Measurement schema for cross series query


#1

Hi folks, I’m new about the influxDb world, I’ve been through the documentation on the website but I still don’t figure out how to handle my situation.
I have several measurements that represent different acquisition session, in these measurements there are many series representing the various sensors data (each point has as tag name the name of the sensor and as field the value at that time).
I need to iterate through all the measurements to find if a condition is matched, e.g. find the measurement where the temperature is less than 15 and the humidity is equal to 95.
Do you know how to solve this problem? I’ve tried something but with no success

Thank you

Hell @Bart,

You’ll need to use Flux to perform math across measurements.

Please take a look at those two links to learn how to join your measurements together and then filter on your conditions.

Best,
