Hello Support,

Just want to understand what is the difference between host alive check in host configuration and ping? I see same command is being run at the background. Can we remove ping monitoring for the devices if the host alive check is already there? Its generating multiple alers for ping as well as host down. I see the host alive check has RTA thresholds quite a big.

check_icmp can check and provide more granular details about a connection than check_ping can:

Some wizards will set up two checks(a host and service check) that rely on check_icmp for both. You can disable the service check in cases like this.
