# 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

# Change the websockets logging level. This is a global option, it is not

# 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
