StartAgents
取值范围：0-100
默认值：3
zabbix启动之后开启被动监控的进程数量，如果设置为0，那么zabbix被动监控被禁用，并且不会监听相应端口，也就是说10050端口不会开启。

### 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]

# Value is acquired from HostnameItem if undefined.
#
# Mandatory: no
# Default:
# Hostname=

Hostname
默认值：HostnameItem配置的值
主机名，必须唯一，区分大小写。Hostname必须和zabbix web上配置的一直，否则zabbix主动监控无法正常工作。为什么呢？因为agent拿着这个主机名去问server，我有配置主动监控项 吗？server拿着这个主机名去配置里面查询，然后返回信息。
支持字符：数字字母、’.’、’ ‘、 ‘_’、 ‘-‘，不超过64个字符

### 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
默认值:system.hostname
设置主机名，只有当HostMetadata没设置，她才生效。不支持UserParameters 、aliases，支持system.run[]

### 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=

HostMetadata
取值范围：0-255 字符
仅用于主机自动注册功能，如果当前值为定义，那么它的值默认为HostMetadataItem的值。这个选项在2.2.0之后加入，并且确保支付不能超过限制，以及字符串必须是UTF8，否则服务器无法启动

### 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=

HostMetadataItem
功能同上，如果HostMetadata值未设置，这个配置才有效。支持使用UserParameters、alias、system.run[]

### Option: RefreshActiveChecks
# How often list of active checks is refreshed, in seconds.
#
# Mandatory: no
# Range: 60-3600
# Default:
# RefreshActiveChecks=120

# Mandatory: no
# Range: 2-65535
# Default:
# BufferSize=100

BufferSize
取值范围：2-65535
默认值：100
buffer最大值，如果buffer满了，zabbix将会将检索到的数据发送给zabbix server或者proxy

### 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

MaxLinesPerSecond
取值范围：1-1000
默认值：20
处理监控类型为log何eventlog日志时，agent每秒最大发送的行数。默认为20行

### 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:

Alias
key的别名，例如 Alias=ttlsa.userid:vfs.file.regexp[/etc/passwd,^ttlsa:.:([0-9]+),,,,\1]， 或者ttlsa的用户ID。你可以使用key：vfs.file.regexp[/etc/passwd,^ttlsa:.: ([0-9]+),,,,\1]，也可以使用ttlsa.userid。

备注： 别名不能重复，但是可以有多个alias对应同一个key。

### Option: Timeout
# Spend no more than Timeout seconds on processing
#
# Mandatory: no
# Range: 1-30
# Default:
# Timeout=3

Timeout
默认值：1-30

# 0 - do not allow
# 1 - allow
#
# Mandatory: no
# Default:
# AllowRoot=0
AllowRoot=1

AllowRoot
默认值：0
是否允许使用root身份运行zabbix，如果值为0，并且是在root环境下，zabbix会尝试使用zabbix用户运行，如果不存在会告知zabbix用户不存在。

### Option: User
# Drop privileges to a specific, existing user on the system.
# Only has effect if run as ‘root‘ and AllowRoot is disabled.
