Trac Logging

Trac supports logging of system messages using the standard logging module part of Python 2.3 and newer. Warning: If you are using a version of Python older than 2.3, log messages will be silently thrown away!

If you are using Python 2.2, however, note that the logging package works perfectly under 2.2; you can just copy the entire logging directory from the Python 2.3 lib directory into the Python 2.2 lib directory.

Supported Methods

• none — Suppress all log messages.
• file — Log messages to a file, specified in the configuration (Using the log_file directive in trac.ini).
• stderr — Output all log entries to console. (tracd only)
• syslog — (UNIX) Send messages to local syslogd via named pipe '/dev/log'.
• winlog — (Windows) Use the system's NT eventlog for Trac logging.

Log Levels

The level of verbosity 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, messages.
• ERROR — Request failures, bugs and errors.
• WARN — Warnings, non-interrupting events.
• INFO — Diagnostic information, log information about all requests.
• DEBUG — Development messages, profiling, etc. Not for public consumption.
