By default, we use Jaeger for request tracing within oCIS. You can follow these steps to get started:

  1. Start Jaeger by using the all-in-one docker image:
    docker run -d --name jaeger \
      -p 5775:5775/udp \
      -p 6831:6831/udp \
      -p 6832:6832/udp \
      -p 5778:5778 \
      -p 16686:16686 \
      -p 14268:14268 \
      -p 14250:14250 \
      -p 9411:9411 \
  2. Every single oCIS service has its own environment variables for enabling and configuring tracing.
    1. You can enable and configure tracing on each service individually. For example, enable tracing in Reva when starting the oCIS single binary like this:
      REVA_TRACING_ENDPOINT=localhost:6831 \
      REVA_TRACING_COLLECTOR=http://localhost:14268/api/traces \
      ./bin/ocis server
    2. Enabling and configuring tracing on oCIS itself will forward the configuration to all services:
      OCIS_TRACING_ENDPOINT=localhost:6831 \
      OCIS_TRACING_COLLECTOR=http://localhost:14268/api/traces \
      ./bin/ocis server
      If you want to set individual tracing configuration for each service, make sure to set OCIS_TRACING_ENABLED=false.
  3. Make the actual request that you want to trace.
  4. Open up the Jaeger UI to analyze request traces.
