Query Explanation

The rule computes the 99th‑percentile (p99) of Nginx request durations over the past 2 minutes for each host/node by summing the per‑bucket rates of the histogram nginx_http_request_duration_seconds_bucket, then applies histogram_quantile(0.99, …). The alert fires whenever this p99 latency is greater than 3 seconds for any host‑node pair.
