There is no doubt that looking at response times and memory usage is essential to understanding the general health and performance of your application. But as I am sure you are aware, there is more than one way to monitor an application. Approaching monitoring from a different angle can be a powerful way of gaining new insights.

There is no denying the popularity of PHP. It has been a constant force in the web development world since its release way back in 1995. And now in 2019, thanks to Laravel, it is still going as strong as ever! Here at Scout, recently we have been working hard on providing a PHP performance monitoring agent to sit alongside our existing ruby, python and elixir agents.
