If you are a Symfony PHP developer, you will need Symfony monitoring. With the ever-increasing need for web applications to perform at their best, developers require full visibility and observability. This way, they have full control of the performance and its maintenance. Imagine you have created an application. You have deployed it but do not know how it works.
