CloudWatch operates below the hypervisor. This video illustrates the ability to add custom metrics.
- [Instructor] CloudWatch has the ability to collect metrics…from a number of AWS services.…However, to get a comprehensive understanding…of the operational state of your system,…the stock CloudWatch metrics may not be enough.…Let's explore how you can extend CloudWatch…to track any metric you want, so you can get the insight…that you need.…Let's first walk through exactly why CloudWatch…doesn't natively report on memory usage.…Let's visualize what I like to think of…as the virtualization layer cake.…At the bottom layer of the cake is the physical servers…that AWS designs, builds, and operates.…
On top of that physical layer, AWS installs a hypervisor.…On top of the hypervisor, individual EC2 virtual machines,…or instances, get installed.…It is the job of the hypervisor to map processor, memory,…disk, and network requests from EC2…to the actual hardware on which the instance is running.…CloudWatch has access to metrics…which are visible to the hypervisor.…However, CloudWatch doesn't have visibility…into what is happening inside the operating system…
