Hi Chris,
The Collector collects two values of each metric every 5min...and avg and a max value for the metric.
It is this max value that is used to set the 100% of the Network Util.
Example:
Lets say a max value of 200 is collected. Thus if the next avg is 50 then the util is 25% (50 is 25% of 200)
Let say the next avg value collected is 300. Then the Util will be 150% and the new max value is set to 300.
Next collection the avg is 50 again...so now the util is 16.6%
The same for disk IO is valid.
