The default graph options in PRTG (Setup > System Administration > User Interface) for extended periods of time (e.g. over 10 days) will display the average over a set period (e.g. 1 hour) – while this may be ideal for some data on occasion you may want to display the maximum or minimum value for the data over that period.
The example below shows just how much this can change the graphical representation of the data with the ‘max’ value when averaged as 48% while this climbs all the way to 53% when the graph purely displays the maximum values.
It’s the same data but the top graph shows a 1 hour average whereas the bottom graph shows the 1 hour maximum.
To change this display of data hop into the channel settings for the sensor and follow the screenshot guide below:
