`module Linux`

Linux host memory: tries cgroup v2, then cgroup v1, then /proc/meminfo.

Nested Classes and Modules

class CgroupV1: Captures host memory limits and usage from a cgroup v1 filesystem.
class CgroupV2: Captures host memory limits and usage from a cgroup v2 filesystem.
class Meminfo: Captures host memory from Linux /proc/meminfo.

Definitions

`def self.capture(cgroup_root: DEFAULT_CGROUP_ROOT)`

Capture host memory from the available Linux interface.

Signature

parameter　cgroup_root　String: The root of the cgroup filesystem.
returns　Host::Memory | Nil: The captured host memory, if available.

Implementation

def self.capture(cgroup_root: DEFAULT_CGROUP_ROOT)
	if Memory::Linux::CgroupV2.supported?(cgroup_root)
		if capture = Memory::Linux::CgroupV2.new(cgroup_root: cgroup_root).capture
			return capture
		end
	end
	
	if Memory::Linux::CgroupV1.supported?(cgroup_root)
		if capture = Memory::Linux::CgroupV1.new(cgroup_root: cgroup_root).capture
			return capture
		end
	end
	
	return Memory::Linux::Meminfo.new.capture if Memory::Linux::Meminfo.supported?
