WHAT IS AMAZON CLOUDWATCH?


PDFRSS

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 variables you can measure for your resources and
applications.

The CloudWatch home page automatically displays metrics about every AWS service
you use. You can additionally create custom dashboards to display metrics about
your custom applications, and display custom collections of metrics that you
choose.

You can create alarms that watch metrics and send notifications or automatically
make changes to the resources you are monitoring when a threshold is breached.
For example, you can monitor the CPU usage and disk reads and writes of your
Amazon EC2 instances and then use that data to determine whether you should
launch additional instances to handle increased load. You can also use this data
to stop under-used instances to save money.

With CloudWatch, you gain system-wide visibility into resource utilization,
application performance, and operational health.


ACCESSING CLOUDWATCH


You can access CloudWatch using any of the following methods:

 * Amazon CloudWatch console – https://console.aws.amazon.com/cloudwatch/

 * AWS CLI – For more information, see Getting Set Up with the AWS Command Line
   Interface in the AWS Command Line Interface User Guide.

 * CloudWatch API – For more information, see the Amazon CloudWatch API
   Reference.

 * AWS SDKs – For more information, see Tools for Amazon Web Services.


RELATED AWS SERVICES


The following services are used along with Amazon CloudWatch:

 * Amazon Simple Notification Service (Amazon SNS) coordinates and manages the
   delivery or sending of messages to subscribing endpoints or clients. You use
   Amazon SNS with CloudWatch to send messages when an alarm threshold has been
   reached. For more information, see Setting up Amazon SNS notifications.

 * Amazon EC2 Auto Scaling enables you to automatically launch or terminate
   Amazon EC2 instances based on user-defined policies, health status checks,
   and schedules. You can use a CloudWatch alarm with Amazon EC2 Auto Scaling to
   scale your EC2 instances based on demand. For more information, see Dynamic
   Scaling in the Amazon EC2 Auto Scaling User Guide.

 * AWS CloudTrail enables you to monitor the calls made to the Amazon CloudWatch
   API for your account, including calls made by the AWS Management Console, AWS
   CLI, and other services. When CloudTrail logging is turned on, CloudWatch
   writes log files to the Amazon S3 bucket that you specified when you
   configured CloudTrail. For more information, see Logging Amazon CloudWatch
   API and console operations with AWS CloudTrail.

 * AWS Identity and Access Management (IAM) is a web service that helps you
   securely control access to AWS resources for your users. Use IAM to control
   who can use your AWS resources (authentication) and what resources they can
   use in which ways (authorization). For more information, see Identity and
   access management for Amazon CloudWatch.
