Graph a Metric
You can select a metric and create a graph of the data in CloudWatch. For example, you can select the CPUUtilization metric for an Amazon EC2 instance and display a graph of CPU usage over time for that instance.
To graph a metric
Open the CloudWatch console at https://console.aws.amazon.com/cloudwatch/.
If necessary, change the region. From the navigation bar, select the region that meets your needs. For more information, see Regions and Endpoints in the Amazon Web Services General Reference.
In the navigation pane, click Metrics.
In the CloudWatch Metrics by Category pane, use the Search Metrics field and categories to find a metric using the metric name, AWS resource, or other metadata.
Use the scroll bar and next and previous arrows above the metrics list to page through the full list of metrics
Select the metric to view, for example, CPUUtilization. A graph appears in the details pane.
To save this graph and access it later, in the details pane, under Actions, click Copy URL, and then in the Copy Graph URL dialog box, select the URL and paste it into your browser.
