A closer look at CloudWatch metrics

In the previous chapter, we looked at the CloudWatch service and examined a few of the features that it offered. We even touched on the topic of metrics when creating our alarm.

Metrics, when it comes to applications and monitoring, is data. Many times, this is lots of data streaming constantly. This data is used not only from a technical perspective but also from a business perspective to see how the company is performing.

Metrics are fundamental in CloudWatch. When recorded, a metric represents a time-ordered set of data points that are then published to the CloudWatch service.

Metrics endure in a single region. This means that if you have a multi-region environment, then the metrics for the different resources will be gathered and stored in the same region where the resources have been created and have been running at a point in time. Although you cannot delete metrics, they do expire automatically after 15 months.
