I believe SNMP is a binary protocol, so a simple send/expect may not
work.

You could probably use check_snmp and check for a variable that is used
pretty much everywhere; I use system.sysUpTime.0 (the numeric OID is
1.3.6.1.2.1.1.3.0) in a few places.  Something like:


define command {
	command_name	check_snmp
	command_line	$USER1$/check_snmp -H $HOSTADDRESS$ -C $ARG1$ -w $ARG2$ -c $ARG3$ -o $ARG4$
	}

define service {
	service_description	SNMP uptime
	check_command		check_snmp!community!1:!1:!1.3.6.1.2.1.1.3.0
	...
	}
