Viewing Logs

You can view your app logs in Plotly Cloud by going to your app Settings . In the Revisions & logs tab, build logs and runtime logs are displayed for your latest app revision.

Build logs represent statements emitted by Plotly Cloud when it builds your app. You'll see lines for Plotly Cloud using your selected Python version, installing your app dependencies, and more. Build logs can help you troubleshoot an app in the Build Failed status.

Runtime logs represent statements emitted by Plotly Cloud when it starts and stops running your app, as well as anything that your app prints while it's running. Runtime logs can help you troubleshoot an app in the Failing status.

Info

All apps that are successfully published and running on Plotly Cloud have a line Starting gunicorn in their runtime logs. Gunicorn is the WSGI HTTP server that Plotly Cloud uses internally.

To view historical build and runtime logs, select an older revision from the History.

Logs are ordered top-to-bottom (most recent logs last).

Logs are available in Plotly Cloud for approximately 7 days after your app last emitted logs. We recommend downloading them if you need to reference them for a longer period of time.
