Trac Logging

TracGuideToc

Trac supports logging of system messages using the standard logging module that comes with Python.

Logging is configured in the [logging] section in trac.ini.

Supported Logging Methods

The log method is set using the log_type configuration option, which takes any of the following values: 'none:: Suppress all log messages. file:: Log messages to a file, specified with the log_file option in trac.ini. stderr:: Output all log entries to console (tracd only). syslog:: (UNIX) Send messages to local syslogd via named pipe /dev/log. eventlog:: (Windows) Use the system's NT eventlog for Trac logging.

Log Levels

The verbosity level of logged messages can be set using the log_level directive in trac.ini. The log level defines the minimum level of urgency required for a message to be logged.

The levels are: CRITICAL:: Log only the most critical (typically fatal) errors. ERROR:: Log failures, bugs and errors. WARN:: Log warnings, non-interrupting events. INFO:: Diagnostic information, log information about all processing. DEBUG:: Trace messages, profiling, etc.
