What metrics for Laravel application monitoring?

As product owner I need metrics to move my business forward, and my product itself is a tool that provide instant and actionable metrics to its users, so I study and practice every day to find the best possible way to make data-driven decisions and avoid unnecessary risks.

I’m not interested in charts that looks good (even if they are), my priority are useful, indeed needful metrics to distinguish between something that doesn’t need to be rushed and something that needs immediate attention to keep your application (and probably your business) stable and secure.
