        FailureRatio = 0.5,
        MinimumThroughput = 8,
        SamplingDuration = TimeSpan.FromSeconds(10),
        BreakDuration = TimeSpan.FromSeconds(5),
        OnOpened = d => Console.WriteLine($"[{breaker.ResourceName}] opened for {d.TotalSeconds}s"),
        OnClosed = () => Console.WriteLine($"[{breaker.ResourceName}] closed"),
