    v1 v2  
    44Trac supports logging of system messages using the standard [http://docs.python.org/lib/module-logging.html logging module] that comes with Python. 
    55 
    6 Logging is configured in the {{{[logging]}}} section in [wiki:TracIni trac.ini]. 
     6Logging is configured in the `[logging]` section in [wiki:TracIni#logging-section trac.ini]. 
    77 
    88== Supported Logging Methods == 
    99 
    10 The log method is set using the `log_type` configuration option, which takes any of the following values: 
     10The log method is set using the `log_type` option in [wiki:TracIni#logging-section trac.ini], which takes any of the following values: 
     11 
    1112 '''none'':: Suppress all log messages. 
    12  '''file''':: Log messages to a file, specified with the `log_file` option in [wiki:TracIni trac.ini].  
     13 '''file''':: Log messages to a file, specified with the `log_file` option in [wiki:TracIni#logging-section trac.ini].  
    1314 '''stderr''':: Output all log entries to console ([wiki:TracStandalone tracd] only). 
    14  '''syslog''':: (UNIX) Send messages to local syslogd via named pipe `/dev/log`. 
    15  '''eventlog''':: (Windows) Use the system's NT eventlog for Trac logging. 
     15 '''syslog''':: (UNIX) Send all log messages to the local syslogd via named pipe `/dev/log`. By default, syslog will write them to the file /var/log/messages. 
     16 '''eventlog''':: (Windows) Use the system's NT Event Log for Trac logging. 
    1617 
    1718== Log Levels == 
    1819 
    19 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. 
     20The verbosity level of logged messages can be set using the `log_level` option in [wiki:TracIni#logging-section trac.ini]. The log level defines the minimum level of urgency required for a message to be logged, and those levels are: 
    2021 
    21 The levels are: 
    2222 '''CRITICAL''':: Log only the most critical (typically fatal) errors. 
    2323 '''ERROR''':: Log failures, bugs and errors.  
     
    2626 '''DEBUG''':: Trace messages, profiling, etc. 
    2727 
     28== Log Format == 
     29 
     30Starting with Trac 0.10.4 (see #2844), it is possible to set the output format for log entries. This can be done through the `log_format` option in [wiki:TracIni#logging-section trac.ini]. The format is a string which can contain any of the [http://docs.python.org/lib/node422.html Python logging Formatter variables]. Additonally, the following Trac-specific variables can be used: 
     31 '''$(basename)s''':: The last path component of the current environment. 
     32 '''$(path)s''':: The absolute path for the current environment. 
     33 '''$(project)s''':: The originating project's name. 
     34 
     35Note that variables are identified using a dollar sign (`$(...)s`) instead of percent sign (`%(...)s`). 
     36 
     37The default format is: 
     38{{{ 
     39log_format = Trac[$(module)s] $(levelname)s: $(message)s 
     40}}} 
     41 
     42In a multi-project environment where all logs are sent to the same place (e.g. `syslog`), it makes sense to add the project name. In this example we use `basename` since that can generally be used to identify a project: 
     43{{{ 
     44log_format = Trac[$(basename)s:$(module)s] $(levelname)s: $(message)s 
     45}}} 
     46
