I realized when opening open-telemetry/opentelemetry-swift#355 that the current prometheus spec for histograms is incorrect (though almost all implementations of prometheus exporters is correct).

From the prometheus spec:

Each bucket count of a histogram named x is given as a separate sample line with the name x_bucket and a label {le="y"} (where y is the upper bound of the bucket).

From the OpenMetrics spec:

The MetricPoint's Bucket Values Sample MetricNames MUST have the suffix "_bucket".

This corrects our specification to be in-line with prometheus and OM specs
