How does heroku logs --tail output behave differently from traditional log output?

Logging is an essential part of debugging an application or system. Traditional log output allows users to inspect the log data and see what is happening with their application in a very detailed way. However, heroku logs --tail output offers an alternative that can provide more insight into the activity of your application.

The main difference between Heroku logs --tail output and traditional log output is the way the data is presented. With traditional log output, the logs are organized by timestamp and include data about all requests that have been made to the server, including requests for static assets such as CSS or JavaScript files. The logs can also contain detailed information about errors, such as stack traces and other errors encountered by the application.

Heroku logs –tail output on the other hand provides a more real-time view of what's happening in your application. Instead of showing all requests that have been made to your server, it will only display requests that are actively being processed by Heroku at any given moment in time. This means that you can see exactly what part of your code is currently being executed as well as any errors or warnings produced by it. Additionally, Heroku logs –tail also provides information about a variety of processes running on each dyno including web, worker and one-off processes which can help with debugging process problems within Dynos quickly and easily.
