Introduction
QMan is a bridge that enables remote management of one or more brokers.
Depending on your needs, remote management can be exposed using JMX or WS-DM. The difference between two approaches is that in the first one only a Java client is supported, while WS-DM is language independent and therefore the corresponding management entity (client) should only able to speak WS-DM dialect.
As conseguence of that we will divide the following documentation under two perspectives.
In the picture below you can have a big picture about the working environment where QMan runs :

As you can see QMan supports three different clients :
- a Java (Application) Client which is using Java Management Extensions (JMX) API for interaction; Note that this could be a standalone application client or a JEE application (Web & Business components);
- a WS-DM enabled management client which could be an application / middleware / command line tool that is able to communicate with WS-DM dialect;
- the third client (Web Browser) is not really a management client but it refers to administration console of QMan WS-DM. This is part of QMan Web Application and allows administration / management of QMan itself.
QMan Messages
Each log message produced by Qman has the following format :
<DATE> <PRIORITY> <MODULE> <MESSAGE-ID> : <MESSAGE>
Where :
- <DATE> : The date and time at which the message was added;
- <PRIORITY> : The priority level. Could be one of the following : DEBUG, WARN, INFO, ERROR, FATAL;
- <MODULE> : The component which generated the log;
- <MESSAGE-ID> : A message identifier. Each message has a unique id. It has the following format <QMAN-XXXXXXX>;
- <MESSAGE> : The log message. Data recorded in this field should be ignored by analysis tools because it could change.
