= Trac Logging = [[TracGuideToc]] Trac supports logging of system messages using the standard [http://docs.python.org/lib/module-logging.html logging module] that comes with Python. Logging is configured in the {{{[logging]}}} section in [wiki:TracIni 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 [wiki:TracIni trac.ini]. '''stderr''':: Output all log entries to console ([wiki:TracStandalone 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 [wiki:TracIni 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. ---- See also: TracIni, TracGuide, TracEnvironment
