The short time window in the Requests, Errors, and Latency services for OpenTelemetry RED monitoring has been raised from 1 minute to 5 minutes.
With a 1-minute lookback, most data sources provide only a single data point — too few for accurate rate calculations. Using 5 minutes (at least 4–5× the typical 1-minute emission interval) ensures several data points are always included.
In the background this was worked around by using a implicit 2 minute window. This lead to wrong data if a data source was used that had a less than 1 minute emission period.
The label for this window changes from "Last minute" to "Last 5 minutes" in the service output.
Rulesets that have been used to set a 1 minute limit need to be adopted to account for the new 5 minute time window.
