Hi, I'm having trouble figuring out if the +Inf bucket is optional.
The client_model protobuf says it's optional: <goog_966920514> https://github.com/prometheus/client_model/blob/63fb9822ca3ba7a4ba5184071fb8f2ea000a99ef/io/prometheus/client/metrics.proto#LL71C89-L71C114 The OpenMetrics protobuf says buckets are optional https://github.com/OpenObservability/OpenMetrics/blob/1386544931307dff279688f332890c31b6c5de36/proto/openmetrics_data_model.proto#L140 The OpenMetrics specification says "Histogram MetricPoints MUST have one bucket with an +Inf threshold.". https://github.com/OpenObservability/OpenMetrics/blob/1386544931307dff279688f332890c31b6c5de36/specification/OpenMetrics.md So, does it depend on the format (required in text format, optional in protobuf)? Bonus question: What about buckets for native histograms, are they optional? Fabian -- You received this message because you are subscribed to the Google Groups "Prometheus Developers" group.
