Chirpstack v4 Device Link Metrics API

[Ronit_Vairagi]

I am using this API :

http://xxxx/api/devices/xxxxxxxx/link-metrics?aggregation=MINUTE&start=2024-09-16T07:25:00Z&end=2024-09-16T07:55:00Z

For aggregation value “MINUTE” I always get 0 in all of the metrics. Example:

"datasets": [
            {
                "label": "rssi",
                "data": [0, 0, 0, 0, 0, 0]
            }
        ],
        "kind": "ABSOLUTE"

and similar for other metrics as well.

However, whenever I change the aggregation value to “HOUR”, “DAY” etc. I get the correct data values.

Is there something else that we need to do for aggregation minute to get the correct data? Or am I missing something else entirely?
