PRTG Manual: AWS EC2 v2 Sensor
The AWS EC2 v2 sensor monitors the performance of an Amazon Web Services (AWS) Elastic Compute Cloud (EC2) instance by reading its data from Amazon CloudWatch via the AWS API.
If you use the same Identity and Access Management (IAM) policy that you use for this sensor, you must update it. For more information, see the Knowledge Base: How do I set permissions for the Amazon Web Services (AWS) API key to use certain sensors in PRTG?
For a list of metrics that this sensor supports, see section Supported Metrics.
For a list of dimensions that this sensor supports, see section Supported Dimensions.
For a list of regions that this sensor supports, see section List of Supported AWS Regions and Their Codes.
For a detailed list and descriptions of the channels that this sensor can show, see section Channel List.

- This sensor requires permissions for the AWS API key.
- This sensor requires credentials for AWS in settings that are higher in the object hierarchy.
- This sensor supports IPv6.
- This sensor has a low performance impact.
- This sensor uses lookups to determine the status values of one or more channels.
- Amazon can charge you based on the number of API calls that the sensor sends to the Amazon servers. For more information, see Amazon CloudWatch Pricing – Amazon Web Services (AWS).
- It can take up to several minutes before objects appear in the Add Sensor dialog.

Sensor Name |
Enter a name to identify the sensor. By default, PRTG shows this name in the device tree, as well as in alarms, logs, notifications, reports, maps, libraries, and tickets.
|
Parent Tags |
The tags that the sensor inherits from its parent device, parent group, and parent probe.
|
Tags |
Enter one or more tags. Confirm each tag with the Spacebar key, a comma, or the Enter key. You can use tags to group objects and use tag-filtered views later on. Tags are not case-sensitive. Tags are automatically inherited.
The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:
|
Priority |
Select a priority for the sensor. This setting determines the position of the sensor in lists. The highest priority is at the top of a list. Choose from the lowest priority ( |
Setting |
Description |
---|---|
ID |
The ID of the AWS EC2 instance that this sensor monitors. |
Name |
The name of the AWS EC2 instance that this sensor monitors. |
Region |
The region in which the AWS EC2 instance runs.

Primary Channel |
Select a channel from the list to define it as the primary channel. In the device tree, the last value of the primary channel is always displayed below the sensor's name. The available options depend on what channels are available for this sensor.
|
Graph Type |
Define how different channels are shown for this sensor:
|
Stack Unit |
This setting is only visible if you enable Stack channels on top of each other as Graph Type. Select a unit from the list. All channels with this unit are stacked on top of each other. By default, you cannot exclude single channels from stacking if they use the selected unit. However, there is an advanced procedure to do so. |

Result Handling |
Define what PRTG does with the sensor result:
|
By default, all of these settings are inherited from objects that are higher in the hierarchy. We recommend that you change them centrally in the root group settings if necessary. To change a setting for this object only, click under the corresponding setting name to disable the inheritance and to display its options.
For more information, see section Inheritance of Settings.
This sensor has a fixed minimum scanning interval for performance reasons. You cannot use a shorter scanning interval. Consequently, shorter scanning intervals in the Monitoring settings are not available for this sensor.
The minimum scanning interval of this sensor is 5 minutes.
The recommended scanning interval of this sensor is 5 minutes.
For more information, see section Root Group Settings, section Scanning Interval.
Schedules, Dependencies, and Maintenance Window
You cannot interrupt the inheritance for schedules, dependencies, and maintenance windows. The corresponding settings from the parent objects are always active. However, you can define additional schedules, dependencies, and maintenance windows. They are active at the same time as the parent objects' settings.
For more information, see section Root Group Settings, section Schedules, Dependencies, and Maintenance Window.
For more information, see section Root Group Settings, section Access Rights.
Which channel units are available depends on the sensor type and the available parameters. If no configurable channels are available, this field shows No configurable channels.
For more information, see section Root Group Settings, section Channel Unit Configuration.
The AWS EC2 v2 sensor supports the following metrics:
- CPUCreditBalance (Average)
