not 4 variables, 4 lines.  Per the mrtg-reference doc:
        External Monitoring Scripts
                
                If you want to monitor something which does not provide
                data via snmp you can use some external program to do
                the data gathering.
                
                The external command must return 4 lines of output:
                
                
        Line 1
                
                current state of the first variable, normally 'incoming
                bytes count'
                
        Line 2
                
                current state of the second variable, normally 'outgoing
                bytes count'
                
        Line 3
                
                string (in any human readable format), telling the
                uptime of the target.
                
        Line 4
                
                string, telling the name of the target.
