Amazon CloudWatch monitors your Amazon Web Services (AWS) resources and the applications you run on AWS in real-time.You can use CloudWatch to collect and track metrics, which are the variables you want to measure for your resources and applications. CloudWatch alarms send notifications or automatically make changes to the resources you are monitoring based on rules that you define.
Amazon CloudWatch Architecture
Metrics
A metric is the fundamental concept in CloudWatch and represents a time-ordered set of data points. These data points can be either your custom metrics or metrics from other services in AWS. You or AWS products publish metric data points into CloudWatch and you retrieve statistics about those data points as an ordered set of time-series data. You can use metrics to calculate statistics and present the data graphically in the CloudWatch console. Metrics exist only in the region in which they are created.
Namespaces
CloudWatch namespaces are containers for metrics. Metrics in different namespaces are isolated from each other, so that metrics from different applications are not mistakenly aggregated into the same statistics.
Dimensions
A dimension is a name/value pair that helps you to uniquely identify a metric. Every metric has specific characteristics that describe it, and you can think of dimensions as categories for those characteristics. Dimensions help you design a structure for your statistics plan. Because dimensions are part of the unique identifier for a metric, whenever you add a unique name/value pair to one of your metrics, you are creating a new metric.
