class Vmstat::Snapshot
Snapshots help to gather information about the whole system quickly. @attr [Time] at the timestamp, when the snapshot was created. @attr [Time] #boot_time the timestamp, when the system booted. @attr [Array<Vmstat::Cpu>] cpus the data of each and every cpu. @attr [Array<Vmstat::Disk>] disks the disks that are part of the snapshot. @attr [Vmstat::LoadAverage] #load_average current load average at the time
when the snapshot toke place.
@attr [Vmstat::Memory] memory the memory data snapshot. @attr [Array<Vmstat::NetworkInterface>] #network_interfaces the network
interface data snapshots per network interface.
@attr [Vmstat::Task] task optionally the information for the current task @example Creating a snapshot
snapshop = Vmstat::Snapshop.new(["/dev/disk0", "/dev/disk1"])
