rsyslog 配置 二
# rsyslog configuration file
# For more information see /usr/share/doc/rsyslog-*/rsyslog_conf.html
# If you experience problems, see http://www.rsyslog.com/doc/troubleshoot.html
#### MODULES ####
####模块####
# The imjournal module bellow is now used as a message source instead of imuxsock
#加载输入模块（消息来源）
$ModLoad imuxsock # provides support for local system logging (e.g. via logger command)（提供对本地系统日志的支持（例如通过记录器命令））
$ModLoad imjournal # provides access to the systemd journal（提供对systemd日志的访问）
#$ModLoad imklog # reads kernel messages (the same are read from journald)（读取内核消息（从日志读取相同的消息））
#$ModLoad immark # provides --MARK-- message capability（提供--MARK--消息功能）
# Provides UDP syslog reception
#接收使用UDP 协议转发过来的日志
$ModLoad imudp
$UDPServerRun 514
# Provides TCP syslog reception
#接收使用TCP 协议转发过来的日志
#$ModLoad imtcp
#$InputTCPServerRun 514
#注意：两个协议可以同时监听
#### GLOBAL DIRECTIVES ####
#定义日志格式默认模板
# Where to place auxiliary files
$WorkDirectory /var/lib/rsyslog
# Use default timestamp format
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
$template myFormat,"%timestamp% %fromhost-ip% %msg%\n" #定义模板 $template tplname, string/list/subtree/plugin
$ActionFileDefaultTemplate myFormat #默认使用myFormat模板
# File syncing capability is disabled by default. This feature is usually not required, #默认情况下禁用文件同步功能。 通常不需要此功能
# not useful and an extreme performance hit
#$ActionFileEnableSync on
# Include all config files in /etc/rsyslog.d/ #将所有配置文件包含在/etc/rsyslog.d/
$IncludeConfig /etc/rsyslog.d/*.conf
# Turn off message reception via local log socket; #通过本地日志socket，关闭信息接收
# local messages are retrieved through imjournal now.
$OmitLocalLogging on
# File to store the position in the journal #文件存储在日志中的位置
$IMJournalStateFile imjournal.state
#### RULES ####
#定义规则
# Log all kernel messages to the console.
# Logging much else clutters up the screen.
#kern.* /dev/console #关于内核的所有日志都放到/dev/console（控制台）
# Log anything (except mail) of level info or higher.
# Don't log private authentication messages!
*.info;mail.none;authpriv.none;cron.none /var/log/messages
#记录所有日志类型的info级别以及大于info级别的信息到/var/log/messages，
#但是mail邮件信息，authpriv验证方面的信息和cron时间任务相关的信息除外
# The authpriv file has restricted access. #authpriv验证相关的所有信息存放在/var/log/secure
authpriv.* /var/log/secure
# Log all the mail messages in one place. #邮件的所有信息存放在/var/log/maillog; 这里有一个-符号, 表示是使用异步的方式记录, 因为日志一般会比较大
mail.* -/var/log/maillog
# Log cron stuff #计划任务有关的信息存放在/var/log/cron
cron.* /var/log/cron
# Everybody gets emergency messages #记录所有的大于等于emerg级别信息, 以wall方式发送给每个登录到系统的人
*.emerg :omusrmsg:*
# Save news errors of level crit and higher in a special file. #记录uucp,news.crit等存放在/var/log/spooler
uucp,news.crit /var/log/spooler
# Save boot messages also to boot.log #启动的相关信息存放在 /var/log/boot.log
local7.* /var/log/boot.log
# ### begin forwarding rule ###
#转发规则
# The statement between the begin ... end define a SINGLE forwarding #begin ... end之间的语句定义了一个SINGLE转发
# rule. They belong together, do NOT split them. If you create multiple #规则。 他们属于一起，不要分裂。 如果你创建多个
# forwarding rules, duplicate the whole block! #转发规则，重复整个块
# Remote Logging (we use TCP for reliable delivery) #远程日志记录（我们使用TCP可靠的传送）
# An on-disk queue is created for this action. If the remote host is #为此操作创建一个磁盘队列。 如果远程主机是down掉，消息被假脱机到磁盘，并在重新启动时发送。
# down, messages are spooled to disk and sent when it is up again.
#$ActionQueueFileName fwdRule1 # unique name prefix for spool files #假脱机文件的唯一名称前缀
#$ActionQueueMaxDiskSpace 1g # 1gb space limit (use as much as possible) #1gb空间限制（尽可能多使用）
#$ActionQueueSaveOnShutdown on # save messages to disk on shutdown #关闭时将消息保存到磁盘
#$ActionQueueType LinkedList # run asynchronously #使用链接列表模式
#$ActionResumeRetryCount -1 # infinite retries if host is down #如果主机关闭，则会无限重试
# remote host is: name/ip:port, e.g. 192.168.0.1:514, port optional
#*.* @@remote-host:514
*.* @@localhost:5000 #@@表示通过tcp协议发送 @表示通过udp进行转发
# ### end of the forwarding rule ###
