Motivation

Sample Phoenix applications to demonstrate the use ExRay and OpenTracing via Otter

Up And Running

  1. Start Jaeger Docker Image

    docker run -d -e COLLECTOR_ZIPKIN_HTTP_PORT=9411 \
-p5775:5775/udp -p6831:6831/udp -p6832:6832/udp \
-p5778:5778 -p16686:16686 -p14268:14268 -p9411:9411 \
jaegertracing/all-in-one:latest

  2. Start TraceMe Phoenix App

    This is the main application that retrieves available castles and their associated avatars

    You will need to run a local instance of Postgres and modify the db config to match your environment.

    cd traceme
mix do deps.get, ecto.create, ecto.migrate
mix run priv/repo/seeds.exs
mix phx.server

  3. Start Avatars Phoenix App

    This app simulate avatar generation.

    cd avatars
mix do deps.get, phx.server

  4. Open Jaeger UI

    Select the TraceMe service and observe the various spans associated with the api calls below.

      open http://localhost:16686

  5. Exercise the tracing APIs

    # Regular call
curl -XGET http://localhost:4000/api/castles
# GenFlow call
curl -XGET http://localhost:4000/api/castles_flow
# External Avatar Service call
curl -XGET http://localhost:4000/api/castles_svc
