Nagios Support Forum

Hi, what is the difference between host check and service check (i.e. ping)? How does Nagios measure host rta vs ping rta? Sometimes, I get host flapping warning but the ping rta is normal.

Thank you,

Hello @benardj,

It depends on the check command you are using and the configurations settings. Are you sure you have flap detection enabled on the service?

In many cases, host checks are done using the check_icmp plugin.
