4 Zabbix agent (Windows)

The parameters supported in a Zabbix agent (Windows) configuration file:

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.
For example, to retrieve paging file usage in percents from the server:
Alias=pg_usage:perf_counter[\Paging File(_Total)\% Usage]
Now shorthand key pg_usage may be used to retrieve data.
Aliases can be used in HostMetadataItem but not in HostnameItem or PerfCounter parameters.
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 Zabbix server or proxy if the buffer is full.
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 (Currently, same as level 4. Can be set only using runtime control options.)
EnableRemoteCommands no 0 Whether remote commands from Zabbix server are allowed.
0 - not allowed
1 - allowed
HostMetadata no 0-255 characters Optional parameter that defines host metadata. Host metadata is used only at host auto-registration 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.
This option is supported in version 2.2.0 and higher.
HostMetadataItem no Optional parameter that defines a Zabbix agent item used for getting host metadata. This option is only used when HostMetadata is not defined.
Supports UserParameters, performance counters and aliases. Supports[] regardless of EnableRemoteCommands value.
Host metadata is used only at host auto-registration process (active agent).
During an auto-registration 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.
This option is supported in version 2.2.0 and higher.
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: 64
HostnameItem no system.hostname Optional parameter that defines a Zabbix 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[] regardless of EnableRemoteCommands value.
This option is supported in version 1.8.6 and higher.
See also a more detailed description.
Include no You may include individual files or all files in a directory in the configuration file.
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. Pattern matching is supported since Zabbix 2.4.0.
See special notes about limitations.
ListenIP no List of comma-delimited IP addresses that the agent should listen on.
Multiple IP addresses are supported since Zabbix 1.8.3.
ListenPort no 1024-32767 10050 Agent will listen on this port for connections from the server.
LogFile no Name of log file.
If not set, Windows Event Log is used.
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.
LogRemoteCommands no 0 Enable logging of executed shell commands as warnings.
0 - disabled
1 - enabled
MaxLinesPerSecond no 1-1000 100 Maximum number of new lines the agent will send per second to Zabbix server
or proxy processing 'log', 'logrt' and 'eventlog' active checks.
The provided value will be overridden by the parameter 'maxlines',
provided in 'log', 'logrt' or 'eventlog' item keys.
PerfCounter no Syntax: <parameter_name>,"<perf_counter_path>",<period>
Defines new parameter <parameter_name> which is an average value for system performance counter <perf_counter_path> for the specified time period <period> (in seconds).
For example, if you wish to receive average number of processor interrupts per second for last minute, you can define new parameter "interrupts" as 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.
RefreshActiveChecks no 60-3600 120 How often list of active checks is refreshed, in seconds.
Note that after failing to refresh active checks the next refresh will be attempted after 60 seconds.
Server no List of comma delimited IP addresses (or hostnames) of Zabbix servers. Spaces are allowed since Zabbix 2.2.
Incoming connections will be accepted only from the hosts listed here.
If IPv6 support is enabled then '', '::', '::ffff:' are treated equally.
ServerActive no (*) IP:port (or hostname:port) of Zabbix server or Zabbix proxy for active checks.
Multiple comma-delimited addresses can be provided to use several independent Zabbix servers in parallel. Spaces are allowed since Zabbix 2.2.
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.
SourceIP no Source IP address for outgoing connections.
StartAgents no 0-63 (*) 3 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.
The upper limit used to be 16 before version 1.8.5.
Timeout no 1-30 3 Spend no more than Timeout seconds on processing
UnsafeUserParameters no 0-1 0 Allow all characters to be passed in arguments to user-defined parameters.
0 - do not allow
1 - allow
UserParameter User-defined parameter to monitor. There can be several user-defined parameters.
Format: UserParameter=<key>,<shell command>
Note that shell command must not return empty string or EOL only.
Example: UserParameter=system.test,echo 1

(*) The number of active servers listed in ServerActive plus the number of pre-forked instances for passive checks specified in StartAgents must be less than 64.

In Zabbix agent 2.0.0 version configuration parameters related to active and passive checks have been changed.
See the "See also" section at the bottom of this page to read more details about these changes.

Zabbix supports configuration files only in UTF-8 encoding without BOM.

Comments starting with "#" are only supported in the beginning of the line.
