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

### Option: PidFile

# Name of PID file.

#

# Mandatory: no

# Default:

#pidFile=PID路径

#说明:指定agent程序PIDFILE存放路径,可以根据实际情况修改位置,但个人不建议修改。

PidFile=/smp/sncmon/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保存路径,也可根据实际情况修改到其它路径,例如/var/log/zabbix/zabbix_agnetd.log,也可保持默认不变。

LogFile=/smp/sncmon/zabbix_agentd.log

### Option: LogFileSize

# Maximum size of log file in MB.

# 0 – disable automatic log rotation.

#

# Mandatory: no

# Range: 0-1024

# Default:

#LogFileSize=数字

#说明:AGENT产生日志大小控制,默认1M,修改为0表示不产生任何日志,此参数值范围1-1024M,不建议关闭日志功能,建议保持默认状态。

LogFileSize=1

### 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。

#

# Mandatory: no

# Range: 0-4

# Default:

DebugLevel=3

### Option: SourceIP

# Source IP address for outgoing connections.

#

# Mandatory: no

# Default:

#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。

SourceIP=192.168.1.3

### Option: EnableRemoteCommands

# Whether remote commands from Zabbix server are allowed.

# 0 – not allowed 不允许

# 1 – allowed 允许

#

# Mandatory: no

# Default:

#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。但是在设置后要注意安全管理,毕竟是有权限直接执行底层命令的,如果zabbixserver被黑后果不堪设想。

EnableRemoteCommands=1

### 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=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

LogRemoteCommands=1

##### 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=192.168.1.14

### 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=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

ListenPort=10050

### 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=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

# ListenIP=192.168.1.6

### 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=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

StartAgents=5

##### 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=192.168.1.14

### 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.

#

# Mandatory: no

# Default:

#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

HostnameItem=system.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 0-255个字符

# Default:

# 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

# HostMetadata=

### 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:

#说明;用于获取主机的HostMetadata,建议保持默认

# HostMetadataItem=

### Option: RefreshActiveChecks

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

#

# Mandatory: no

# Range: 60-3600

# Default:

#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。

RefreshActiveChecks=120

### Option: BufferSend

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

#

# Mandatory: no

# Range: 1-3600

# Default:

#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。

BufferSend=5

### 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=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。

BufferSize=100

### 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=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

# MaxLinesPerSecond=100

### Option: Alias

# Sets an alias for parameter. It can be useful to substitute long and complex parameter name with a smaller and simpler one.

#

# 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

#alias_name=long_command

### Option: Timeout

# Spend no more than Timeout seconds on processing

#

# Mandatory: no

# Range: 1-30

# Default:

#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

Timeout=30

### 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,

AllowRoot=0

### Option: Include

# You may include individual files or all files in a directory in the configuration file.

# Installing Zabbix will create include directory in /usr/local/etc, 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=/usr/local/etc/zabbix_agentd.userparams.conf

# Include=/usr/local/etc/zabbix_agentd.conf.d/

# 1 – allow

#

# Mandatory: no

# Range: 0-1

# Default:

#UnsafeUserParameters=0或1
