Query Explanation

The query computes the per‑second rate of the pilot_duplicate_envoy_clusters counter over the last 5 minutes, sums it across all instances, and fires the alert whenever that sum is greater than zero – i.e., any occurrence of a duplicate Envoy cluster reported by Istio Pilot triggers the alert.
