Troubleshooting

TraceLLM UI Shows No Traces

Check:

1. The hosted API is reachable:

https://api.tracellm.in/health

1. SDK environment is set:

TRACELLM_ENDPOINT=https://api.tracellm.in
TRACELLM_API_KEY=trllm_...

1. API key belongs to the account/project shown in the UI.

2. Project config has tracing enabled.

3. Sampling rate is above 0.

API Key Fails

Create a new API key in the UI and copy it immediately. Full secrets are only shown once.

Then rerun:

TRACELLM_API_KEY=trllm_new_key

Provider Example Fails

Check the provider key:

LLM_PROVIDER=openai
OPENAI_API_KEY=sk_...

For Anthropic:

ANTHROPIC_API_KEY=sk-ant-...

For Gemini:

GEMINI_API_KEY=...

External Export Does Not Show In SigNoz

Check the destination in Exports:

• destination is enabled
• endpoint is the OTLP HTTP base URL
• required headers are present
• Send test trace returns ok
• export config allows the span kinds and fields you expect

A failed external export does not block TraceLLM ingestion. Your traces should still appear in the TraceLLM dashboard.
