OpenCensus Agent Reporter

This reporter exports spans to the OpenCensus Agent in the standard protobuf format over grpc.

Installation and Configuration

Erlang

Take a dependency on opencensus_service, e.g. with rebar3 by adding it to your applications list in .app.src.

Configure :opencensus' :reporters to use :oc_reporter_service:

{opencensus, [
    {reporters, [{oc_reporter_service, #{}}]}
...]}

Elixir

Take a dependency on opencensus_service by adding to your deps in mix.exs:

{:opencensus, "~> 0.9.0", override: true},
{:opencensus_service, "~> 0.1"}

(You'll need the override because the opencensus_service package expects version 0.7 of opencensus. It seems to work fine with 0.9, however.)

Configure :opencensus' :reporters in config/config.exs to use :oc_reporter_service:

config :opencensus, :reporters, [{:oc_reporter_service, %{}}]

The map (%{}) at the end gives oc_reporter_service its options. Its defaults are:

%{
  channel_name: :channel_service,
  endpoints: [{:http, 'localhost', 55678, []}],
  options: %{},
  sup_flags: %{intensity: 1, period: 5, strategy: :one_for_one}
}

WARNING: the hostname in endpoints is a charlist, not a binary. If you're pulling the endpoint out of an environment variable, pipe the result from System.get_env/1 through String.to_charlist/1.
