= Trac Logging = [[TracGuideToc]] 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 with the ''log_file'' directive 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'. * '''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 [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, 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. ---- See also: TracIni, TracGuide
