Hi Everyone,
In Nagios XI, I am facing the situation like Host is Down status but all related service is running OK.
Can anyone provide the reason how this is possible?
Much appreciated.
Thanks,
Anand

It would 100% depend on how you specifically configured the checks as well as the plugins being used by your checks.
A scenario: My host checks are using ICMP pings. My service checks are using check_nrpe. My network team begins blocking ICMP requests. My host is "DOWN" because ICMP requests are blocked by the network. My services are "OK" because NRPE over TCP/5666 is not blocked.

mcapra is correct, it really depends on how your checking the host, what command is your host check running?
