Cluster Deployment Descriptor Reference : Collections Tab — Log Configurations Overview

Collections Tab — Log Configurations Overview
Each processing unit references a log configuration. The log configurations are defined in the Collections tab. See Configuring the Collections Tab (All OM Types). This section explains more about log configurations.
In a log configuration, you select a level of logging for each module within TIBCO BusinessEvents runtime software. You can also enable one or more outputs for the log information and configure them.
Levels
A level corresponds to how much logging is filtered out. They are ordered where all is lowest and off is highest:
Highest possible rank. Filters out all logging messages (turns logging off for the specified module).
Syntax
Enabling a lower level automatically enables the higher levels. For example, enabling info automatically enables fatal, error, and warning.
Assign each module to a level using a space-delimited list. The levels are not case sensitive. The syntax is as follows:
module1:level module2:level . . .
To assign a certain level of logging to all modules, use an asterisk:
*:info
This syntax means that logging for all modules is at the info logging level.
You can use the asterisk syntax and also specify exceptions that use a different logging level. For example:
*:info driver.tibrv:debug
This syntax means that all modules use logging level info, except the module driver.tibrv which uses debug level.
