Nagios showing host state down

Hello Team,

I just have to configure ping monitoring through Nagios for a Windows server. We simply added the hostname and IP address and configured it.
The host is actually UP but Nagios is showing its state as DOWN. It is not able to ping the host.

We have already configured a number of servers for ping monitoring in the same way we did for this server but all worked fine.

I am attaching the screen shot here, please look into it and help us on the same.

Hostname: EU2BWBW036
IP: 10.148.183.229

Note: We do not select any check_command for ping monitoring. I am mentioning this as note here because I have seen other posts on Nagios forum where people select some or the other command.
I have never selected any check_command and it works completely fine.

Also, I have installed NSC++ client on it and other services are running fine, all services are in GREEN state.

Can you ping this host from the Nagios XI server?

Code: Select all

ping 10.148.183.229
If not it is likely a networking or firewall issue

Not able to ping the host from Nagios server.
So that is the problem, Nagios is trying to perform a ping check but it is not getting a response from that server.

I would suggest talking to the network or firewall teams.
