The screenshot above shows a portion of the sensor in its default form; in this post I’m going to show how to…
- Remove the red ‘downtime’ line from the bottom of the chart
- Set maximum and minimum values of the graph to display 0 to 100%
- Set the gauge to display its value in GByte instead of MByte
Red Downtime line
Pure aesthetics with this tweak – the memory sensor isn’t something that I would expect to ever encounter downtime (if there server were offline then the PING sensor would pause the memory sensor automatically). The only real application for the downtime sensor would be if WMI wasn’t responding.
Max and Min
PRTG will automatically set the scale for your graphs but I prefer to see the full range of 0 – 100%; this tweak makes that possible.
GByte instead of MByte
When working with servers with small amounts of RAM (lets say 4GB and less) it is typically going to work out best to view free RAM as MBytes but when working with Hyper-V hosts (48GB and 96GB in my case) GBytes are a much better value to work with.
