Overview

The Multi exporter multiplexes captured spans to a set of delegate exporters. It is useful if you need to export to more than one destination. You may also use it as a "null" exporter by providing no delegates.

Multi delegates to an array of the exporter objects. You can manage the list of exporters using any method of Array. For example:

multi = OpenCensus::Trace::Exporters::Multi.new
multi.export(spans)  # Does nothing
multi << OpenCensus::Trace::Exporters::Logger.new
multi.export(spans)  # Exports to the logger
