Functions

func CounterAdd

func CounterAdd[T int64](counter DeferrableCounter[T], delta T, options ...metric.AddOption)

func HistogramRecord

func HistogramRecord[T int64](histogram DeferrableHistogram[T], delta T, options ...metric.RecordOption)

func SetupOTelSDK

func SetupOTelSDK(ctx context.Context, opts ...Option) (shutdown func(context.Context) error, err error)

SetupOTelSDK bootstraps the OpenTelemetry pipeline. If it does not return an error, make sure to call shutdown for proper cleanup.

Types

type DeferrableCounter

type DeferrableCounter[T int64] interface {
	// contains filtered or unexported methods
}

func NewDeferrableInt64Counter

func NewDeferrableInt64Counter(meter metric.Meter, name string, counterOptions []metric.Int64CounterOption, addOptions []metric.AddOption) (DeferrableCounter[int64], error)

type DeferrableHistogram

type DeferrableHistogram[T int64] interface {
	// contains filtered or unexported methods
}

func NewDeferrableHistogram

func NewDeferrableHistogram(meter metric.Meter, name string, histogramOptions []metric.Int64HistogramOption, recordOptions []metric.RecordOption) (DeferrableHistogram[int64], error)

type DeferrableInt64Counter

type DeferrableInt64Counter struct {
	// contains filtered or unexported fields
}

type DeferrableInt64Histogram

type DeferrableInt64Histogram struct {
	// contains filtered or unexported fields
}

type Option

type Option func(*setupConfig)

Option configures SetupOTelSDK behavior.

func WithHTTPClient

func WithHTTPClient(client *http.Client) Option

WithHTTPClient sets a custom HTTP client for all OTLP exporters. Takes precedence over WithHeaderProvider.

func WithHeaderProvider

func WithHeaderProvider(provider func() map[string]string) Option

WithHeaderProvider sets a function that returns headers to inject into every outbound OTLP HTTP request.

func WithResource

func WithResource(r *resource.Resource) Option

WithResource sets an explicit OTel resource to merge with SDK defaults. Caller-provided attributes take precedence on conflict.
