EC2: basic monitoring unavailable (load failed)

1. Sometimes monitoring issues arise due to network or time synchronization problems. Ensure NTP (Network Time Protocol) is correctly configured on your instance:

sudo chronyc tracking

2. Confirm that your instance has internet access to reach the CloudWatch API.
3. Check for AWS Console Service Issues. AWS occasionally has service issues. Check the AWS Service Health Dashboard to ensure there are no ongoing problems in your region, specifically with CloudWatch.
4. If the above steps don't help, create a ticket for AWS technical support https://aws.amazon.com/contact-us/

Understanding Basic Monitoring:

Basic monitoring is automatically enabled for all EC2 instances. It provides essential metrics like CPU utilization, network traffic, and disk I/O. No manual configuration is typically required.

Troubleshooting Steps:

Verify CloudWatch Service Status:

Ensure that there are no ongoing issues with the CloudWatch service. Check the AWS Service Health Dashboard: https://aws.amazon.com/premiumsupport/technology/aws-health/

Check Instance Status:

Verify that the instance is running and healthy. Check its status in the EC2 console.

Review CloudWatch Logs:

Look for any error messages or unusual activity in the CloudWatch logs related to the instance.

Inspect Instance Permissions:

Ensure that the instance has the necessary permissions to send metrics to CloudWatch. Check the IAM role associated with the instance.

Test CloudWatch Connectivity:

Try accessing other CloudWatch features (e.g., creating custom metrics) to see if the issue is specific to basic monitoring.

Check Network Configuration:

Verify that there are no firewall rules or network restrictions preventing the instance from communicating with CloudWatch.
