Overview ¶

Package otel provides OpenTelemetry setup for metrics (Prometheus) and optional tracing (OTLP HTTP). When disabled, global OTel providers remain no-ops with zero overhead.

func PrometheusHandler() http.Handler
func Setup(cfg Config, logger *slog.Logger) (shutdown func(context.Context) error, err error)
type Config

Functions ¶

func PrometheusHandler ¶

func PrometheusHandler() http.Handler

PrometheusHandler returns an HTTP handler that serves Prometheus metrics.

func Setup ¶

func Setup(cfg Config, logger *slog.Logger) (shutdown func(context.Context) error, err error)

Setup initialises the global OTel meter and tracer providers. When cfg.Enabled is false it returns a no-op shutdown. The returned function must be called on process exit to flush pending telemetry.

Types ¶

type Config ¶

type Config struct {
	Enabled        bool
	TracesEndpoint string // OTLP HTTP endpoint, e.g. "http://localhost:4318"
	ServiceName    string // defaults to "denkeeper"
}

Config mirrors config.OTelConfig from the TOML layer.
