Detailed Description

One point-in-time measurement of the host.

Note: Rates (cpu_utilization_percent, process_cpu_percent) are computed from the difference between this reading and the previous one taken on the same path (the background thread, or sample_now()); they are std::nullopt when no counter advanced between the two readings (e.g. two calls within the kernel's 10 ms tick).
