Observability

CPU Utilization

CPU utilization measures how much processing capacity is busy during an interval. Interpretation depends on whether the metric is per core, per process, or normalized across all available processors; a single percentage can hide uneven usage.

Also known as: CPU usage

Why it matters

Processor usage helps distinguish compute bottlenecks from serial work and I/O waits.

Practical example

Low aggregate CPU usage during a build may indicate serial work or time waiting for disk and network I/O.
