Constants

const (

	MemPct = "MEM_pct"
	// MemVirt is the total amount of virtual memory used by the current process,
	// includes physically memory used by code, data and libraries, also pages
	// have been swapped out and pages have been mapped but not used yet.

These are the names of the proxy's resource usage stats.

Functions

func Sample

func Sample(uSampler Sampler) map[string]int64

Sample returns the current resource usage data by performing a new measurement.

Types

type PsutilSampler

type PsutilSampler struct {
	Sampler
}

PsutilSampler is an instance that reports the usage of OS resource.

func New

func New() *PsutilSampler

New a PsutilSampler instance with current process's pid.

type Sampler

type Sampler interface {
	Percent(interval time.Duration) (float64, error)
	MemoryPercent() (float32, error)
	MemoryInfo() (*process.MemoryInfoStat, error)
}

Sampler is an interface that can provide the sampled system resource usage.
