Yes, there are several ways to get logs and visibility when someone manually promotes a build to production on Vercel:

Build Logs

When you promote a deployment to production, you can access the build logs for that specific deployment 1. These logs show:

• The deployment progress
• Version of build tools used
• Any warnings or errors during the build process
• Details about files and dependencies that were installed or compiled

To access these logs, click the Build Logs button from the production deployment tile in your project's overview page 1.

Deployment Activity

Vercel also provides visibility into deployment activities through:

1. Deployment History: You can see all deployments in your project dashboard, including when they were created and promoted
2. Team Activity: If you're on a team plan, you can see who performed specific actions like promotions
3. Git Integration Logs: If connected to Git, you'll see commit information and deployment triggers

Runtime Logs

Once the promoted deployment is live, you can monitor its runtime behavior through the Logs tab 2. These logs include:

• Function invocations
• Console output from your application
• Real-time request monitoring
• Error tracking and debugging information

Additional Monitoring

For more comprehensive logging, you can:

• Set up log drains to export and store build logs externally 1
• Use Vercel's logging integrations for advanced analytics
• Configure webhooks to get notified of deployment events

The build logs are stored indefinitely for each deployment, so you can always go back and review what happened during a specific promotion 1.
