the internet!

Jolokia with Grizzly

When using Grizzly, you can connect to jolokia directly with the servers address, e.g.: http://oxserver1.8009/monitoring/jolokia

When using AJP, you need to enable forwarding for each server, keep in mind that those should be only accessable inside your intranet.

An Apache proxy_ajp.conf could look like this:

   <Location /internal>
       # restrict access to internal
       Order Deny,Allow
       Deny from all
       Allow from 127.0.0.1
       # you might add more ip addresses / networks here 
       # if the apache is not on the same machine as the OX-server 
       # Allow from 192.168 10 172.16
   </Location>
   ...
   <Proxy /internal/ox1/monitoring>
       ProxyPass ajp://oxhost1:8009/monitoring
   </Proxy>
   ...

Jolokia on oxhost1 is accessable by http://apacheaddress/internal/ox1/monitoring/jolokia .
