<a name="monitoring"></a>

Monitoring is an important part of maintaining the reliability, availability, and performance of your AWS Deep Learning AMIs instance and your other AWS solutions. Your DLAMI instance comes with several GPU monitoring tools, including a utility that reports GPU usage statistics to Amazon CloudWatch. For more information, see [GPU Monitoring and Optimization](tutorial-gpu.md), and see [Monitor Amazon EC2 resources](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/monitoring_ec2.html) in the *Amazon EC2 User Guide*.

The following AWS Deep Learning AMIs operating system distributions include code that allows AWS to collect instance type, instance ID, DLAMI type, and OS information.

**Note**  
AWS doesn't collect or retain any other information about the DLAMI, such as the commands that you use within the DLAMI.
+ Amazon Linux 2
+ Amazon Linux 2023
+ Ubuntu 20.04
+ Ubuntu 22.04

**To opt out of usage tracking**

If you choose, you can opt out of usage tracking for a new DLAMI instance. To opt out, you must add a tag to your Amazon EC2 instance during launch. The tag should use the key `OPT_OUT_TRACKING` with the associated value set to `true`. For more information, see [Tag your Amazon EC2 resources](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Using_Tags.html) in the *Amazon EC2 User Guide*.
