Release v0.10.0 Metrics Exporter
Metric Support
This release supports a new api to consume metrics data model and export it to stackdriver backend. The previous api consumed view data model. Both apis are supported and pervious api will continue to work as before.
Additional apis, StartMetricsExporter and StopMetricsExporter are introduced to work with new model of Interval Reader and Reader introduced in version 0.20.0 of OpenCensus Go library. The reader allows to read metrics from all producers registered with the library. StartMetricsExporter starts the interval reader which periodically reads metrics from all producers and exports them to the backend.
Using Metrics Data Model (New)
exporter := stackdriver.NewExporter(stackdriver.Option{})
exporter.StartMetricsExporter()
defer exporter.StopMetricsExporter()Using View Data Model (Old)
exporter := stackdriver.NewExporter(stackdriver.Option{})
view.RegisterExporter(exporter)Note: Use only one approach. Using both approach simultaneously will result into unspecified behavior.

Release v0.9.1 (deduplicated metrics and CreateTimeSeriesRequests)
With these release, we've fixed a years-long standing issue in which uploading duplicate metrics within the same TimeSeries would cause this kind of error
err: rpc error: code = InvalidArgument desc = One or more TimeSeries could not be written:
Field timeSeries[?] had an invalid value: Duplicate TimeSeries encountered.
Only one point can be written per TimeSeries per request.: timeSeries[?]By duplicate metrics, meaning those metrics that share the same "Type"/"Name" e.g. for illustrative purposes
{
"name": "projects/census-demos",
"time_series": [
{
"metric": {
"type": "custom.googleapis.com/opencensus/oce/dev/latency"
},
"points": [<points...>]
},
{
"metric": {
"type": "custom.googleapis.com/opencensus/oce/dev/latency"
},
"points": [<other_points...>]
}
]
}
which had plagued even the view.Exporter aka OpenCensus StatsExporter from day 1.
With the PR #74 to fix issue #73, there is a deduplication process that prevents putting duplicated Metrics in the same CreateTimeSeriesRequest.
The above issue #73 was exacerbated when Stackdriver Metrics exporter was added to the OpenCensus Agent and metrics were streamed in from various sources concurrently.
OpenCensus Proto Metrics exporter
With this release, this Stackdriver exporter now accepts OpenCensus Proto Metrics and converts them into Stackdriver Metrics. This is complementary to the first exporter which received view.Data aka OpenCensus Stats and converted those to Stackdriver Metrics.
The output of exporting OpenCensus Proto Metrics and OpenCensus stats aka view.Data is exactly the same and enforced by tests. This ensures that if a program was running alright before while using view.Data, that with Proto Metrics it will run transparently too.
