At pamediakopes.gr we have many applications built with Rails, each one generating a huge amount of logs. These logs are mostly used for monitoring/alerting and of course debugging. However, your application’s logs have the potential to help you get more insights on your applications and how they interact with other systems, without necessarily using sophisticated 3rd party applications. The challenging part is extracting valuable information and doing it fast! In an attempt to try to get more insights of what is happening during a request, we started experimenting with the idea of using specific information from our Rails logs in order to visualize service dependencies, template rendering and more.
