You can see all aspects of your apps with no data loss. We use it exclusively to monitor Kubernetes and Lambda containers. The ability to have an accurate cost for our projects. The ability to be able to see when a server is down so we can plan for it. The ability to track where our servers are and when they are down.

The ability to get alerts when the server is down, the ability to send us alerts when the server is down.
