In this article we’ll show how to configure ICMP-based network device monitoring using ping in Zabbix. It is the easiest and the most popular task of agentless monitoring, when you want to check the availability of a remote server, website or network device from your monitoring server. Zabbix can send ICMP requests to the host, and if no answer is received, the response time is too long or a large percentage of packets are lost, it displays a warning on the dashboard. The ICMP protocol is mostly used to check the availability of network hosts. Ping and traceroute/tracert tools also work over ICMP protocol.
