Module: Vmstat

This is a focused and fast library to get system information like:

Memory (free, active, …)
Network Interfaces (name, in bytes, out bytes, …)
CPU (user, system, nice, idle)
Load Average
Disk (type, disk path, free bytes, total bytes, …)
Boot Time
Current Task (used bytes and usage time MACOSX or LINUX ONLY)

Methods

cpu ethernet_devices extract_uvm_val loopback_devices memory network_interfaces snapshot

Public Class methods

cpu()

ethernet_devices()

Filters all available ethernet devices. @return [Array<NetworkInterface>] the ethernet devices

extract_uvm_val(uvmexp, name)

loopback_devices()

Filters all available loopback devices. @return [Array<NetworkInterface>] the loopback devices

memory()

network_interfaces()

snapshot(paths = ["/"])

Creates a full snapshot of the systems hardware statistics. @param [Array<String>] paths the paths to the disks to snapshot. @return [Vmstat::Snapshot] a snapshot of all statistics. @example

  Vmstat.snapshot # => #<struct Vmstat::Snapshot ...>
