    BatchSize:     10000,
    MaxBufferSize: 50000,
    FlushInterval: 1,
    Source:        "my-app",
    MetricPrefix:  "my.awesome.app",
    PointTags:     make(map[string]string),
}

// Make sure the sender is configured and initialized
err := wfconfig.ConfigureSender()
if err != nil {
    panic(err)
}

// Wrap your handler
http.HandleFunc("/", wfconfig.WrapHandlerFunc(handler))
