How to fetch the measurements from MeasurementRepresentation as returned by the /measurement/measurements/series API which returns the min max values?

What product/components do you use and which version/fix level?

Cumulocity sdk

Are you using a free trial or a product with a customer license?

What are trying to achieve? Please describe in detail.

I am using the MeasurementRepresentation sdk of cumulocity for fetching the measurements. My logic previously was based on fetching the measurements from /measurement/measurements/series API using Java RestTemplate.

Now I am using the measurementrepresentation sdk to fetch the measurements which is returning the response as that of the response from normal /measurement/measurements API. (measurementApi.getMeasurementsByFilter(filter) )

“measurements”: [

How to fetch the measurements as returned by the /measurement/measurements/series API which returns the min max values?

Hi Sethu,

the Java SDK does not support the Series API. You will have to implement this using a REST call yourself. You can take a look at this post as well: Getting Measurement Series using C8y Java SDK

Hi Balpreet,
Oh, I was confident that there is an equivalent sdk representation for series of measurements. Ok no problem, now i have to change my logic to fetch measurements in the java code too.

Thank you for letting me know at the earliest. Appreciate it
