Using gauge is probably not appropriate here. Gauge is right where the
value returned using SNMP is what you want to graph (e.g. a temperature)
but in this case the SNMP agent will return the total since the last reset
(or counter overflow) and what you are interested in is the difference
between this number and the number last time you read it.
There will be another issue if the error rate is under 1 per second. You
would need to consider graphing the rate as per minute or even per hour to
get anything significant shown on the graph.
Hope that helps.
