DORA_JAEGER_TRACINGinstructions with an OTLP-based tracing flow. - Add a step-by-step SigNoz Docker Compose setup and viewing instructions.
- Update the documented environment variable to
DORA_OTLP_ENDPOINTand add deprecation notes.
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.
| # Tracing | ||
|
|
||
| You can easily integrate jaeger tracing by providing `DORA_JAEGER_TRACING` environment variable | ||
| Dora supports distributed tracing via OpenTelemetry (OTLP). The previous Jaeger integration (DORA_JAEGER_TRACING) has been removed as of recent versions. Use the OTLP endpoint instead. |
|
|
||
| ## Setup with SigNoz | ||
|
|
||
| [SigNoz](https://signoz.io) is the recommended open-source observability backend for dora tracing. |
| ```bash | ||
| docker run -d -p6831:6831/udp -p6832:6832/udp -p16686:16686 jaegertracing/all-in-one:latest | ||
| export DORA_OTLP_ENDPOINT=http://localhost:4317 | ||
| dora run dataflow.yaml --uv |
|
|
||
| - DORA_JAEGER_TRACING is no longer supported and has been removed from the codebase. | ||
| - The OTLP collector in SigNoz listens on port 4317 by default. | ||
| - Metrics ingestion is active when the endpoint is correctly configured. |

Fixes #1313 (reported in dora-rs/dora)
The previous tracing guide referenced DORA_JAEGER_TRACING which has been fully removed from the dora codebase (see dora-rs/dora#1397). This PR updates the documentation to reflect the current recommended setup using SigNoz and OTLP.
Changes:
Tested on: Ubuntu 24.04 (WSL2), dora-cli 0.4.1, SigNoz v0.115.0
