If I’m thinking of what’s the best health monitor for your apps and servers on AWS, it’s CloudWatch. This is because it helps one to know if their website is running smoothly and also decode when something is slow or broken.
It depends on your setup and goals. For critical systems, check CloudWatch dashboards and alarms daily to catch issues early. For less critical services, reviewing weekly or relying on automated alerts can be enough. You need to regularly audit alarms to ensure they are still relevant.
