Functions

func CounterAdd

func CounterAdd(name string, v float64)

func CounterInc

func CounterInc(name string)

func ElapsedMs

func ElapsedMs(name string) func()

func GaugeAdd

func GaugeAdd(name string, v float64)

func GaugeDec

func GaugeDec(name string)

func GaugeInc

func GaugeInc(name string)

func GaugeSet

func GaugeSet(name string, v float64)

func HistAdd

func HistAdd[T number](name string, v T)

func Init

func Init(ctx context.Context, namespace string, port int)

func NewCounter

func NewCounter(name string)

NewCounter declares a new counter.

func NewGauge

func NewGauge(name string)

NewGauge declares a new gauge.

func NewHistogram

func NewHistogram(
	name string,
	buckets ...float64,
)

NewHistogram declares a new histogram. Buckets defines the buckets into which observations are counted. Each element in the slice is the upper inclusive bound of a bucket. The values must be sorted in strictly increasing order. There is no need to add a highest bucket with +Inf bound, it will be added implicitly. If Buckets is left as nil or set to a slice of length zero, it is replaced by default buckets. The default buckets are DefBuckets if no buckets for a native histogram (see below) are used, otherwise the default is no buckets. (In other words, if you want to use both reguler buckets and buckets for a native histogram, you have to define the regular buckets here explicitly.)

func RegisterDiskMetrics

func RegisterDiskMetrics(ctx context.Context) error

func RegisterIfaceMetrics

func RegisterIfaceMetrics(ctx context.Context) error
