EC2 instance not listing all of the CloudWatch Metrics AWS shows on examples

Question

I created an EC2 instance, and we're adding Cloudwatch so we can add monitoring abilities to our servers, we're in the testing/learning phase, But now that i'm adding some metrics i' ve noticed that i do only have available 37 metrics for this EC2 instance, when you check this tutorial:

https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/viewing_metrics_with_cloudwatch.html

It clearly shows that there are 316 metrics by default On EC2

We previously identified some metrics that we want to inspect on our servers and when i tried to add them into the Dashboard i noticed they are just a few in comparison with the picture on the tutorial i 've shown above.

• Enabled detailed monitoring
• Configured the Agent on the Linux (Ubuntu instance)
• Pull the metrics via Amazon Cli to verify the qty of available metrics for me and it returns the same 37
• I added Full Control to Cloudwatch on the role i'm currently using for this EC2 instance

Any feedback, suggestion or comment will be highly appreciated,

Regards.

Answer 1

That screenshot indicates that there 316 metrics available in that particular account.

This could be 79 instances with 4 metrics each, or any combination of instances and metrics. It does not mean there are 316 metrics for each instance.
