SigNoz can be served under a base path, so you can place it behind a reverse proxy alongside other services on the same domain - for example, https://example.com/signoz/.
A single environment variable is the only configuration required. Everything under SigNoz derives the base path from its value at startup. No image rebuild is needed.
This feature is available from SigNoz v0.121.0 or later.
Configuration
Configure the base path by setting SIGNOZ_GLOBAL_EXTERNAL__URL to your external URL:
SIGNOZ_GLOBAL_EXTERNAL__URL=https://example.com/signoz
SigNoz reads the path component from the URL (e.g. /signoz) and uses it as the base path for all API routes and frontend assets.
Health endpoints (/api/v1/health, /api/v2/healthz, /api/v2/readyz, /api/v2/livez) remain accessible without the base path for container health checks.
Validate
After restarting SigNoz with the updated configuration:
- Open
https://example.com/signoz/in your browser. - Confirm the SigNoz UI loads and in-app navigation works end to end.
- Verify health probes succeed - run the following and confirm it returns
200 OK:
curl -i https://example.com/api/v1/health
Troubleshooting
UI loads but API calls return 404
The base path in SIGNOZ_GLOBAL_EXTERNAL__URL must exactly match what your reverse proxy forwards. Check that the proxy is not stripping the base path before passing requests to SigNoz.
Static assets (JS/CSS) return 404
Ensure the reverse proxy forwards the full path, including the base path, to SigNoz. Stripping the base path on the proxy side breaks asset resolution because SigNoz injects the base path into all asset URLs at startup.
Health probes failing after adding the base path
Health endpoints do not use the base path. Update your container probe to target /api/v1/health directly, without the base path.
Storage or session conflicts when running multiple instances on the same host
Storage keys are scoped to the base path automatically. If you are seeing conflicts, confirm each instance has a distinct base path set via SIGNOZ_GLOBAL_EXTERNAL__URL.
