You cannot use summaries with the OpenTelemetry API, and I don't believe there is interest in adding API surface to include summaries. It would need to be added to the specification in order for us to support it in this repository.

We recommend using a Histogram instrument instead, e.g. with Float64Histogram():

opentelemetry-go/metric/meter.go

Line 117 in 1e1cc90

Float64Histogram(name string, options ...Float64HistogramOption) (Float64Histogram, error)

If you really want a summary, it will be possible for bridges, such as the OpenCensus bridge or Prometheus bridge to produce summary data after #4622. This means will eventually be possible to use the prometheus client_golang to create a Summary, and add it to metrics exported by OpenTelemetry using the Prometheus bridge.

Closing as not planned. I'm happy to answer further questions, but I don't think the OTel Go API is going to support summaries.
