Types

type CPUUsageGenerator

type CPUUsageGenerator struct {
	Interval time.Duration
}

CPUUsageGenerator generates CPU metric values

func (*CPUUsageGenerator) Generate

DiskGenerator XXX

func (*DiskGenerator) Generate

func (g *DiskGenerator) Generate() (metrics.Values, error)

Generate XXX

type InterfaceGenerator

type InterfaceGenerator struct {
	Interval time.Duration
}

InterfaceGenerator generates interface metric values

func (*InterfaceGenerator) Generate

func (g *InterfaceGenerator) Generate() (metrics.Values, error)

Generate interface metric values

type MemoryGenerator

type MemoryGenerator struct {
}

MemoryGenerator collect memory usage

`memory.{metric}`: using memory size[KiB] retrieved from /proc/meminfo

metric = "total", "free", "buffers", "cached", "active", "inactive", "swap_cached", "swap_total", "swap_free"

Metrics "used" is calculated here like (total - free - buffers - cached) for ease. This calculation may be going to be done in server side in the future.

graph: stacks `memory.{metric}`

func (*MemoryGenerator) Generate

func (g *MemoryGenerator) Generate() (metrics.Values, error)

Generate memory values
