A real life scenario

In this example, we would like to set up network discovery for the local network having an IP range of 192.168.1.1-192.168.1.254.

In our scenario we want to:

• discover those hosts that have Zabbix agent running
• run discovery every 10 minutes
• add a host to monitoring if the host uptime is more than 1 hour
• remove hosts if the host downtime is more than 24 hours
• add Linux hosts to the “Linux servers” group
• use the template Linux for Linux hosts
• use the template Windows for Windows hosts

Step 1

Defining a network discovery rule for our IP range.

The rule will be executed every 10 minutes.

When this rule is added, Zabbix will automatically start the discovery and generation of the discovery-based events for further processing.

Step 2

Defining a discovery for adding the discovered Linux servers to the respective group/template.

The action will be activated if:

• the “Zabbix agent” service is “up”
• the value of system.uname (the Zabbix agent key we used in rule definition) contains “Linux”
• Uptime is 1 hour (3600 seconds) or more

• add the discovered host to the “Linux servers” group (and also add host if it wasn’t added previously)
• link host to the Linux template. Zabbix will automatically start monitoring the host using items and triggers from the “Linux” template.

Step 3

Defining a discovery action for adding the discovered Windows servers to the respective group/template.

Step 4

Defining a discovery action for removing lost servers.
