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

  1. 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:

  1. [{"{#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:

MacroDescription
{#IF.CONN}Interface IP address or DNS host name.
{#IF.IP}Interface IP address.
{#IF.DNS}Interface DNS host name.
{#IF.PORT}Interface port number.
{#IF.TYPE}Interface type (“AGENT”, “SNMP”, “JMX”, or “IPMI”).
{#IF.DEFAULT}Default status for the interface:
0 - not default interface
1 - default interface
{#IF.SNMP.BULK}SNMP bulk processing status for the interface:
0 - disabled
1 - enabled
This macro is returned only if interface type is “SNMP”.
