Open the CloudWatch console at
https://console.aws.amazon.com/cloudwatch/
The CloudWatch overview home page appears.

The overview displays the following items, refreshed automatically.
-
Alarms by AWS service displays a list of AWS services you use in your account, along with the state of alarms in those services. Next to that, two or four alarms in your account are displayed. The number depends on how many AWS services you use. The alarms shown are those in the ALARM state or those that most recently changed state.
These upper areas help you quickly assess the health of your AWS services, by seeing the alarm states in every service and the alarms that most recently changed state. This helps you monitor and quickly diagnose issues.
-
Below these areas is the default dashboard, if one exists. The default dashboard is a custom dashboard that you have created and named CloudWatch-Default. This is a convenient way for you to add metrics about your own custom services or applications to the overview page, or to bring forward additional key metrics from AWS services that you most want to monitor.
Note
The automatic dashboards on the CloudWatch home page display only information from the current account, even if the account is a monitoring account set up for CloudWatch cross-account observability. For information about creating custom cross-account dashboards, see Creating a CloudWatch cross-account cross-Region dashboard with the AWS Management Console.
From this overview, you can see a cross-service dashboard of metrics from multiple AWS service, or focus your view to a specific resource group or a specific AWS service. This enables you to narrow your view to a subset of resources in which you are interested.
