Functions

func Otel

func Otel(ctx context.Context, o OtelConfig) (context.Context, func(context.Context), error)

Otel is the primary entrypoint to initialize the o11y system for otel.

func Setup

func Setup(ctx context.Context, o Config) (context.Context, func(context.Context), error)

Setup is the primary entrypoint to initialize the o11y system.

Types

type Config

	// Sender allows setting a custom honeycomb sender, Typically the build-in one is preferred.
	Sender transmission.Sender
	// Metrics allows setting a custom metrics client. Typically setting Statsd/StatsNamespace is preferred
	Metrics o11y.ClosableMetricsProvider
}

func (*Config) OtelSampleRates

func (c *Config) OtelSampleRates() map[string]uint

OtelSampleRates adapts the root o11y package configured map[string]int sample rates to the Otel-required map[string]uint

type OtelConfig

type OtelConfig struct {
	GrpcHostAndPort string
	Dataset         string

	DisableText bool

	SampleTraces  bool
	SampleKeyFunc func(map[string]interface{}) string
	SampleRates   map[string]uint

	Statsd                  string
	StatsNamespace          string
	StatsdTelemetryDisabled bool

	RollbarToken      secret.String
	RollbarEnv        string
	RollbarServerRoot string
	RollbarDisabled   bool

	Version string
	Service string
	Mode    string
}

OtelConfig contains all the things we need to configure for otel based instrumentation.
