6 Zabbix agent 2 (Windows)

Overview

Zabbix agent 2 is a new generation of Zabbix agent and may be used in place of Zabbix agent.

This section lists parameters supported in a Zabbix agent 2 configuration file (zabbix_agent2.win.conf). Note that:

  • The default values reflect process defaults, not the values in the shipped configuration files;
  • Zabbix supports configuration files only in UTF-8 encoding without BOM;
  • Comments starting with "#" are only supported in the beginning of the line.

Parameters

Parameter Mandatory Range Default Description
Alias no 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 allowed.
Different Alias keys may reference the same item key.
Aliases can be used in HostMetadataItem but not in HostnameItem parameters.

Examples:

1. Retrieving 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.

2. Getting CPU utilization with default and custom parameters.
Alias=cpu.util:system.cpu.util
Alias=cpu.util[*]:system.cpu.util[*]
This allows use cpu.util key to get CPU utilization percentage with default parameters as well as use cpu.util[all, idle, avg15] to get specific data about CPU utilization.

3. Running multiple low-level discovery rules processing the same discovery items.
Alias=vfs.fs.discovery[*]:vfs.fs.discovery
Now it is possible to set up several discovery rules using vfs.fs.discovery with different parameters for each rule, e.g., vfs.fs.discovery[foo], vfs.fs.discovery[bar], etc.
AllowKey no Allow execution of those item keys that match a pattern. Key pattern is a wildcard expression that supports "*" character to match any number of any characters.
Multiple key matching rules may be defined in combination with DenyKey. The parameters are processed one by one according to their appearance order.
This parameter is supported since Zabbix 5.0.0.
See also: Restricting agent checks.
BufferSend no 1-3600 5 The time interval in seconds which determines how often values are sent from the buffer to Zabbix server.
Note, that if the buffer is full, the data will be sent sooner.
BufferSize no 2-65535 100 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.
This parameter should only be used if persistent buffer is disabled (EnablePersistentBuffer=0).
ControlSocket no \\.\pipe\agent.sock The control socket, used to send runtime commands with '-R' option.
DebugLevel no 0-5 3 Specifies debug level:
0 - basic information about starting and stopping of Zabbix processes
1 - critical information
2 - error information
3 - warnings
4 - for debugging (produces lots of information)
5 - extended debugging (produces even more information)
DenyKey no Deny execution of those item keys that match a pattern. Key pattern is a wildcard expression that supports "*" character to match any number of any characters.
Multiple key matching rules may be defined in combination with AllowKey. The parameters are processed one by one according to their appearance order.
This parameter is supported since Zabbix 5.0.0.
See also: Restricting agent checks.
EnablePersistentBuffer no 0-1 0 Enable usage of local persistent storage for active items.
0 - disabled
1 - enabled
If persistent storage is disabled, the memory buffer will be used.
HostInterface no 0-255 characters Optional parameter that defines host interface.
Host interface is used at host autoregistration process.
An agent will issue an error and not start if the value is over the limit of 255 characters.
If not defined, value will be acquired from HostInterfaceItem.
Supported since Zabbix 4.4.0.
HostInterfaceItem no Optional parameter that defines an item used for getting host interface.
Host interface is used at host autoregistration process.
During an autoregistration 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 HostInterface is not defined.
Supported since Zabbix 4.4.0.
HostMetadata no 0-255 characters Optional parameter that defines host metadata. Host metadata is used at host autoregistration process.
An agent will issue an error and not start if the specified value is over the limit or a non-UTF-8 string.
If not defined, the value will be acquired from HostMetadataItem.
HostMetadataItem no Optional parameter that defines an item used for getting host metadata. Host metadata item value is retrieved on each autoregistration attempt for host autoregistration process.
During an autoregistration request an agent will log a warning message if the value returned by the specified item is over the limit of 255 characters.
This option is only used when HostMetadata is not defined.
Supports UserParameters and aliases. Supports system.run[] regardless of EnableRemoteCommands value.
The value returned by the item must be a UTF-8 string otherwise it will be ignored.
Hostname no set by HostnameItem Unique, case sensitive hostname.
Required for active checks and must match hostname as configured on the server.
Allowed characters: alphanumeric, '.', ' ', '_' and '-'.
Maximum length: 128
HostnameItem no system.hostname Item used for generating Hostname if it is not defined. Ignored if Hostname is defined.
Does not support UserParameters or aliases, but does support system.run[] regardless of EnableRemoteCommands value.
Include no You may include individual files or all files in a directory in the configuration file.
During installation Zabbix will create the include directory in /usr/local/etc, unless modified during the compile time.
To only include relevant files in the specified directory, the asterisk wildcard character is supported for pattern matching. For example: /absolute/path/to/config/files/*.conf.
See special notes about limitations.
ListenIP no 0.0.0.0 List of comma-delimited IP addresses that the agent should listen on.
The first IP address is sent to Zabbix server, if connecting to it, to retrieve the list of active checks.
ListenPort no 1024-32767 10050 Agent will listen on this port for connections from the server.
LogFile yes, if LogType is set to file, otherwise
no
c:\zabbix_agent2.log Log file name if LogType is 'file'.
LogFileSize no 0-1024 1 Maximum size of log file in MB.
0 - disable automatic log rotation.
Note: If the log file size limit is reached and file rotation fails, for whatever reason, the existing log file is truncated and started anew.
LogType no file Specifies where log messages are written to:
system - syslog,
file - file specified by LogFile parameter,
console - standard output.
PersistentBufferFile no The file, where Zabbix Agent2 should keep SQLite database.
Must be a full filename.
This parameter is only used if persistent buffer is enabled (EnablePersistentBuffer=1).
PersistentBufferPeriod no 1m-365d 1h The time period for which data should be stored, when there is no connection to the server or proxy. Older data will be lost. Log data will be preserved.
This parameter is only used if persistent buffer is enabled (EnablePersistentBuffer=1).
