Trac Logging

Table of Contents

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.
