Constants

const (
	// NormalNaN is a quiet NaN. This is also math.NaN().
	NormalNaN uint64 = 0x7ff8000000000001

	// StaleNaN is a signaling NaN, due to the MSB of the mantissa being 0.
	// This value is chosen with many leading 0s, so we have scope to store more
	// complicated values in the future. It is 2 rather than 1 to make
	// it easier to distinguish from the NormalNaN by a human when debugging.
	StaleNaN uint64 = 0x7ff0000000000002

Functions

func IsStaleNaN

func IsStaleNaN(v float64) bool

IsStaleNaN returns true when the provided NaN value is a stale marker.

Types

type ServiceStaticPrometheus

type ServiceStaticPrometheus struct {
	Yaml           string
	ConfigFilePath string
	// contains filtered or unexported fields
}

func (*ServiceStaticPrometheus) Collect

func (p *ServiceStaticPrometheus) Collect(ilogtail.Collector) error

Gather takes in an accumulator and adds the metrics that the Input gathers. This is called every "interval"

func (*ServiceStaticPrometheus) Description

func (p *ServiceStaticPrometheus) Description() string

func (*ServiceStaticPrometheus) Init

func (p *ServiceStaticPrometheus) Init(context ilogtail.Context) (int, error)

func (*ServiceStaticPrometheus) Start

func (p *ServiceStaticPrometheus) Start(c ilogtail.Collector) error

Start starts the ServiceInput's service, whatever that may be

func (*ServiceStaticPrometheus) Stop

func (p *ServiceStaticPrometheus) Stop() error

Stop stops the services and closes any necessary channels and connections
