UPI Utilization Bound

Metric Description

This metric represents percentage of elapsed time the system spent with high UPI utilization. Explore the Bandwidth Utilization Histogram and make sure the Low/Medium/High utilization thresholds are correct for your system. You can manually adjust them, if required.

Note

The UPI Utilization metric replaced QPI Utilization starting with systems based on Intel® microarchitecture code name Skylake.

Possible Issues

The system spent much time heavily utilizing UPI bandwidth. Improve data accesses using NUMA optimizations on a multi-socket system.
