The `precpu_stats` is the CPU statistic of the *previous* read, and is
used to calculate the CPU usage percentage. It is not an exact copy
of the `cpu_stats` field.
If either `precpu_stats.online_cpus` or `cpu_stats.online_cpus` is
nil then for compatibility with older daemons the length of the
corresponding `cpu_usage.percpu_usage` array should be used.
To calculate the values shown by the `stats` command of the docker cli tool
the following formulas can be used:
* used_memory = `memory_stats.usage - memory_stats.stats.cache`
* available_memory = `memory_stats.limit`
* Memory usage % = `(used_memory / available_memory) * 100.0`
* cpu_delta = `cpu_stats.cpu_usage.total_usage - precpu_stats.cpu_usage.total_usage`
* system_cpu_delta = `cpu_stats.system_cpu_usage - precpu_stats.system_cpu_usage`
* number_cpus = `lenght(cpu_stats.cpu_usage.percpu_usage)` or `cpu_stats.online_cpus`
* CPU usage % = `(cpu_delta / system_cpu_delta) * number_cpus * 100.0`
