You have an error somewhere, either permissions or configuration. You
haven't provided enough information to tell which and I'm not familiar
with the check_netsnmp plugin. Where did you get it? It might be sending
output to STDERR. Try redirecting that in your command definition --

define command{	
	command_name ...
	command_line $USER1$/check_netsnmp -H $HOSTADDRESS$ -d disk 2>&1
}

99.9999999% chance it's not.
