14 Discovery of host interfaces in Zabbix

Overview

It is possible to discover all interfaces configured in Zabbix frontend for a host.

Item key

The item to use in the discovery rule is the

zabbix[host,discovery,interfaces]

internal item. This item is supported since Zabbix server 3.4.

This item returns a JSON with the description of interfaces, including:

• IP address/DNS hostname (depending on the “Connect to” host setting)
• Port number
• Interface type (Zabbix agent, SNMP, JMX, IPMI)
• If it is the default interface or not
• If the bulk request feature is enabled - for SNMP interfaces only.

For example:

[{"{#IF.CONN}":"192.168.3.1","{#IF.IP}":"192.168.3.1","{#IF.DNS}":"","{#IF.PORT}":"10050","{#IF.TYPE}":"AGENT","{#IF.DEFAULT}":1}]

With multiple interfaces their records in JSON are ordered by:

• Interface type,
• Default - the default interface is put before non-default interfaces,
• Interface ID (in ascending order).

Supported macros

The following macros are supported for use in the discovery rule filter and prototypes of items, triggers and graphs:
