Read deployment and runtime logs

Step 1 Open Logs

In the sidebar, select Operations and then Logs. The page lists the sites that have logs. Click Deployments for a site's deployment history or Runtime logs for what it is doing now.

You can also open a site and select the Deployments or Monitoring tab.

Step 2 Find the deployment

The Deployment history lists every deploy with its commit, branch and date. Use Search commits…, the branch filter or the date filter to find the one you need.

Open the actions menu of a deployment and choose View build logs.

Step 3 Read the build log

If the build printed errors or warnings, a Problems section sits above the log with their count. Click a problem to jump to its line in the log.

The Build logs section holds the full output. You can search in it, download it or copy it, for example to share it with a teammate. Use the copy button in Problems to copy only the errors and warnings.

Step 4 Follow the runtime logs

Open the site's Monitoring tab and select Logs. The lines refresh every 5 seconds while the button says Live. Click it to pause.

• Type in Search runtime logs… to find a message.
• Filter by level: All levels, error, warn, info or debug.
• Show the Last 100 lines, Last 250 lines or Last 500 lines.

For a Node app, the logs are its own output, and a badge shows whether the process is online. For PHP and static sites, each line starts with its source, such as the web server's error log, the PHP error log, the Laravel log or the log of a queue worker or cron job.
