; 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.
