Query Explanation

The query calculates the per‑second rate of the metric otelcol_receiver_refused_spans over the last 5 minutes; if this rate is greater than zero (i.e., any spans were refused) for a given receiver label, the alert fires. Thus, the alert triggers whenever the OpenTelemetry Collector has refused at least one span on the specified receiver within the recent 5‑minute window.
