Metric API: Ability to create histograms like prometheus histograms

[sureshballa]

Do we have ability to create histograms like prometheus histograms from metrics API?

[dyladan]

Not yet. Likely this will be just an aggregator on the value recorder but we're waiting for the spec to finalize this.

Just wanted to check if we have any update on this. Or a sample code of how we can leverage value recorder to implement histograms.

@sureshballa this PR provides that histogram aggregation #1628 , I have tried with the prometheus exporter and have no issue so far:

const valueRecorder = meter.createValueRecorder("request_processing_seconds", {
  description: "Time spent processing request",
  boundaries: [0, 1, 10 , 50 ,95 , 99, 100, Infinity],
});

Thanks, @locmai , is this released for consumption?

I think this can be closed.

Histogram type instrument has been implemented in the latest metrics SDK.
