Amazon CloudWatch: The Real-Time Monitoring Solution

Amazon CloudWatch: What is it?

You can keep an eye on your Amazon Web Services (AWS) resources and applications in real time with Amazon CloudWatch. You may use CloudWatch to gather and monitor metrics, which are attributes of your apps and resources that you can quantify.

The CloudWatch home page automatically displays metrics for each AWS service you use. You may also create your own dashboards to display custom sets of metrics of your choosing in addition to analytics about your own apps.

You can configure alerts that automatically adjust the resources you are monitoring or that track metrics and deliver messages when a threshold is reached. To decide whether to start extra instances to handle the growing load, you may, for example, monitor the CPU utilization and disk reads and writes of your Amazon EC2 instances. You can also use this information to stop instances that aren't being used, which can save money.

You can gain system-wide insight into resource utilization, application performance, and operational health with CloudWatch.

The operation of Amazon CloudWatch

Amazon CloudWatch is essentially a measurement repository. An AWS service, such as Amazon EC2, enters metrics into the repository, and statistics are obtained using those metrics. If you upload your own custom metrics to the repository, you can also get statistics on them.

Statistics can be calculated using metrics, and the data can then be graphically shown via the CloudWatch interface.

You can configure alert actions to stop, start, or terminate an Amazon EC2 instance when certain criteria are met. You can also configure alerts to initiate Amazon EC2 Auto Scaling and Amazon Simple Notification Service (Amazon SNS) on your behalf. For more information on configuring CloudWatch alarms, see Alarms.

AWS Cloud computing resources are housed in easily accessible data center buildings. For further scalability and reliability, each data center facility is located in a certain geographic area, known as a Region. Each section is intended to be completely isolated from the others in order to provide the highest level of stability and failure isolation. CloudWatch's cross-Region capability allows you to aggregate data from multiple Regions, even if metrics are stored separately in each Region.

Why Make Use of CloudWatch?

Amazon CloudWatch is a service that monitors apps, responds to performance changes, optimizes resource usage, and provides information on the status of operations. By collecting information from several AWS services, CloudWatch gives customers a uniform view of operational health, lets them set alarms, and reacts to changes automatically.
