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.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 not 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. The system.run[] item is supported regardless of AllowKey/DenyKey values. 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 (located in C:\Program Files\Zabbix Agent 2 by default if Zabbix agent is installed using Windows MSI installer packages; located in the folder specified during installation if Zabbix agent is installed as a zip archive). All included files must have correct syntax, otherwise agent will not start.The path can be relative to the zabbix_agent2.conf file location (e.g., Include=.\zabbix_agent2.d\plugins.d\*.conf).To only include relevant files in the specified directory, the asterisk wildcard character is supported for pattern matching. For example: C:\Program Files\Zabbix Agent2\zabbix_agent2.d\*.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. |

| 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: 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). |
