JMS Monitor

The JMS Monitor is a utility for monitoring raw JMS messages. It is a debug tool for developers.

After entering a JMS "Topic" like "LOG", "ALARM", "TALK" etc., it will display received messages. It is possible to enter a list of comma-separated topics.

The "Clear" button removes received messages from the table.

Message Detail

Message detail for a selected row is available via Properties View.

You can open the Properties view by double-clicking on a message in the table.

The application is currently limited to "Map" and "Text" messages.

Preferences

The JMS server URL is configured via Eclipse preferences. Initial defaults are in file preferences.ini of the JMS Monitor plugin; the application's plugin_customization.ini can override, and finally they can also be changed via the preference GUI:

JMS Server URL: Specifies the server URL, also displayed in the JMS monitor GUI. Since the URL may list more than one JMS server, the GUI also displays the srever to which the tool actually connected.
JMS User, Password: User and password used to establish the connection to the JMS server. They can often be left blank.
Max Message Count: If the JMS monitor continued to display every received message, this would consume a lot of memory. The tool therefore employs a ring buffer. By default, it only keeps the last 500 messages, but you can adjust that number.
