 - **Data source:** Prometheus
 - **Query (A):**
   ```promql
-  changes(container_start_time_seconds{name!=""}[10m])
+  sum by (name) (changes(container_start_time_seconds{name!=""}[10m]))
+  +
+  count by (name) (count_over_time(container_start_time_seconds{name!=""}[10m])) - 1
   ```
 - **Expression (B):** Threshold — `A IS ABOVE 3`
 - **Evaluate every:** `1m`
