Important changes

Breaking changes

  • Added description field to LabelKey in metricdata package. This is a breaking change. However, the effect should be minimal as it is only used by stackdriver exporter.
  • Prometheus, zipkin and jaeger exporters are removed from go.opencensus.io and are moved contrib.go.opencensus.io. This is another breaking change ONLY if the version is not locked using either go.sum or Gopkg.lock

Features

  • Added support for Cumulative and Derived Cumulative metrics. It is similar to Gauge and Derived Gauge, with key difference that the value of a Cumulative can only go up.
  • Added constant labels for Gauges and Cumulatives.
  • Added example for Gauge and Derived Gauge.
  • Added Log Exporter to export metrics and trace spans to a log file.
