+## From Manual Tuning to Zero-Config: The AutoScaler That Eliminates Cadence Scaling Headaches

+The following Grafana dashboards demonstrate the CPU utilization issue that AutoScaler solves:

+#### CPU Utilization vs CPU Quota

+#### Worker Instance Count Impact

 This approach prevents the common scenario where compute autoscalers scale down workers that appear idle but are actually critical for maintaining workflow performance. AutoScaler provides a more accurate representation of worker utilization that can be used to make better scaling decisions at both the worker configuration level and the compute infrastructure level.
