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 caluculated 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 generate metrics values

type UptimeGenerator

type UptimeGenerator struct {
}

UptimeGenerator collect uptime

`uptime`: uptime[day] retrieved from /proc/uptime

graph: `uptime`

func (*UptimeGenerator) Generate

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

Generate generate metrics values
