This repository contains the Go implementation of the OpenCensus Agent (OC-Agent) Exporter. OC-Agent is a deamon process running in a VM that can retrieve spans/stats/metrics from OpenCensus Library, export them to other backends and possibly push configurations back to Library. See more details on OC-Agent Readme.
Note: This is an experimental repository and is likely to get backwards-incompatible changes. Ultimately we may want to move the OC-Agent Go Exporter to OpenCensus Go core library.
