#	1 - critical information     #灾难信息级别

#	2 - error information    #一般错误级别

#	3 - warnings     #警告级别

#	4 - for debugging (produces lots of information)    #调试级别

#	5 - extended debugging (produces even more information)

#       #说明：0~4级别，日志产生量在相同单位时间，生产的日志量为递增，即0级别日志量最少，4级别最多，默认3级别，建议视具体情况执行把握

# Mandatory: no

# Range: 0-5

# Default:

# DebugLevel=3

### Option: SourceIP

#	Source IP address for outgoing connections.

#

# Mandatory: no

# Default:

# SourceIP=    #当系统设置有多个IP时，需要指定一个IP与二级代理或服务器通信，若系统只有一个IP，也建议指定一个

### Option: EnableRemoteCommands

#	Whether remote commands from Zabbix server are allowed.

#	0 - not allowed

#	1 - allowed

#

# Mandatory: no

# Default:

# EnableRemoteCommands=0    #是否允许本地执行远程命令，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

#	0 - disabled  #不产生日志

#	1 - enabled   #产生日志

#

# Mandatory: no

# Default:

##### 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=127.0.0.1   #在有二级代理时，此处应填二级代理的IP，若没有二级则此处填写服务端IP

### Option: ListenPort

#	Agent will listen on this port for connections from the server.

#

# Mandatory: no

# Range: 1024-32767

# Default:

# ListenPort=10050  #此agent端以本地服务的形式运行，需要监听端口，建议为10050，以便整个系统统一规划，也可以设置为1024-32768之间未使用的端口

### 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  #对应的ListenPort监听到哪个IP上面，建议制定IP，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

# Default:

# StartAgents=3   #在被动模式下，此参数用于设置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，建议加大此值

#此值为0，则禁止使用被动模式，另外一般情况，不建议修改此值，且仅当某些监控项无法采集到数据，或数据采集有延迟现象时可调整，第四，启用线程越多则多系统资源消耗越多

##### Active checks related

### 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=127.0.0.1  #在主动模式下，ServerActive为二级代理服务器或服务端的地址，默认端口10051，若需要更改端口则为IP:port

### 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=   #主机名，手工定义一个主机名，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   #自动获取主机名，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的优先级低于Hostname

### 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

# Default:

# HostMetadata=  #字符串 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，默认不自定义，建议不自定义

### 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=  #用于获取主机的HostMetadata，建议报错默认

### Option: RefreshActiveChecks

#	How often list of active checks is refreshed, in seconds.

#

# Mandatory: no

# Range: 60-3600

# Default:

# RefreshActiveChecks=120  #被监控的主机多久重新请求二级代理或服务端刷新监控列表，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，开始从二级代理服务端请求并下载监控信息，报错在本地专门的buffersend中，再过RefreshActivceChecks秒后，重新获取监控项信息，这就是为什么当配置监控项，要过一会才会生效的原因，这个数字就是等待时间，建议不要将此数字设置过小，以免加大agent端和服务端的压力

### Option: BufferSend

#	Do not keep data longer than N seconds in buffer.

#

# Mandatory: no

# Range: 1-3600

# Default:

# BufferSend=5  #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，此数字的大小决定了采集后，提交数据的及时性，数字越小，则提交的越频繁，对服务器的压力约大，同时对agent端服务器的资源消耗越大，则表现出来的是报警及时

### 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  #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端监控较多，建议加大此数值，bufferSize与BUfferSend之间有联系的，但达到bufferSend或buffersize已满时都会处罚数据提交动作

### 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=20  #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:   #设置参数别名，可以代替复制的一个小而简单的参数名字

### Option: Timeout

#	Spend no more than Timeout seconds on processing

#

# Mandatory: no

# Range: 1-30

# Default:

# Timeout=3  #但agent采集一个数据时，多少算超时，建议报错默认

### 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 the user specified by the User configuration option instead.

#	Has no effect if started under a regular user.

#	0 - do not allow

#	1 - allow

#

# Mandatory: no

# Default:

# AllowRoot=0 #是否允许root账号允许此客户端，0允许，1不允许，但一个脚本需要以root身份执行的时候此设置必须为0

### Option: User

#	Drop privileges to a specific, existing user on the system.

#	Only has effect if run as 'root' and AllowRoot is disabled.

#

# Mandatory: no

# Default:

# User=zabbix

### Option: Include

#	Additionally, newline characters are not allowed.

#	0 - do not allow

#	1 - allow

#

# Mandatory: no

# Range: 0-1

# Default:

### 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.
