choval / sys-stats example snippets

$stats = new \Choval\System\Stats;

Creates the stats object

/*
Memory usage of current PHP execution.
All results in Bytes as PHP memory_get_usage & memory_get_peak_usage.
Array
(
  [peak] => inactive+active peak
  [peak_active] => active peak
  [current] => inactive+active currently
  [current_active] => active currently
)

/*
Memory stats.
All results in MiB, not MB.
Array
(
  [total] => system memory
  [free] => free memory (keep in mind linux memory usage, this will usually be close to 1-2)
  [used] => memory under use by applications and system
  [available] => available memory for use
  [capacity] => PERCENTAGE (without '%') of available memory/total memory

/*
Gets the CPU model, repeated by number of (logical) CPUs (ncpu)

Gets the CPU load, all results in PERCENTAGE (without '%').
Unlike PHP's results, these are percentage of the system capacity already.
Keep in mind some systems may underclock depending on load.
Array
(
  [1_min] => PERCENTAGE of load/capacity last min

Disk stats.
All results in MiB, not MB. NOT BYTES!
Only return mounted disks.

This returns the same data for the disk/partition the current working dir is using.
Or point to a different directory and get the stats.

Runs the stats every 60 secs in the background.
All methods will return a React\Promise\Promise as well,

Forces a refresh of all data ignoring the frequency.
Will not reset the frequency timer.
Returns a promise.

Returns the time of the stats.
Does not return a promise!
