Is it possible to change the default RequestDuration's options?

Is there a way to customize the default histogram used by the UseHttpMetrics middleware? I’d like to have custom buckets and an extra label for the request route. I couldn’t find any documentation to do this. Let me know if I’ve missed it.

Thanks

That was it, thank you!

Finally fixed the above issue by

app.UseHttpMetrics(opt => {
                opt.RequestDuration.Histogram = Metrics.CreateHistogram("app_specific_name", "app_specific_help",
                new HistogramConfiguration
                {
                    Buckets = Histogram.ExponentialBuckets(0.001, 2, 16),
                    LabelNames = HttpRequestLabelNames.All.concat(new [] {"xxx"}).toArray()
                });

                opt.AddCustomLabel("xxx", _ => "yyy");
            });
