    13  '''file''':: Log messages to a file, specified with the `log_file` option in [wiki:TracIni#logging-section trac.ini]. Relative paths in `log_file` are resolved relative to the `log` directory of the environment.
    14  '''stderr''':: Output all log entries to console ([wiki:TracStandalone tracd] only).
    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.

    28 Note that starting with Trac 0.11.5 you can in addition enable logging of SQL statements, at debug level. This is turned off by default, as it's very verbose (set `[trac] debug_sql = yes` in TracIni to activate).

    32 Starting with Trac 0.10.4 (see [trac:#2844 #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/library/logging.html#logrecord-attributes Python logging Formatter variables]. Additonally, the following Trac-specific variables can be used:
    33  '''$(basename)s''':: The last path component of the current environment.
    34  '''$(path)s''':: The absolute path for the current environment.
     32onally, the following Trac-specific variables can be used:
     33 '''$(basename)s''':: The .
     34 '''$(path)s''':: The absolute path .
    3535 '''$(project)s''':: The originating project's name.
    3636
     
    3838
    3939The default format is:
    40 {{{
     40{{{
    4141log_format = Trac[$(module)s] $(levelname)s: $(message)s
    4242}}}
    4343
    4444In a multi-project environment where all logs are sent to the same place (e.g. `syslog`), it makes sense to add the project name. In this example we use `basename` since that can generally be used to identify a project:
    45 {{{
     45{{{
    4646log_format = Trac[$(basename)s:$(module)s] $(levelname)s: $(message)s
    4747}}}
