- Prevent negative measurements in Histogram Instruments so we
can include monotonic sum in the data and export to prometheus.
- Remove explicit monotonicity argument to aggregators and always infer
from instrument type.
- Expand list of supported instruments for Sum aggregation with details
on default aggregation.
- Add note on handling `sum` in histogram for instruments that allow
negative measurements.

There was a problem hiding this comment.
Looks good to me. If there is demand for a histogram of signed measurements, my preference then would be to add a field to encode the primitive measurement type (which is either Counter, UpDownCounter, or Gauge, in which case the Sum is not necessarily well-defined for Gauge histograms, as I wrote in open-telemetry/oteps#156).
