;
; Logging Configuration
;
; In this file, you configure logging to files or to
; the syslog system.
;
; "logger reload" at the CLI will reload configuration
; of the logging system.

[general]
;
; Customize the display of debug message time stamps
; this example is the ISO 8601 date format (yyyy-mm-dd HH:MM:SS)
;
; see strftime(3) Linux manual for format specifiers.  Note that there is also
; a fractional second parameter which may be used in this field.  Use %1q
; for tenths, %2q for hundredths, etc.
;
;dateformat=%F %T       ; ISO 8601 date format
;dateformat=%F %T.%3q   ; with milliseconds
;
;
; This makes Asterisk write callids to log messages
; (defaults to yes)
;use_callids = no
;
; This appends the hostname to the name of the log files.
;appendhostname = yes
;
; This determines whether or not we log queue events to a file
; (defaults to yes).
;queue_log = no
;
; Determines whether the queue_log always goes to a file, even
; when a realtime backend is present (defaults to no).
;queue_log_to_file = yes
;
; Set the queue_log filename
; (defaults to queue_log)
;queue_log_name = queue_log
;
; When using realtime for the queue log, use GMT for the timestamp
; instead of localtime.  The default of this option is 'no'.
;queue_log_realtime_use_gmt = yes
;
; Log rotation strategy:
; none:  Do not perform any logrotation at all.  You should make
;        very sure to set up some external logrotate mechanism
;        as the asterisk logs can get very large, very quickly.
; sequential:  Rename archived logs in order, such that the newest
;              has the highest sequence number [default].  When
;              exec_after_rotate is set, ${filename} will specify
;              the new archived logfile.
; rotate:  Rotate all the old files, such that the oldest has the
;          highest sequence number [this is the expected behavior
;          for Unix administrators].  When exec_after_rotate is
;          set, ${filename} will specify the original root filename.
; timestamp:  Rename the logfiles using a timestamp instead of a
;             sequence number when "logger rotate" is executed.
;             When exec_after_rotate is set, ${filename} will
;             specify the new archived logfile.
;rotatestrategy = rotate
;
; Run a system command after rotating the files.  This is mainly
; useful for rotatestrategy=rotate. The example allows the last
; two archive files to remain uncompressed, but after that point,
; they are compressed on disk.
;
; exec_after_rotate=gzip -9 ${filename}.2
;
;
; For each file, specify what to log.
;
; For console logging, you set options at start of
; Asterisk with -v for verbose and -d for debug
; See 'asterisk -h' for more information.
;
; Directory for log files is configures in asterisk.conf
; option astlogdir
;
; All log messages go to a queue serviced by a single thread
; which does all the IO.  This setting controls how big that
; queue can get (and therefore how much memory is allocated)
; before new messages are discarded.
; The default is 1000
;logger_queue_limit = 250
;
; Any custom logging levels you may want to use, which can then
; be sent to logging channels. The maximum number of custom
; levels is 16, but not all of these may be available if modules
; in Asterisk define their own.
;custom_levels = foobar,important,compliance
;
[logfiles]
;
; Format is:
;
; logger_name => [formatter]levels
;
; The name of the logger dictates not only the name of the logging
; channel, but also its type. Valid types are:
;   - 'console'  - The root console of Asterisk
;   - 'syslog'   - Linux syslog, with facilities specified afterwards with
;                  a period delimiter, e.g., 'syslog.local0'
;   - 'filename' - The name of the log file to create. This is the default
;                  for log channels.
;
; Filenames can either be relative to the standard Asterisk log directory
; (see 'astlogdir' in asterisk.conf), or absolute paths that begin with
; '/'.
;
; An optional formatter can be specified prior to the log levels sent
; to the log channel. The formatter is defined immediately preceeding the
; levels, and is enclosed in square brackets. Valid formatters are:
;   - [default] - The default formatter, this outputs log messages using a
;                 human readable format.
;   - [plain]   - The plain formatter, this outputs log messages using a
;                 human readable format with the addition of function name
;                 and line number. No color escape codes are ever printed
;                 nor are verbose messages treated specially.
;   - [json]    - Log the output in JSON. Note that JSON formatted log entries,
;                 if specified for a logger type of 'console', will be formatted
;                 per the 'default' formatter for log messages of type VERBOSE.
;                 This is due to the remote consoles interpreting verbosity
;                 outside of the logging subsystem.
;
; Log levels include the following, and are specified in a comma delineated
; list:
;    debug
;    trace
;    notice
;    warning
;    error
;    verbose(<level>)
;    dtmf
;    fax
;    security
;    <customlevel>
;
; Verbose takes an optional argument, in the form of an integer level. The
; verbose level can be set per logfile. Verbose messages with higher levels
; will not be logged to the file.  If the verbose level is not specified, it
; will log verbose messages following the current level of the root console.
;
; Debug has multiple levels like verbose. However, it is a system wide setting
; and cannot be specified per logfile. You specify the debug level elsewhere
; such as the CLI 'core set debug 3', starting Asterisk with '-ddd', or in
; asterisk.conf 'debug=3'.
;
; Special level name "*" means all levels, even dynamic levels registered
; by modules after the logger has been initialized (this means that loading
; and unloading modules that create/remove dynamic logger levels will result
; in these levels being included on filenames that have a level name of "*",
; without any need to perform a 'logger reload' or similar operation).
; Note that there is no value in specifying both "*" and specific level names
; for a filename; the "*" level means all levels.  The only exception is if
; you need to specify a specific verbose level. e.g, "verbose(3),*".
;
; We highly recommend that you DO NOT turn on debug mode if you are simply
; running a production system.  Debug mode turns on a LOT of extra messages,
; most of which you are unlikely to understand without an understanding of
; the underlying code.  Do NOT report debug messages as code issues, unless
; you have a specific issue that you are attempting to debug.  They are
; messages for just that -- debugging -- and do not rise to the level of
; something that merit your attention as an Asterisk administrator.  Both
; debug and trace messages are also very verbose and can and do fill up
; logfiles quickly.  This is another reason not to have debug or trace
; modes on a production system unless you are in the process of debugging
; a specific issue.
