You expect something that increases over time and you expect (current_counter-previous_counter)/(current_time-previous_time) to return some number. > $min1 = `/usr/local/bin/snmpget -Ov $ip_address public laLoad.1`; > #$min5 = `/usr/local/bin/snmpget -Ov $ip_address public laLoad.2`; > #$min15 = `/usr/local/bin/snmpget -Ov $ip_address public laLoad.3`; This usually produces a GAUGE. (current_value - previous_value) is near to zero and can even be negative. Dividing it by (current_time - previous_time) makes no sense. I guess this is the part, indeed a fundamental part, you didn't grasp. I suggest you focus on the differences between COUNTER, DERIVE, ABSOLUTE and GAUGE before you continue.
