# 日志信息
# =================================================================

# Places to log to. Use multiple log_dest lines for multiple
# logging destinations.
# 记录日志，使用多个log_dest行对应多个日志信息的描述
#
# Possible destinations are: stdout stderr syslog topic file
# log_dest可能的选项有: stdout stderr syslog topic file
#
# stdout and stderr log to the console on the named output.
# stdout和stderr的日志输出在控制台
#
# syslog uses the userspace syslog facility which usually ends up
# in /var/log/messages or similar.
# syslog使用用户空间记录日志的级别通常保存在/var/log/messages或者邮件中
#
# topic logs to the broker topic '$SYS/broker/log/<severity>',
# 主题日志保存在代理服务器的主题日志路径下面 '$SYS/broker/log/<severity>'
#
# where severity is one of D, E, W, N, I, M which are debug, error,
# warning, notice, information and message. Message type severity is used by
# the subscribe/unsubscribe log_types and publishes log messages to
# $SYS/broker/log/M/susbcribe or $SYS/broker/log/M/unsubscribe.
# 当安全级别为D, E, W, N, I, M分别对应为调试, 错误, 警告, 注意, 信息, 消息.
# 消息安全类型用于订阅/取消订阅的消息类型时，发送的日志信息保存在
# $SYS/broker/log/M/susbcribe or $SYS/broker/log/M/unsubscribe
#
# The file destination requires an additional parameter which is the file to be
# logged to, e.g. "log_dest file /var/log/mosquitto.log". The file will be
# closed and reopened when the broker receives a HUP signal. Only a single file
# destination may be configured.
#
# Note that if the broker is running as a Windows service it will default to
# "log_dest none" and neither stdout nor stderr logging is available.
# Use "log_dest none" if you wish to disable logging.
log_dest file /var/log/mosquitto.log

# If using syslog logging (not on Windows), messages will be logged to the
# "daemon" facility by default. Use the log_facility option to choose which of
# local0 to local7 to log to instead. The option value should be an integer
# value, e.g. "log_facility 5" to use local5.
#log_facility 5

# Types of messages to log. Use multiple log_type lines for logging
# multiple types of messages.
# Possible types are: debug, error, warning, notice, information,
# none, subscribe, unsubscribe, websockets, all.
# Note that debug type messages are for decoding the incoming/outgoing
# network packets. They are not logged in "topics".
#log_type error
#log_type warning
#log_type notice
log_type all

# Change the websockets logging level. This is a global option, it is not
# possible to set per listener. This is an integer that is interpreted by
# libwebsockets as a bit mask for its lws_log_levels enum. See the
#log_facility 5

# 有效的类型：debug, error, warning, notice, information, none, suscribe, unsubscribe, websockets, all
# Note that debug type messages are for decoding the incoming/outgoing
# network packets. They are not logged in "topics".
# 注意：debug类型，消息会被解码为输入/输出的网络包，如果作为topics不会被记录到日志

# 设置websockets的日志级别，是一个全局的选项，但不是每个监听器都生效
# 可以当做libwebsockets的位掩码的整数作为lws_log_level的枚举
# 通过libwebsockets文档查看详情
# ‘log_type websockets’ 必须设置为生效才能设置这个参数
#websockets_log_level 0

# If set to true, client connection and disconnection messages will be included
#websockets_log_level 0

# If set to true, client connection and disconnection messages will be included
# in the log.
# 是否保存客户端的连接和断开连接的信息到日志
connection_messages true

# If set to true, add a timestamp value to each log message.
# 是否设置日志时间
log_timestamp true
