SigNoz

Langtrace and SigNoz Integration Guide.

Overview

SigNoz is an open-source observability platform that helps developers monitor their applications and troubleshoot issues. It provides a rich set of features for monitoring and analyzing traces, metrics, and logs.

Environment Variables

Set up the following environment variables to enable OpenTelemetry tracing and send traces to SigNoz:

OTEL_EXPORTER_OTLP_ENDPOINT="https://ingest.us.signoz.cloud:443"
OTEL_EXPORTER_OTLP_HEADERS="signoz-access-token=<token>"
OTEL_RESOURCE_ATTRIBUTES=service.name="rag chatbot"
OTEL_EXPORTER_OTLP_PROTOCOL="grpc"

For the OTEL_EXPORTER_OTLP_PROTOCOL, both grpc and http protocols are supported. Choose the one that best fits your infrastructure setup.

Troubleshooting

• No traces visible: Verify your SigNoz endpoint and token are correct
• Missing spans: Ensure Langtrace is properly initialized before any LLM operations
• Connection issues: Check if your OTLP endpoint is accessible from your application

That’s it! ✨ 🧙‍♂️ Enjoy the high cardinality traces on SigNoz.
