Yes, and you should also have one for the host that looks like:

Code: Select all

define host {
    host_name ...
    address ...
    ...
}

The likely problem is that using "-I" causes the check to use the IP address which may not work if the IP hosts multiple websites. Change the command to use -H instead:

Code: Select all

define command{
	command_name 	check_http
	command_line	$USER1$/check_http -I $HOSTADDRESS$ $ARG1$
}	

Here its is https://prnt.sc/s0t615

and I have already changed to H from I

The value for host_name appears to have a space "... Server". This needs to be a valid hostname that can resolve to an IP.

You can test the command directly with:

Code: Select all

./check_http -I <hostname>

Code: Select all

/usr/local/nagios/libexec/check_http -I nginx_hostname -v

Modify the host definition so that the address line uses the fqdn instead:

Code: Select all

define host{
use                             linux-box              
host_name                       ... Server                 
alias                           ... Server            
address                         ....com  
}
