Check_service not working as expected

Hello guys,

I've wrote the script on my server. Manually i get the status of the service.
But somehow when i put it in a script that manage all my monitoring in my server, it doesnt work. In nagios, says Connection refused. but everything its alright.
There is a way to make it that check an specific service. without writing the options -o -s?

like check_service, that check httpd or sshd or mysqld.
