    ############ GENERAL PARAMETERS #################

    ### Option: PidFile
    # Name of PID file.
    #
    # Mandatory: no
    # Default:
    # PidFile=/tmp/zabbix_agentd.pid
    # PidFile=PID路径
    # 说明:指定程程序PIDFILE路径,可修改到其它路径,但SNC不建议修改

    PidFile=/var/run/zabbix/zabbix_agentd.pid

    ### Option: LogFile
    # Name of log file.
    # If not set, syslog is used.
    #
    # Mandatory: no
    # Default:
    # LogFile=
    # LogFile=路径
    # 说明:客户端AGENT运行产生的日志文件路径,可修改到其它路径,如/var/log/zabbix_agnetd.log,视具体情况修改,也可保持默认

    LogFile=/var/log/zabbix-agent/zabbix_agentd.log

    ### Option: LogFileSize
    # Maximum size of log file in MB.
    # 0 - disable automatic log rotation.
    #
    # Mandatory: no
    # Range: 0-1024
    # Default:
    # LogFileSize=1
    # LogFileSize=数字
    # 说明:AGENT产生日志大小控制,默认1M,若为0,则表示不产生任何日志,数字范围(1-1024M)不建议关闭日志功能,建议保持默认

    LogFileSize=0

    ### Option: DebugLevel
    # Specifies debug level
    # 0 - no debug 无日志级别
    # 1 - critical information 灾难信息级别
    # 2 - error information 一般错误信息级别
    # 3 - warnings 警告级别
    # 4 - for debugging (produces lots of information) 调试级别
    # 说明:0~4级别,日志产生量在相同单位时间,生成的日志量为递增,即0级别日志量最少,4级别最多,默认3级别,建议视具体情况,自行把握
    #
    # Mandatory: no
    # Range: 0-4
    # Default:
    # DebugLevel=3

    ### Option: SourceIP
    # Source IP address for outgoing connections.
    #
    # Mandatory: no
    # Default:
    # SourceIP=
    # SourceIP=IP地址
    # 说明:当系统设置有多个IP时,需要指定一个IP与二级代理或服务端通信,若系统只有一个IP,也建议指定一个IP

    ### Option: EnableRemoteCommands
    # Whether remote commands from Zabbix server are allowed.
    # 0 - not allowed
    # 1 - allowed
    #
    # Mandatory: no
    # Default:
    # EnableRemoteCommands=0
    # EnableRemoteCommands=0或1
    # 说明:是否允许在本地执行远程命令,建议设置为“允许”,因为SNC对命令下发功能进行了二次开发,功能强大,极大的方便日志运维工作

    ### Option: LogRemoteCommands
    # Enable logging of executed shell commands as warnings.
    # 0 - disabled 不产生日志
    # 1 - enabled 产生日志
    #
    # Mandatory: no
    # Default:
    # LogRemoteCommands=0
    # LogRemoteCommands=1或0
    # 说明:在参数EnableRemoteCommands=1的情况下,执行远程命令是否保存操作日志,若已设置EnableRemoteCommands=1
    # 建议LogRemoteCommands=1,以便日后查证。若EnableRemoteCommands=0,此参数不生效

    ##### Passive checks related
    # 与被动模式有关的参数设置
    # 什么是被动模式?
    # 被动模式下,由二级代理或服务端主动请求AGENT,去获取所采集到的监控数据

    ### Option: Server
    # List of comma delimited IP addresses (or hostnames) of Zabbix servers.
    # Incoming connections will be accepted only from the hosts listed here.
    # If IPv6 support is enabled then '127.0.0.1', '::127.0.0.1', '::ffff:127.0.0.1' are treated equally.
    #
    # Mandatory: no
    # Default:
    # Server=
    # Server=IP地址或主机名,建议IP地址
    # 说明:在有二级代理情况下,此IP地址应该填写二级代理服务器的IP,反之,若无二级代理服务器,则此IP应设置为服务端IP

    Server=127.0.0.1

    ### Option: ListenPort
    # Agent will listen on this port for connections from the server.
    #
    # Mandatory: no
    # Range: 1024-32767 (监控端口范围)
    # Default:
    # ListenPort=10050
    # ListenPort=数字
    # 说明:此AGENT端以本地服务的形式运行,需要监听端口,强烈建议设置为10050,以便移动整个系统统一规划管理,当然,特殊情况下可修改为1024-32767 未使用的端口

    ### Option: ListenIP
    # List of comma delimited IP addresses that the agent should listen on.
    # First IP address is sent to Zabbix server if connecting to it to retrieve list of active checks.
    #
    # Mandatory: no
    # Default:
    # ListenIP=0.0.0.0
    # ListenIP=IP地址
    # 说明:对应的ListenPort监听到哪个IP上面,建议指定IP时,不用0.0.0.0

    ### Option: StartAgents
    # Number of pre-forked instances of zabbix_agentd that process passive checks.
    # If set to 0, disables passive checks and the agent will not listen on any TCP port.
    #
    # Mandatory: no
    # Range: 0-100 数字范围(0-100)
    # Default:
    # StartAgents=3
    # StartAgents=数字
    # 说明:在被动模式下,此参数用于设置控制监听进程可启用的子进程的数量,若监控项较多且采集很频繁,建议加大此数值;
    # 若此数值为0,则禁止使用被动模式。另外,一般情况,不建议修改此数值,当且仅当某些监控项无法采集到数据,或数据采集数据有延迟现象时,可调整。第四,启用线程越多,则相对越耗系统资源

    ##### Active checks related
    # 主动模式相关参数设置
    # 什么时主动模式?
    # 在主动模式下,AGENT端(即采集客户端)将所采集的结果,主动提交给二级代理服务器或服务器,而此种情况下,二级代理服务器或服务器将被动接收采集信息

    ### Option: ServerActive
    # List of comma delimited IP:port (or hostname:port) pairs of Zabbix servers for active checks.
    # If port is not specified, default port is used.
    # IPv6 addresses must be enclosed in square brackets if port for that host is specified.
    # If port is not specified, square brackets for IPv6 addresses are optional.
    # If this parameter is not specified, active checks are disabled.
    # Example: ServerActive=127.0.0.1:20051,zabbix.domain,[::1]:30051,::1,[12fc::1]
    #
    # Mandatory: no
    # Default:
    # ServerActive=
    # ServerActive=IP地址或IP地址:端口号
    # 说明:在主动模式下,ServerActive为二级代理服务器或服务器,默认端口为10051,若需更改端口,则为#ServerActive=IP:port,非特殊情况下,不建议修改。

    ServerActive=127.0.0.1

    ### Option: Hostname
    # Unique, case sensitive hostname.
    # Required for active checks and must match hostname as configured on the server.
    # Value is acquired from HostnameItem if undefined.
    #
    # Mandatory: no
    # Default:
    # Hostname=
    # Hostname=主机名
    # 说明:手工自定义一个主机名,可以和系统的主机名一样,也可以不一样,此参数可根据实际情况启用或关闭,建议关闭此参数,并启用HostnameItem参数

    Hostname=Zabbix server

    ### Option: HostnameItem
    # Item used for generating Hostname if it is undefined. Ignored if Hostname is defined.
    # Does not support UserParameters or aliases.
    #
    # Mandatory: no
    # Default:
    # HostnameItem=system.hostname
    # HostnameItem:自动获取主机名
    # 说明:system.hostname是ZABBIX内置的一个自动获取主机名的方法,为了方便配置,建议打开此参数而关闭Hostname参数#。注意:HostnameItem的优化级低于Hostname,当两个参数都启用且配置的情况下,ZABBIX获取的主机名,将以Hostname为#准

    ### Option: HostMetadata
    # Optional parameter that defines host metadata.
    # Host metadata is used at host auto-registration process.
    # An agent will issue an error and not start if the value is over limit of 255 characters.
    # If not defined, value will be acquired from HostMetadataItem.
    #
    # Mandatory: no
    # Range: 0-255 characters 0-255个字符
    # Default:
    # HostMetadata=
    # HostMetadata=字符串
    # 说明:用于定义当前主机唯一标识符,最大长度255个,仅适用于自动发现情况下,默认不定义,建议不定义

    ### Option: HostMetadataItem
    # Optional parameter that defines an item used for getting host metadata.
    # Host metadata is used at host auto-registration process.
    # During an auto-registration request an agent will log a warning message if
    # the value returned by specified item is over limit of 255 characters.
    # This option is only used when HostMetadata is not defined.
    #
    # Mandatory: no
    # Default:
    # HostMetadataItem=
    # 说明;用于获取主机的HostMetadata,建议保持默认

    ### Option: RefreshActiveChecks
    # How often list of active checks is refreshed, in seconds.
    #
    # Mandatory: no
    # Range: 60-3600
    # Default:
    # RefreshActiveChecks=120
    # RefreshActiveChecks=数字
    # 说明:被监控的主机多久(秒)重新请求二级代理或服务端刷新一监控列表。范围为60-3600秒。ZABBIX运行原理为:,zabbix客户端启动后,在等待RefreshActiveChecks秒后,开始从二级代理或服务端请求并下载监控项信息,保存在本地专门的buffersend中,再过RefreshActiveChecks秒后,重新获取监控项信息。这就是为什么当配置监控项,要过一会才能生效的原因。这个数值,就是等待时间。建议,不要将此数值设置过小,以免加大AGENT端和服务端及数据库的压力,建议为120秒。

    ### Option: BufferSend
    # Do not keep data longer than N seconds in buffer.
    #
    # Mandatory: no
    # Range: 1-3600
    # Default:
    # BufferSend=5
    # BufferSend=数字
    # 说明:多少秒后,将BUFFER中的数据提交到二级代理或服务端。范围(1-36600)此数值的大小决定了采集后,提交数据的及时性,数值越小,则提交得越频繁,对服务器压力越大,同时对AGENT端系统资源消耗越大,则表现出来的现象是报警非常及时,建议根据实际情况自行考虑,也可保持默认,若发现ZABBIX消耗资源较多,建议加大此数值。

    ### Option: BufferSize
    # Maximum number of values in a memory buffer. The agent will send
    # all collected data to Zabbix Server or Proxy if the buffer is full.
    #
    # Mandatory: no
    # Range: 2-65535
    # Default:
    # BufferSize=100
    # BufferSize=数值
    # 说明:此参数作用设置保存采集数据在内存中的容量大小。若此agent端监控项较多,建议加大此数值。BufferSize与BufferSend之间有联系的。当达到bUFFERSEND或Buffersize已满时,都会触发数据提交动作。

    ### Option: MaxLinesPerSecond
    # Maximum number of new lines the agent will send per second to Zabbix Server
    # or Proxy processing 'log' and 'logrt' active checks.
    # The provided value will be overridden by the parameter 'maxlines',
    # provided in 'log' or 'logrt' item keys.
    #
    # Mandatory: no
    # Range: 1-1000
    # Default:
    # MaxLinesPerSecond=100
    # MaxLinesPerSecond=数值
    # 说明:定义了AGENT在1秒内发送的日志行数,用于避免网络或cpu过载,建议保持默认

    ############ ADVANCED PARAMETERS #################
    # 高级参数设置

    ### Option: Alias
    # Sets an alias for an item key. It can be used to substitute long and complex item key with a smaller and simpler one.
    # Multiple Alias parameters may be present. Multiple parameters with the same Alias key are not allowed.
    # Different Alias keys may reference the same item key.
    # For example, to retrieve the ID of user 'zabbix':
    # Alias=zabbix.userid:vfs.file.regexp[/etc/passwd,^zabbix:.:([0-9]+),,,,1]
    # Now shorthand key zabbix.userid may be used to retrieve data.
    # Aliases can be used in HostMetadataItem but not in HostnameItem parameters.
    #
    # Mandatory: no
    # Range:
    # Default:
    # 设置参数的别名。它可以替代长和复杂的一个小而简单的一个有用的参数名称

    ### Option: Timeout
    # Spend no more than Timeout seconds on processing
    #
    # Mandatory: no
    # Range: 1-30
    # Default:
    # Timeout=3
    # Timeout=数值
    # 说明:当agent采集一个数据时,多长少算超时。建议保持默认

    ### Option: AllowRoot
    # Allow the agent to run as 'root'. If disabled and the agent is started by 'root', the agent
    # will try to switch to user 'zabbix' instead. Has no effect if started under a regular user.
    # 0 - do not allow
    # 1 - allow
    #
    # Mandatory: no
    # Default:
    # AllowRoot=0
    # AllowRoot=0或1
    # 说明:是否允许ROOT帐号运行此客户端。0:不允许,1:允许,当一个脚本执行需要以ROOT身份执行的,则此开关必须打开,建议根据实际情况开启或关闭,

    ### Option: Include
    # You may include individual files or all files in a directory in the configuration file.
    # Installing Zabbix will create include directory in /etc/zabbix, unless modified during the compile time.
    #
    # Mandatory: no
    # Default:
    # Include=
    # Include=目录路径或扩展配置文件路径
    # 说明:从配置文件可管理性或扩展性考虑,若需配置大量参数的且为了方便后续管理可以启用此参数,建议根据实际情况考虑,不过,一般情况下无须启用
    # Include=/etc/zabbix/zabbix_agentd.userparams.conf
    # Include=/etc/zabbix/zabbix_agentd.conf.d/
    Include=/etc/zabbix/zabbix_agentd.conf.d/

    ####### USER-DEFINED MONITORED PARAMETERS #######
    # 自定义监控脚本

    ### Option: UnsafeUserParameters
    # Allow all characters to be passed in arguments to user-defined parameters.
    # 0 - do not allow
    # 1 - allow
    #
    # Mandatory: no
    # Range: 0-1
    # Default:
    # UnsafeUserParameters=0
    # UnsafeUserParameters=0或1
    # 说明:是否启用用户自定义监控脚本,1启用,0不启用。由于ZABBIX实现监控方法的多样性,一般都采用脚本来实现监控数据的采集,所以,建议开启,否则功能将受限。

    ### Option: UserParameter
    # User-defined parameter to monitor. There can be several user-defined parameters.
    # Format: UserParameter=<key>,<shell command>
    # See 'zabbix_agentd' directory for examples.
    #
    # Mandatory: no
    # Default:
    # UserParameter=

    ####### LOADABLE MODULES #######

    ### Option: LoadModulePath
    # Full path to location of agent modules.
    # Default depends on compilation options.
    #
    # Mandatory: no
    # Default:
    # LoadModulePath=${libdir}/modules
    # 说明:扩展模块路径,强烈建议不要改动,除非你具有AGENT 开发能力

    ### Option: LoadModule
    # Module to load at agent startup. Modules are used to extend functionality of the agent.
    # Format: LoadModule=<module.so>
    # The modules must be located in directory specified by LoadModulePath.
    # It is allowed to include multiple LoadModule parameters.
    #
    # Mandatory: no
    # Default:
    # LoadModule=
    # 说明:扩展模块路径,强烈建议不要改动,除非你具有AGENT 开发能力

    # UserParameter=
    # 说明:用户自定义监控脚本,当且仅当UnsafeUserParameters=1时UserParameter生效。以下为SNC初始自定监控脚本,不建议修改,已有选项,但可自义添加。
    # 自定义监控项配置语法
    # UserParameter=key,command
    # 如何使用:以获取mysql监控为例
    # 步骤1,设置自定义脚本
    # UserParameter=mysql.questions,mysqladmin -uroot --password='XXXXX' status|cut -f4 -d":"|cut -f1 -d"S"
    # 保存退出,并重启AGENT
    # 步骤2,手工验证
    # 在二级代理端或服务器端用命令 zabbix_get -s IP -k mysql.questions 将返回采集信息
    # 步骤3,在管理页面添加监控项
    # 注意:成功关键,脚本本身具有可执行权限,且脚本运行正常
