Thank you Timo!
1. Please, if you are a Peassler employee - please ask for someone to create and official and public KB for this, or elaborate about this in the sensor's details description article.
2. Let me see if I got this correctly for the sensor of "Cloud HTTP v2":
HTTP Response Code:
Basically it is the numeric well-known HTTP response code (e.g. 200 = OK)
In "Live Data" it shows on the graph the actual numeric value
In X days sections it turns to be a percent (%) value and it simply shows a value of zero (0%) constantly, as if it does not calculate any trend of this value, as there is no meaning for doing so for numbers that represent very different things.
So, since this attribute is not relevant in X days sections - better either remove it entirely in these sections, or show it but disable it and mark it as "N/A" and don't show it on the graph.
PRTG Cloud Response:
A simple "On/Good/Working" or "Off/Bad/NotWorking" mark.
In "Live Data" is shows either 1 (Working) or 0 (Not working) and in X days sections it shows these numeric values in percentage over time, between 100%, Working, to below that for non-working times
Is it so?
