Functions

func ListenAndServe

func ListenAndServe(host string, port int)

ListenAndServe starts an HTTP server and exposes prometheus and pprof metrics. It also exposes a health endpoint that can be probed with `nebula health`.

func NewMeterProvider

func NewMeterProvider() (metric.MeterProvider, error)

NewMeterProvider initializes a new opentelemetry meter provider that exports metrics using prometheus. To serve the prometheus endpoint call ListenAndServe down below.

func NewTracerProvider

func NewTracerProvider(ctx context.Context, host string, port int) (trace.TracerProvider, error)

NewTracerProvider initializes a new tracer provider to send traces to the given host and port combination. If any of the two values is the zero value this function will return a no-op tracer provider which effectively disables tracing.
