 The library can be configured through environment variables (with `AUTOSCALER_` prefix) or programmatically. Key settings include:
 
-- `AUTOSCALER_TARGET_VALUE`: Target metric value per pod
+- `AUTOSCALER_TARGET_VALUE`: Target metric value per pod (mutually exclusive with `TOTAL_TARGET_VALUE`)
+- `AUTOSCALER_TOTAL_TARGET_VALUE`: Total target metric value across all pods (mutually exclusive with `TARGET_VALUE`)
 - `AUTOSCALER_STABLE_WINDOW`: Time window for metric averaging (default: 60s)
 - `AUTOSCALER_PANIC_THRESHOLD_PERCENTAGE`: When to enter panic mode (default: 200%)
