Eyes on the Metrics

Even when we take our best guess on sizing, not all things will be perfect. This is where the wealth of metrics that AWS provides can really help us narrow in on our baseline workload. Some are baked into the AWS platform itself, and others can be used with third-party tools.

Usage reports

A quick way to get raw usage data is via Usage Reports. You simply select the service you want to know about, the date range, and the format—either XML or CSV. Because this is raw data, interpreting the data is not very intuitive, and it takes some exploring to figure out which metrics to use. Additionally, if the dataset is very large, the tool just truncates and recommends using a smaller duration. Nonetheless, it may prove valuable.
