I have a sensor (Printer Beta) that tracks pages printed. When I started using PRTG the printer had over 400k pages. At some point however, PRTG recorded 200,000 pages which messes up the graphs. And I'd rather not manually set the X axis as that'll require constant attention over time to maintain as the page count shifts upward. I have the spike filter set to a min of 400k, but the 200k reading remains.
How do I remove this piece of spurious data?
