I have InfluxDB and Grafana setup. I’m collecting temperature data from sensors and showing it in simple line chart.
Now I must add speed of increase/decrease of temperature for the selected period, in °C/minute. The element type in which this is displayed doesn’t really matter, it can be gauge, table etc.
My only solution is to switch to MySQL and calculate in the query, but this approach has it’s downsides.
Can someone suggest solution to this task?
