Package view contains support for collecting and exposing aggregates over stats.
|
|
|
|
In order to collect measurements, views need to be defined and registered.
|
|
A view allows recorded measurements to be filtered and aggregated over a time window.
|
|
|
|
All recorded measurements can be filtered by a list of tags.
|
|
|
|
OpenCensus provides several aggregation methods: count, distribution and sum.
|
|
Count aggregation only counts the number of measurement points. Distribution
|
|
aggregation provides statistical summary of the aggregated data. Sum distribution
|
|
sums up the measurement points. Aggregations are cumulative.
|
|
|
|
Users can dynamically create and delete views.
|
|
|
|
Libraries can export their own views and claim the view names
|
|
by registering them themselves.
|
|
|
|
Exporting
|
|
|
|
Collected and aggregated data can be exported to a metric collection
|
|
backend by registering its exporter.
|
|
|
|
Multiple exporters can be registered to upload the data to various
|
|
different backends. Users need to unregister the exporters once they
|
|
no longer are needed.
