Configuring Domain Log Filters

The WebLogic Server maintains a single domainwide log file, as described in the section "Logging Configuration for the Domain," earlier in this chapter. The domain log filter specifies which messages a WebLogic Server instance sends to the domain log. The message must pass all criteria in the filter to be logged. The configuration for the domain log filter specifies the minimum severity level of the message for the server to forward it to the domain log. The configuration also enables you to filter log messages based on the user ID for which the associated messages are sent. By default, messages are not filtered by user ID; therefore, messages from all user IDs are forwarded to the domain log. The domain log filter may also specify specific subsystems that the server will forward to the domain log. By default, messages are not filtered by subsystem; therefore, messages from all subsystems are forwarded to the domain log.
