I am using PRTG version 126.96.36.19934+, with around 30 sensors. We have 3 sensors reading temperature in Server room.
These sensors are installed inside, in the office, the temperature is always above zero. Even more, the temperature in server room is always between 15 C and 30-35 C (which means it's critical)
Unfortunately the gauge displays value between 0 C and maximum value ever reached.
The problem is that the minimum value for the gauge is 0 (zero). Which was never reached and will never be. And the entire area of the gauge covers around 30 degrees Celcius, half of which is never used by the pointer - as all fluctuations of the temperature are between 15 and 30 C.
As a result, the pointer of the gauge moves around very small sector, and it is not very representative.
My question: Is it possible for such a gauge to set the minimum value to 15 Celcius, for example, and let the maximum value come from historical data (or whatever)?
If so, it will result in displaying sector with ONLY POSSIBLE values which will give more visual feedback to the monitoring user.
I have read about Spike filter parameter, but it works only for graphs, not for gauges apparently. The channel values do not seem to affect the minimum value too.
Is there any way to solve that?
Thanks in advance, Vlad
