##### Active checks related

### Option: ServerActive
#	Zabbix server/proxy address or cluster configuration to get active checks from.
#	Server/proxy address is IP address or DNS name and optional port separated by colon.
#	Cluster configuration is one or more server addresses separated by semicolon.
#	Multiple Zabbix servers/clusters and Zabbix proxies can be specified, separated by comma.
#	More than one Zabbix proxy should not be specified from each Zabbix server/cluster.
#	If Zabbix proxy is specified then Zabbix server/cluster for that proxy should not be specified.
#	Multiple comma-delimited addresses can be provided to use several independent Zabbix servers in parallel. Spaces are allowed.
#	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 for Zabbix proxy:
#		ServerActive=127.0.0.1:10051
#	Example for multiple servers:
#		ServerActive=127.0.0.1:20051,zabbix.domain,[::1]:30051,::1,[12fc::1]
#	Example for high availability:
#		ServerActive=zabbix.cluster.node1;zabbix.cluster.node2:20051;zabbix.cluster.node3
#	Example for high availability with two clusters and one server:
#		ServerActive=zabbix.cluster.node1;zabbix.cluster.node2:20051,zabbix.cluster2.node1;zabbix.cluster2.node2,zabbix.domain

# Mandatory: no
# Default:
# ServerActive=

### Option: Hostname
#	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.

### 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 2034 bytes.
#	If not defined, value will be acquired from HostMetadataItem.
#
# Mandatory: no
# Range: 0-2034 bytes
# Default:
# HostMetadata=

HostMetadata=${ZBX_METADATA}

### 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 65535 characters.
#	This option is only used when HostMetadata is not defined.
#
# Mandatory: no
# Default:
# HostMetadataItem=

HostMetadataItem=${ZBX_METADATAITEM}

### Option: HostInterface
#	Optional parameter that defines host interface.
#	Host interface 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 HostInterfaceItem.
#
# Mandatory: no
# Range: 0-255 characters
# Default:
# HostInterface=

HostInterface=${ZBX_HOSTINTERFACE}

### Option: HostInterfaceItem
#	Optional parameter that defines an item used for getting host interface.
#	Host interface 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 HostInterface is not defined.
#
# Mandatory: no
# Default:
# HostInterfaceItem=

HostInterfaceItem=${ZBX_HOSTINTERFACEITEM}

### Option: RefreshActiveChecks
#	How often list of active checks is refreshed, in seconds.
#
# Mandatory: no
# Range: 1-86400
# Default:
# RefreshActiveChecks=5

### Option: BufferSend
#	Do not keep data longer than N seconds in buffer.
#
# Mandatory: no
# Range: 1-3600
# Default:
# BufferSend=5

BufferSend=${ZBX_BUFFERSEND}

### 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

BufferSize=${ZBX_BUFFERSIZE}

### 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
