Is there a way to show a change in value over a selected time period? All that interests me is the offset of the last value compared to the original. Values can vary above and below these values over a period of time, this is not very relevant (and would be an exception in my case).
With an initial value of 100 and an end value of 105, I expect that one statistic field will display 5%.
I have the feeling that I'm missing something obvious, but I can’t find a way to show this deceptively simple task.
Edit:
I am trying to create a Grafana toolbar with a script that will automatically add disk consumption growth for all of our different volumes. The data is already in Graphite, but for bandwidth management and financial planning purposes (which projects / departments receive invoices) it would be useful for managers to have a simple and rough overview of what volumes are growing beyond the expected parameters.
The idea was to create a color-coded list of values with the same status, which you can easily scroll to find deviations. Disk utilization will obviously never be negative, but usage volatility between the beginning and the end of the time period will be lost in this view. This is not a big problem for us, because it is all a common repository, and such use is expected to a certain extent.
