Tracing

This document provides a guide on how to set up tracing for Dragonfly, which is essential for monitoring and debugging distributed systems.

Setup Jaeger​

Set up a Jaeger instance to collect and visualize tracing data from Dragonfly components, refer to the Jaeger documentation for detailed instructions.

docker run --rm --name jaeger \
  -p 16686:16686 \
  -p 4317:4317 \
  -p 4318:4318 \
  -p 5778:5778 \
  -p 9411:9411 \
  jaegertracing/jaeger:2.3.0

Configure the tracing endpoint in Dragonfly​

Add tracing configuration as follows(in Manager, Scheduler and Dfdaemon)​

tracing:
  # Jaeger endpoint url, like: jaeger.dragonfly.svc:4317.
  addr: jaeger.dragonfly.svc:4317

Access the Jaeger UI​

Jaeger will automatically collect the tracing data from Dragonfly components. You can access the Jaeger UI at http://localhost:16686 to visualize the traces.
