Amazon Web Services CloudWatch is a feature-monitoring and management service offered by AWS that helps users better understand the operational health and performance of their AWS cloud resources and applications. Actionable insights are available with CloudWatch for AWS, hybrid, on-premises, and other cloud platforms and infrastructure resources. Among the many benefits of using CloudWatch are the ability to track metrics and monitor log files. By obtaining the metrics, users can obtain crucial information about their AWS environment, such as network activities, resource utilization, and application performance. By monitoring the log files, users can gather insight into system behavior and assist in troubleshooting errors.

Metrics

Metrics are the time-ordered sets of data points that are systematically published to Cloud Watch. Think of metrics as the dynamic indicators that record the values of these variables over time. In the context of Amazon Cloud Watch, a metric is a time-ordered collection of data points that are equal to a variable that monitors particular aspects of AWS resources. AWS offers users a wide range of default metrics that are customized for various AWS cloud services. These predefined metrics provide users with instantaneous insights into the operational dynamics of AWS resources. Furthermore, users can expand their monitoring capabilities to create custom metrics through CloudWatch, making it possible for users to monitor and analyze particular performance indicators that correspond to their particular requirements.
