Query Explanation

The rule calculates the 5‑minute per‑second rate of spans accepted by the OTLP receiver (otelcol_receiver_accepted_spans) and the rate of spans refused (otelcol_receiver_refused_spans). It fires when the accepted‑span rate is 0 and the refused‑span rate is greater than 0, meaning the OTLP receiver is up but rejecting all incoming spans.
