Notification problem

My intention is to monitor https url and if the url down send alert to me . I already create user , contact group and other necessary

check_tcp from command.cfg is

command_line $USER1$/check_tcp -H $HOSTADDRESS$ -p $ARG1$ $ARG2$

my check command is

check_command check_http!443

I can see status and result of the command but I don’t have any notification from the service

IF I use this

my check command is

check_command check_http!

I can get status , result and notification also . can anyone explain me why … :roll:
