Functions

func GetDiskUsage

func GetDiskUsage() map[string]float64

return disk usage as GiB

TODO different functions for all disks / a specified disk? FIXME Wrong Disk values for docker !!! (probably because counting also virtual mountpoints?)

func GetDisks

func GetDisks() []disk.PartitionStat

return all physical disks, USB and CD-ROM devices

An example output: device: /dev/example, mountpoint: /, fstype: ext4, opts:rw,noatime
