Query Explanation

The rule calculates each container’s CPU usage percentage (using rate(container_cpu_usage_seconds_total)), compares the current 1‑minute rate to the rate from one minute earlier (or to a 5‑minute rate offset by one minute), takes the absolute difference, and fires when that change is greater than 25 %.
