Log filters provide control over the log messages that get published. A filter uses custom logic to evaluate the log message content, which you use to accept or reject a log message; for example, to filter out messages of a certain severity level, from a particular subsystem, or according to specified criteria. Only the log messages that satisfy the filter criteria get published. You can create separate filters for the messages that each server instance writes to its server log file, standard out, memory buffer, or broadcasts to the domain-wide message log.
To create and configure a log filter:
The new log filter appears in the Log Filters table.
A filter expression defines simple filtering rules to limit the volume of log messages written to a particular log destination. See Configuration Options. For information on specifying filter expressions, see WLDF Query Language.
The filter and filter expression are listed in the Log Filters table.
After you finish
Assign the filter to one or more log message destinations. See Filter log messages.
