USE Method

A resource-centric performance analysis method checking Utilization, Saturation, and Errors for every resource.

Definition

Developed by Brendan Gregg, USE checks each hardware or software resource (CPU, memory, disk, network) for how busy it is, how much work is queued, and error counts. It quickly finds resource bottlenecks.

Example

A disk at 60% utilization but with a long I/O queue shows saturation despite moderate utilization.

Exam tip

Remember USE for infrastructure resources, RED for request-driven services.
