Overview

Class representing memory in a system. As Host::Processor, this class is also operating system dependent, which means that different information is provided depending on your OS.

The minimum information provided for the supported operating systems is:

  • total memory

  • free memory

Other information can be retrieved via the Host::Processor.get method which returns the information associated with the given key (depending on your OS).

Example usage:

Host::Memory.total    #=> 4023256
Host::Memory.free     #=> 2115874
# For specific information (as in +/proc/meminfo+ for instance), 
# you can use the +get+ method
Host::Memory.get('KernelStack') #=> "1080 kB"
