Resolve Downtime Issues with AWS System Manager Custom Metrics

Consider a situation where you have a downtime issue arising in your machine. Still, the CPU utilization is average, and you cannot think why it is happening. Then custom metrics will come into the picture; you can set some custom metrics like memory utilization metrics to check the downtime is due to high memory utilization or something else.

The first question that strikes in mind is why we need custom metrics when AWS CloudWatch offers a large variety of matrices for your EC2 instances. Sometimes, you need some custom metrics to visualize your instances to know the exact reason for the downtime.
