| 2 | [[TracGuideToc]] |
| 3 | |
| 4 | Trac supports logging of system messages using the standard ''logging'' module part of Python 2.3 and newer. |
| 5 | |
| 6 | '''Note:''' If you are using a Python version older than 2.3, the Trac logging mechanism will be silently disabled. |
| 7 | |
| 8 | Logging is configured in the {{{[logging]}}} section in [wiki:TracIni trac.ini]. |
| 9 | |
| 10 | == Python 2.2 Workaround == |
| 11 | If you are using Python 2.2, however, note that the logging package from Python 2.3 works perfectly under 2.2 as well; you can just copy the entire {{{logging}}} directory from the Python 2.3 library into the Python 2.2 lib directory. Perhaps not the most elegant solution, but it works. |
| 12 | |
| 13 | |
| 14 | == Supported Logging Methods == |
| 15 | * '''none''' -- Suppress all log messages. |
| 16 | * '''file''' -- Log messages to a file, specified with the ''log_file'' directive in [wiki:TracIni trac.ini]. |
| 17 | * '''stderr''' -- Output all log entries to console ([wiki:TracStandalone tracd] only). |
| 18 | * '''syslog''' -- (UNIX) Send messages to local syslogd via named pipe '/dev/log'. |
| 19 | * '''winlog''' -- (Windows) Use the system's NT eventlog for Trac logging. |
| 20 | |
| 21 | == Log Levels == |
| 22 | 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. |
| 23 | |
| 24 | The levels are: |
| 25 | * ''CRITICAL'' -- Log only the most critical, typically fatal, messages. |
| 26 | * ''ERROR'' -- Request failures, bugs and errors. |
| 27 | * ''WARN'' -- Warnings, non-interrupting events. |
| 28 | * ''INFO'' -- Diagnostic information, log information about all requests. |
| 29 | * ''DEBUG'' -- Development messages, profiling, etc. Not fit for human consumption. |
