Determining memory and processor usage in docker caching

Question

How can you determine the memory usage metric provided by Google Cadvisor in docker? Is dynamic stack size, heap requirement, cache skips, code size, swap memory or RAM? as well as for cumulative processor use, in what units of measurement is it calculated? How can you determine this? Are there any documents about this?

NB: I remember that data on the use of container resources for container caching is passed to infuxDB. Among the indicators that he exports are: memory_usage, cpu_cumulative_usage, among others ...

thanks
