Query Explanation

The rule computes the 99th‑percentile request latency for Promtail by summing the per‑second rates of all latency buckets over the last 5 minutes and applying histogram_quantile(0.99). If this 99th‑percentile latency exceeds 1 second, the alert triggers, indicating the specified job/route is experiencing high latency.
