Query Explanation

The rule calculates the per‑second rate over the past 5 minutes of the metric otelcol_processor_refused_spans for each processor, and if that rate is greater than 0 (i.e., at least one span is being refused), the alert fires, indicating back‑pressure on the OpenTelemetry Collector processor.
