Query Explanation

The query calculates the 99th‑percentile latency of unary gRPC server calls for each grpc_service/grpc_method over the past minute using histogram_quantile(0.99, …), and the alert fires when that latency exceeds 0.15 seconds. In other words, any service‑method pair whose 99th‑percentile request handling time is over 150 ms will trigger the alert.
