Is there a documentation where I can see consolidated list of all metrics of all services that can be fetched from cloudwatch?

Question

Something like what's there for Azure - https://learn.microsoft.com/en-us/azure/azure-monitor/essentials/metrics-supported
I have searched & closest documents I got were again having links to bunch of other pages! This at best are making referring to these simple details more convoluted & obviously time consuming... Also, referring them offline is a challenge!
All I need is list of services, metric names, unit, aggregation methods supported & description of metric in a standard format.

Answer

There is no single page on AWS that contains all the possible metrics from every AWS service. The closest thing is probably [AWS services that publish CloudWatch metrics](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/aws-services-cloudwatch-metrics.html) which contains a list of all the services that integrate with CloudWatch metrics and a list to their documentation. I noticed that some of those links are actually broken too, which is not a good look.

I'm speculating here, but there is probably no such list because of how AWS is organized internally. The CloudWatch team probably hasn't made available a way for all the other service teams to publish their metrics centrally. Conway's Law sums it up nicely:

> "Any organization that designs a system (defined broadly) will produce a design whose structure is a copy of the organization's communication structure."

Until such a page exists, you'll be stuck reviewing each service's metrics in isolation I'm afraid.
