## Config
You can configure the middleware using functional parameters


| Function | Argument Type | Description | Default |
| :------------------------ | :-------------------------------- | :--------------------------------------------------------------------------------- | :-------------------------------------------------------------------- |
| `WithNext` | `func(*fiber.Ctx) bool` | Define a function to skip this middleware when returned true .| nil |
| `WithTracerProvider` | `oteltrace.TracerProvider` | Specifies a tracer provider to use for creating a tracer. | nil - the global tracer provider is used |
| `WithMeterProvider` | `otelmetric.MeterProvider` | Specifies a meter provider to use for reporting. | nil - the global meter provider is used |
| `WithPort` | `int` | Specifies the value to use when setting the `net.host.port` attribute on metrics/spans. | Defaults to (`80` for `http`, `443` for `https`) |
| `WithPropagators` | `propagation.TextMapPropagator` | Specifies propagators to use for extracting information from the HTTP requests. | If none are specified, global ones will be used |
| `WithServerName` | `string` | Specifies the value to use when setting the `http.server_name` attribute on metrics/spans. | - |
| `WithSpanNameFormatter` | `func(*fiber.Ctx) string` | Takes a function that will be called on every request and the returned string will become the span Name. | Default formatter returns the route pathRaw |
| `WithCustomAttributes` | `func(*fiber.Ctx) []attribute.KeyValue` | Define a function to add custom attributes to the span. | nil |
| `WithCustomMetricAttributes` | `func(*fiber.Ctx) []attribute.KeyValue` | Define a function to add custom attributes to the metrics. | nil |
