12 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
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:
| Macro | Description |
|---|---|
| {#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”. |
