They can be thought of as categories or groups of metrics associated with a particular application, service or resource. They must be unique, and will be created before any metrics can be collected.<\/li><li><strong>Metrics:<\/strong> this is performance data sent to CloudWatch. They can include information about the performance of various AWS resources (<a href=\"https:\/\/datascientest.com\/en\/aws-ec2-how-to-use-amazons-tool\">EC2 instances,<\/a> DynamoDB databases, Lambda functions, etc.). They are identified by a name, a unit of measurement, a dimension and a namespace.<\/li><li><strong>Dimensions:<\/strong> dimensions are additional metric attributes that can be used to filter and segment their data. They are key-value pairs that can be used to create custom views based on different attributes of your AWS environment.<\/li><li><strong>Statistics:<\/strong> these are calculated values for a given metric over a specified period of time. CloudWatch automatically calculates statistics for all metrics and makes them available for analysis and monitoring.<\/li><li><strong>Percentiles (percentages):<\/strong> these measure the distribution of values for a metric, in the form of a percentage. They can be used to understand performance trends and abnormal behaviour of AWS resources.<\/li><li><strong>Alarms:<\/strong> these are threshold rules above which an automated action is triggered when a metric exceeds or falls below a specified threshold. This is an essential tool for monitoring the performance of your AWS resources in real time.<\/li><\/ul>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-798946d elementor-widget elementor-widget-text-editor\" data-id=\"798946d\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>Think of <strong>CloudWatch<\/strong> as a metrics warehouse.
