Logs

Each block has its own real-time logs, accessible directly from the Logs tab of its configuration panel. No external logging service to configure — everything is built in.

Per-block logs​

Click on a block in the canvas, then open the Logs tab to see the live output.

Real-time logs of an application block

The logs display the standard output of your service — the same logs you would see with docker logs or kubectl logs, but directly in the Fransys interface.

What you see​

  • HTTP logs — Incoming requests with source IP, method, URL, response code, and user agent
  • Error logs — Application errors, missing files, exceptions
  • Application logs — Everything your application writes to stdout/stderr

The Search logs field lets you filter logs in real time to quickly find a specific entry — a URL, an error code, an IP.

Debugging​

Logs are the first debugging tool on Fransys. When a deployment fails or an application doesn't respond:

  1. Open the affected block
  2. Go to the Logs tab
  3. Identify the error in the output
tip

Check the logs immediately after a deployment to verify your application starts correctly. It's the fastest way to identify a configuration problem or a missing dependency.
