    2020The 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:
    … …  
    2626 '''DEBUG''':: Trace messages, profiling, etc.
    2727
    28 Additionally, you can  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.
     28Note 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 The output format for log entries can be specified 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:
     32Starting 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:
    3333 '''$(basename)s''':: The last path component of the current environment.
    3434 '''$(path)s''':: The absolute path for the current environment.
    … …

    3939The default format is:
    40 {{{#!ini
     40{{{
    4141log_format = Trac[$(module)s] $(levelname)s: $(message)s
    4242}}}

    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 {{{#!ini
     45{{{
    4646log_format = Trac[$(basename)s:$(module)s] $(levelname)s: $(message)s
    4747}}}
