JOPR is an open source project from Redhat to develop complex management platform. JOPR is agent based JAVA/J2EE system, where agent is standalone JAVA running and server runs on top of JBOSS Application Server(AS). It can be used to manage JBOSS AS, Tomcat, Apache as well as Oracle, and any IT resources.
JBoss Operations Network (JBoss ON) is commercial offer of JOPR in form of support service by Redhat.
JOPR is developed on top of RHQ project. RHQ serves as an maven upstream project for JOPR. RHQ consists of GUI management console, agent container and a set of agent plugins for management of common IT resources.
JOPR extends RHQ by adding additional plugins for JBoss App Server, Tomcat Web Server, etc. . JOPR version 2.2.0 is corresponding with RHQ version 1.2.0.
The original of RHQ is Hyperic HQ. Redhat and Hyperic work together to extract common reusable parts of Hyperic HQ and maintain it as RHQ. The aim is to create a common infrastructure for developing management's application. That is why the project named RHQ, where R stand for Redhat.

My 2 cents.
On the rhq-agent.sh script have a little mistake on the line 207. When you try to start the script a error occur. Unexpected error... The patch this remove the second equal "==" on the if statement.
Now , one question.
I recently install the latest version of jopr-server, and then configure the agent.
But when i start the agent it's take a hour, day, week and does not start.. i only have the message "The agent does not have plugins - it will now wait for them to be downloaded..." ..
do you know how can i fix this ??
thanks
Michi
Michi,
That is probably due to problems with the hostname/I.P. resolution.
