ICMP (Ping)
The ICMP monitor checks network reachability of hosts using ICMP Echo Request (ping).
How it works
- The system sends an ICMP Echo Request to the specified host
- Waits for an ICMP Echo Reply
- If there is no reply — a notification is sent

Notifications
Here you can specify contact groups for notifications. If left unspecified, the user's email is used.
You can also set a waiting period — Grace Period. It is added to the expected time of the next signal. For example, if the interval is 5 minutes and the Grace Period is 2 minutes, the alert will be sent 7 minutes after the last signal. Repeated notifications remind you of the problem; you can set the interval and number of these reminders.
Limitations
- Some hosts block ICMP traffic at the firewall level
- ICMP does not check service health, only network reachability
- To check specific services use TCP or HTTP monitors
