We have a Cisco router that we are monitoring an interface on. The sensor polls every 60 seconds and checks the In/Out speed and the In/Out data volume. What exactly do those figures mean? In other words, is the speed a measurement of the current speed at the time of the poll, or is it an average speed since the last check or is it using Cisco's built in 5 minute average value? Also, if it is measuring the speed at the exact moment of the poll, how would we know if there was a major spike in traffic between the interval of time that we checked? I suppose we would just decrease the interval from 60 seconds to something more like 20 seconds. Is that correct?
