Istio Pilot high total request rate warning
Number of Istio Pilot push errors is too high (> 5%). Envoy sidecars might have outdated configuration.

The query computes the percentage of Istio Pilot XDS push errors by dividing the per‑minute error rate (sum(rate(pilot_xds_push_errors[1m]))) by the total XDS push rate (sum(rate(pilot_xds_pushes[1m]))) and multiplying by 100. The alert triggers when this error percentage exceeds 5 % over the last minute, meaning more than one in twenty configuration pushes are failing and Envoy sidecars may have stale configs.
