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.
