Host is Down but service running OK-Nagios XI

[akumarhe1868]

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,

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?
