In a Kubernetes environment, vigilantly monitoring your system is absolutely crucial. Why? Because Kubernetes manages lots of containers across different machines, and you need to know how they are doing. Monitoring helps you see what's going on in real-time. It is like having a watchful eye over your containers. If something goes wrong, monitoring will tell you so you can fix it quickly and avoid any interruptions.
It is also helpful to make sure that you are using your resources wisely and not wasting them. And it keeps everything safe and follows the rules by spotting any security issues and making sure you are not breaking any regulations. Thus Kubernetes monitoring serves as a protector for your containerized applications within the Kubernetes framework.
