Trac Logging

Trac supports logging of system messages using the standard logging module part of Python 2.3 and newer.

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.
