What metrics do you use to evaluate system performance or health?

To evaluate system performance or status, the following metrics are usually used:

• CPU usage — the percentage of CPU utilization, helps understand how loaded the processor is.
• Memory usage (RAM usage) — how much RAM is occupied.
• Response time — the time it takes for the system to respond to a request.
• Throughput — the number of operations processed per unit of time.
• Disk and network load — read/write speeds and network traffic.

In Python, modules like psutil or built-in monitoring tools can be used to collect such metrics.
