When using Live Optics to assist with sizing a partial infrastructure refresh, it's crucial to capture data that accurately reflects the peak usage periods to ensure the sizing will accommodate the highest demands placed on the infrastructure. Here are the detailed steps and reasons:

Peak Utilization:

Capturing data during peak utilization provides a realistic picture of the maximum load the infrastructure needs to handle.

It ensures that the proposed sizing can accommodate the highest performance and capacity demands, reducing the risk of undersizing.

24-hour Window:

A 24-hour window captures a full day’s cycle, including peak and off-peak hours, providing a comprehensive view of the utilization patterns.

This duration helps in understanding not only the peak loads but also the variations and average loads throughout the day.

Combining these two factors, the most accurate and comprehensive data for sizing would be gathered during 24-hour windows at periods of peak utilization.
