def buffers(refresh=false)
  get_meminfo(true) if refresh
  as_integer @info[:Buffers]
end

#free(refresh = false) ⇒ Object

Sugar. Equivalent to Host::Memory.get(‘MemFree’) with implicit transformation to integer (in kB).

def free(refresh=false)
  get_meminfo(true) if refresh
  as_integer @info[:MemFree]
end

#get(key) ⇒ Object

Retrieves specific information for the given key (as some exotic information in /proc/meminfo, for instance).

def get(key)
  @info[key.to_sym]
end

#refresh ⇒ Object

Refreshes your memory information, reading /proc/meminfo once again

end

#total(refresh = false) ⇒ Object

Just sugar. Equivalent to Host::Memory.get(‘MemTotal’) with implicit transformation to integer (in kB) You can pass it a boolean option. If true, information will be reloaded. Defaults to false. Equivalent to:

Host::Memory.refresh.total
