Which one of the following do technology metrics measure?

Technology metrics focus on low-level component measurements such as CPU utilization, memory usage, disk throughput, and application response times. They represent the most granular of ITIL's three metric types - technology, process, and service - and feed upward into service metrics to reflect the overall customer experience. Measuring components directly is the defining purpose of technology metrics.

Processes are measured by process metrics, which assess efficiency and effectiveness indicators such as the percentage of incidents resolved within SLA targets.

The end-to-end service is measured by service metrics, which aggregate technology and process data to reflect the customer's actual experience.

Customer satisfaction is captured through surveys and feedback mechanisms, which contribute to business or service metrics, not technology metrics.
