cpu usage unit is ns，How to correspond to percent？

/api/v1/model/namespaces/{namespace-name}/pods/{pod-name}/metrics/cpu-usage
Returns a set of (Timestamp, Value) pairs for the requested pod-level metric

Every timestamp, How much is the total time?

If a process were to run on one cpu continuously for a second, its usage
will be 1e+9 nanoseconds. If it ran on n cores continuously its usage
will n * 1e+9 nanoseconds. Does this make sense?

Percentage will be usage_in_nanoseconds / (capacity_in_absolute_cores *
1e+9).

Meanwhile we are also working on adding an utilization metric.

Since there was no follow up, I assume @vishh's clarification fixed the issue.

@vishh Can u please still elaborate about the cpu metric shown in :10255/stats/summary
