13 Trapper items

Overview

Trapper items accept incoming data instead of querying for it.

It is useful for any data you might want to “push” into Zabbix.

To use a trapper item you must:

  • have a trapper item set up in Zabbix
  • send in the data into Zabbix

Configuration

Item configuration

To configure a trapper item:

  • Go to: ConfigurationHosts
  • Click on Items in the row of the host
  • Click on Create item
  • Enter parameters of the item in the form

The fields that require specific information for trapper items are:

Type Select Zabbix trapper here.
Key Enter a key that will be used to recognize the item when sending in data.
Type of information Select the type of information that will correspond the format of data that will be sent in.
Allowed hosts If specified, the trapper will accept incoming data only from this comma-delimited list of hosts.
Hosts are identified by IP address/DNS name. For example:
Single IP: 192.168.1.33
List of IP addresses: 192.168.56.5, 192.168.56.6, 192.168.56.7
Single DNS name: testzabbix.zabbix.com
List of DNS names: testzabbix, testzabbix.zabbix.com, testzabbix1.zabbix.com
Spaces and user macros are allowed in this field since Zabbix 2.2.0.

You may have to wait up to 60 seconds after saving the item until the server picks up the changes from a configuration cache update, before you can send in values.

Sending in data

In the simplest of cases, we may use zabbix_sender utility to send the monitoring data for trapper item. If we have sent the value “test value” for our trapper item, here is how it will appear in Monitoring → Latest data:
