Configuring a discovery rule

To see how this could work, let's have a simple discovery rule. We can discover our test systems, or we can point the discovery at another network range that is accessible to the Zabbix server.

To create a network discovery rule, execute the following:

1. Navigate to Configuration | Discovery and click on Create discovery rule.
2. Fill in the name and IP range as desired, and then click on New in the Checks block. Choose ICMP ping in the Check type drop-down and click on Add in this block. Additionally, change Delay to 2m so that we can more easily see the effects of any changes:

Make sure fping is properly configured—we did that in Chapter 3, Monitoring with Zabbix Agents and Basic Protocols.

3. When done, click on the Add button at the bottom.
