[root@check3 zabbix]# vim /etc/zabbix/zabbix_agentd.conf # This is a configuration file for Zabbix agent daemon (Unix) # To get more information about Zabbix, visit http://www.zabbix.com ############ GENERAL PARAMETERS ################# ### Option: PidFile # Name of PID file. # # Mandatory: no # Default: # PidFile=/tmp/zabbix_agentd.pid PidFile=/var/run/zabbix/zabbix_agentd.pid #指定程序PID文件的路径，可修改到其他路径，但SNC不建议修改 ### Option: LogType # Specifies where log messages are written to: # system - syslog # file - file specified with LogFile parameter # console - standard output # # Mandatory: no # Default: # LogType=file #客户端agent运行产生的日志文件路径，可修改到其他路径 ### Option: LogFile # Log file name for LogType 'file' parameter. # # Mandatory: no # Default: # LogFile= LogFile=/var/log/zabbix/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=0 #agent产生的日志大小控制，默认为1M，若为0，则表示不产生任何日志，数字范围（1-1024） ### Option: DebugLevel # Specifies debug level: # 0 - basic information about starting and stopping of Zabbix processes #无日志级别 # 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 # 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 #配置0/1 在执行远程命令时是否保存日志，建议产生日志，以便日后查证 ##### 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 # 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= #从配置文件可管理性或扩展性考虑，若需要配置大量参数，且为了日后方便管理可以启用此参数，建议根据实际情况，不过，一般情况下无需启用 Include=/etc/zabbix/zabbix_agentd.d/*.conf # Include=/usr/local/etc/zabbix_agentd.userparams.conf # Include=/usr/local/etc/zabbix_agentd.conf.d/ # Include=/usr/local/etc/zabbix_agentd.conf.d/*.conf ####### 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. # The following characters are not allowed: # \ ' " ` * ? [ ] { } ~ $ ! & ; ( ) < > | # @ # Additionally, newline characters are not allowed. # 0 - do not allow # 1 - allow # # Mandatory: no # Range: 0-1 # Default: # UnsafeUserParameters=0 #是否启用自定义监控脚本，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= #用户自定义脚本，当UnsafeUserParamenters=1时UserParamenter生效，以下为SNC初始自定义监控脚本，不建议，已有选项，但可自定义添加 ####### LOADABLE MODULES ####### ### Option: LoadModulePath # Full path to location of agent modules. # Default depends on compilation options. # # Mandatory: no # Default: # LoadModulePath=${libdir}/modules #扩展模块路径，强烈建议不要动，除非你具有agent开发的能力 ### 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= #强烈建议不动，除非你会agent的开发 ####### TLS-RELATED PARAMETERS ####### ### Option: TLSConnect # How the agent should connect to server or proxy. Used for active checks. # Only one value can be specified: # unencrypted - connect without encryption # psk - connect using TLS and a pre-shared key # cert - connect using TLS and a certificate # # Mandatory: yes, if TLS certificate or PSK parameters are defined (even for 'unencrypted' connection) # Default: # TLSConnect=unencrypted ### Option: TLSAccept # What incoming connections to accept. # Multiple values can be specified, separated by comma: # unencrypted - accept connections without encryption # psk - accept connections secured with TLS and a pre-shared key # cert - accept connections secured with TLS and a certificate # # Mandatory: yes, if TLS certificate or PSK parameters are defined (even for 'unencrypted' connection) # Default: # TLSAccept=unencrypted ### Option: TLSCAFile # Full pathname of a file containing the top-level CA(s) certificates for # peer certificate verification. # # Mandatory: no # Default: # TLSCAFile= ### Option: TLSCRLFile # Full pathname of a file containing revoked certificates. # # Mandatory: no # Default: # TLSCRLFile= ### Option: TLSServerCertIssuer # Allowed server certificate issuer. # # Mandatory: no # Default: # TLSServerCertIssuer= ### Option: TLSServerCertSubject # Allowed server certificate subject. # # Mandatory: no # Default: # TLSServerCertSubject= ### Option: TLSCertFile # Full pathname of a file containing the agent certificate or certificate chain. # # Mandatory: no # Default: # TLSCertFile= ### Option: TLSKeyFile # Full pathname of a file containing the agent private key. # # Mandatory: no # Default: # TLSKeyFile= ### Option: TLSPSKIdentity # Unique, case sensitive string used to identify the pre-shared key. # # Mandatory: no # Default: # TLSPSKIdentity= ### Option: TLSPSKFile # Full pathname of a file containing the pre-shared key. # # Mandatory: no # Default: # TLSPSKFile=
