AMG Grafana transform calculation problem

0

I'm trying to calculate the sum of 2 data stream values(double) in AMG (sitewise data source/disassociated data stream) and present the calculated result in a timeseries panel. I have attempted to use transform 'Add field from calculation': Using 'Mode' binary operation', operation 'datastream1 + datastream 2' without success. How can I calculate fields in AMG ? Any tips will be welcome!

Hi Jason,

Your issue is likely due to a different time precision in each datastream. Look at the example below.

Note the difference in offsetInNanos for timestamps 1662866820 and 1662866830. When the offset is different in each datastream, Grafana Binary operation returns a NaN.
