EC2 Instances page in the AWS EC2 Instances view

An EC2 instance is a virtual machine in the Elastic Compute Cloud (EC2) that is used for running the applications in the AWS environment. The EC2 Instances page in the AWS EC2 Instances view provides an overview of all available EC2 instances. It lets you view capacity and decision support metrics at the instance level in EC2 instance views.

To access this page, in the navigation pane of the Views tab, select Views > Cloud > AWS > AWS EC2 Instances. By default, the EC2 Instances page is displayed. 

EC2 Instances table 

The EC2 Instances table lists the following information for each EC2 instance. By default, some columns are hidden. You can show or hide columns by using the action menuthat is located next to the EC2 instances table title. You can sort columns in tables alphabetically, or by size. For more information, see Managing charts and tables in Views.

ColumnDescriptionStatistical type Metrics 
Instance Name

Name of the AWS instance. Clicking one of the instances in this column of the summary view takes you to the EC2 Instances details view.

Last Value NAME
Availability ZoneName of the availability zone to which this instance belongs to.Last ValueAVAILABILITY_ZONE
Requested Instance Type

Instance type specifies the required resources to run this instance.

File System Days to Saturation

The projected amount of time before the file system runs out of available storage capacity. This metric is displayed only if file system utilization is available for a minimum of five days.

  • It displays a number of days to saturation.
  • If the days to saturation value is 91 days or beyond, this field displays Not saturated.
  • If the memory is already saturated, it displays Saturated.

Detailed information about an EC2 instance

After you click the EC2 instance in the Instance Name column, the details for that instance are displayed in the EC2 Instance Details page. The EC2 Instance Details page displays the following information:  


Section or PanelDescription
General details section

General details, such as EC2 instance name and type are displayed. The type is Virtual Machine - AWS.

Related Information panel

Links in the Related Information panel displays other information related to the selected instance. 

Summary tab

Summary tab, displayed by default, shows details for the selected instance in a horizontal summary table, as well as charts. 

Core metrics for the selected entity are displayed as analysis charts, depending on available data. At the bottom of each chart is a link that takes you to the Data Explorer view for the specific resource type, and displays charts and information for a larger set of metrics.

To return to this page, click the arrow icon on the top-right side in the Data Explorer tab.

Important

The data displayed in Data Explorer view charts for any resource part of this view category, is based on the time filter that is applied to the primary view in this tab. You can select Advanced time periods (other than default/basic) from the Data Explorer view for the selected resource, to view charts over a different time resolution.

Configuration Details tabDisplays the configuration matrix for the selected instance. 
File Systems

Displays information for all file systems of the instance. For more information, see File Systems of the instance.

File Systems of the instance

The File Systems tab in the EC2 Instance Details page displays the following information for all file systems of the selected instance.
