Normalized Core Scaling Frequency Over Time

Description

Track how individual CPU cores scale their frequencies over time. This heatmap visualization helps reveal dynamic behavior in response to system load, thermal conditions, or power-saving policies. Use it to identify cores stuck at the minimum or maximum frequencies, detect frequency oscillations, and optimize workloads to increase energy efficiency.

Use cases

• Validate scaling policies and real-time frequency changes
• Identify thermal throttling or power-saving behavior
• Detect cores stuck at minimum or maximum frequency
