5 Áú»¢¶Ä²© agent (Windows)
Overview
This section lists parameters supported in a Áú»¢¶Ä²© agent (Windows) configuration file (zabbix_agentd.conf).
Note that:
- The default values reflect daemon defaults, not the values in the shipped configuration files;
- Áú»¢¶Ä²© supports configuration files only in UTF-8 encoding without ;
- 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 paging file usage in percentage from the server. Alias=pg_usage:perf_counter[File(_Total)% Usage] Now the shorthand key pg_usage may be used to retrieve data. 2. Getting CPU load with default and custom parameters. Alias=cpu.load:system.cpu.load Alias=cpu.load[*]:system.cpu.load[*] This allows use cpu.load key to get the CPU load with default parameters as well as use cpu.load[percpu,avg15] to get specific data about the CPU load. 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 Áú»¢¶Ä²© 5.0.0. See also: Restricting agent checks. |
||
| BufferSend | no | 1-3600 | 5 | Do not keep data longer than N seconds in buffer. |
| BufferSize | no | 2-65535 | 100 | Maximum number of values in a memory buffer. The agent will send all collected data to Áú»¢¶Ä²© server or proxy if the buffer is full. |
| DebugLevel | no | 0-5 | 3 | Specifies debug level: 0 - basic information about starting and stopping of Áú»¢¶Ä²© 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 Áú»¢¶Ä²© 5.0.0. See also: Restricting agent checks. |
||
| EnableRemoteCommands | no | 0 | Whether remote commands from Áú»¢¶Ä²© server are allowed. This parameter is deprecated, use AllowKey=system.run[*] or DenyKey=system.run[*] instead It is internal alias for AllowKey/DenyKey parameters depending on value: 0 - DenyKey=system.run[*] 1 - AllowKey=system.run[*]. |
|
| 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 Áú»¢¶Ä²© 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 Áú»¢¶Ä²© 4.4.0. |
||
| HostMetadata | no | 0-255 characters | Optional parameter that defines host metadata. Host metadata is used only at host autoregistration process (active agent). If not defined, the value will be acquired from HostMetadataItem. An agent will issue an error and not start if the specified value is over the limit or a non-UTF-8 string. |
|
| HostMetadataItem | no | Optional parameter that defines a Áú»¢¶Ä²© agent item used for getting host metadata. This option is only used when HostMetadata is not defined. Supports UserParameters, performance counters and aliases. Supports system.run[] regardless of AllowKey/DenyKey value. HostMetadataItem value is retrieved on each autoregistration attempt and is used only at host autoregistration process (active agent). 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. The value returned by the item must be a UTF-8 string otherwise it will be ignored. |
||
| Hostname | no | Set by HostnameItem | List of comma-delimited unique, case-sensitive hostnames. Required for active checks and must match hostnames as configured on the server. Value is acquired from HostnameItem if undefined. Allowed characters: alphanumeric, '.', ' ', '_' and '-'. Maximum length: 128 characters per hostname, 2048 characters for the entire line. |
|
| HostnameItem | no | system.hostname | Optional parameter that defines a Áú»¢¶Ä²© agent item used for getting host name. This option is only used when Hostname is not defined. Does not support UserParameters, performance counters or aliases, but does support system.run[] regardless of AllowKey/DenyKey value. See also a more detailed description. |
|
| Include | no | You may include individual files or all files in a directory in the configuration file (located in C:\Program Files\Áú»¢¶Ä²© Agent by default if Áú»¢¶Ä²© agent is installed using Windows MSI installer packages; located in the folder specified during installation if Áú»¢¶Ä²© agent is installed as a zip archive). All included files must have correct syntax, otherwise agent will not start.To only include relevant files in the specified directory, the asterisk wildcard character is supported for pattern matching. For example: C:\Program Files\Áú»¢¶Ä²© Agent\zabbix_agentd.d\*.conf.See special notes about limitations. |
||
| ListenBacklog | no | 0 - INT_MAX | SOMAXCONN | The maximum number of pending connections in the TCP queue. Default value is a hard-coded constant, which depends on the system.

The provided value will be overridden by the parameter 'maxlines', provided in 'log', 'logrt' or 'eventlog' item keys. Note: Áú»¢¶Ä²© will process 10 times more new lines than set in MaxLinesPerSecond to seek the required string in log items. |
| PerfCounter | no | Defines a new parameter <parameter_name> which is an average value for system performance counter <perf_counter_path> for the specified time period <period> (in seconds). Syntax: <parameter_name>,"<perf_counter_path>",<period> For example, if you wish to receive average number of processor interrupts per second for last minute, you can define a new parameter "interrupts" as the following: PerfCounter = interrupts,"\Processor(0)\Interrupts/sec",60 Please note double quotes around performance counter path. The parameter name (interrupts) is to be used as the item key when creating an item. Samples for calculating average value will be taken every second. You may run "typeperf -qx" to get list of all performance counters available in Windows. |
||
| PerfCounterEn | no | Defines a new parameter <parameter_name> which is an average value for system performance counter <perf_counter_path> for the specified time period <period> (in seconds). Syntax: <parameter_name>,"<perf_counter_path>",<period> Compared to PerfCounter, perfcounter paths must be in English. Supported only on Windows Server 2008/Vista and above. For example, if you wish to receive average number of processor interrupts per second for last minute, you can define a new parameter "interrupts" as the following: PerfCounterEn = interrupts,"\Processor(0)\Interrupts/sec",60 Please note double quotes around performance counter path. The parameter name (interrupts) is to be used as the item key when creating an item. Samples for calculating average value will be taken every second. You can find the list of English strings by viewing the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib\009.This parameter is supported since Áú»¢¶Ä²© 4.0.13 and 4.2.7. |
