Functions

func Enabled

func Enabled() bool

Enabled returns if metrics are enabled.

func EscapeLabelCharacters

func EscapeLabelCharacters(l string) string

EscapeLabelCharacters replaces invalid prometheus label name characters with "_".

func GetDefaultPushLabels

func GetDefaultPushLabels(ti *env.ScenarioInstanceInfo) map[string]string

GetDefaultPushLabels generates standard Prometheus push labels based on test current test instance info.

func New

New constructs a new metrics service.

Types

type ResourceCollector

type ResourceCollector interface {
	// Name returns the resource collector name.
	Name() string

	// Update updates corresponding resource metrics.
	Update() error
}

ResourceCollector is interface for monitoring resources (cpu, mem, disk, net).

func NewCPUCollector

func NewCPUCollector() ResourceCollector

NewCPUCollector constructs a new CPU usage collector.

This service will regularly read CPU spent time info from process Stat file.

func NewDiskService

func NewDiskService() ResourceCollector

NewDiskService constructs a new disk usage and I/O service.

This service will regularly compute the size of datadir folder and read I/O info of the process.

func NewMemService

func NewMemService() ResourceCollector

NewMemService constructs a new memory usage service.

This service will regularly read memory info from process Status file.

func NewNetService

func NewNetService() ResourceCollector

NewNetService constructs a new network statistics service.

This service will regularly read info from /proc/net/dev file.
