Edit the CloudWatch Agent Configuration File: Locate the CloudWatch Agent configuration file on your EC2 instance. This file is typically located at /opt/aws/amazon-cloudwatch-agent/etc/amazon-cloudwatch-agent.json. Edit this file using a text editor.
- Add EC2 Metrics Configuration: Within the configuration file, you'll need to add a section to specify which EC2 metrics you want to collect. Here's an example configuration for collecting basic EC2 metrics: { "metrics": { "append_dimensions": { "AutoScalingGroupName": "${aws:AutoScalingGroupName}", "ImageId": "${aws:ImageId}", "InstanceId": "${aws:InstanceId}", "InstanceType": "${aws:InstanceType}" }, "metrics_collected": { "cpu": { "measurement": [ "cpu_usage_idle", "cpu_usage_iowait", "cpu_usage_user", "cpu_usage_system" ], "metrics_collection_interval": 60, "totalcpu": false }, "disk": { "measurement": [ "used_percent", "inodes_free" ], "metrics_collection_interval": 60, "resources": [ "" ] }, "diskio": { "measurement": [ "io_time" ], "metrics_collection_interval": 60, "resources": [ "" ] }, "mem": { "measurement": [ "mem_used_percent" ], "metrics_collection_interval": 60 } } } } This configuration collects CPU, disk, disk I/O, and memory metrics for your EC2 instances.

Specify the Region: Ensure that the CloudWatch agent is configured to send metrics to the correct AWS region. In your case, you've already configured it for the us-gov-west-1 region, so you don't need to change this.

Restart the CloudWatch Agent: After making changes to the configuration file, restart the CloudWatch Agent to apply the new configuration. You can typically do this with a command like:
sudo /opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-ctl -a fetch-config -m ec2 -c file:/opt/aws/amazon-cloudwatch-agent/etc/amazon-cloudwatch-agent.json -s Replace /opt/aws/amazon-cloudwatch-agent/etc/amazon-cloudwatch-agent.json with the path to your actual configuration file if it's different.
After performing these steps, the CloudWatch Agent should start collecting EC2 metrics and sending them to the specified region. You can then view these metrics in the CloudWatch console.
I configured the credentials with a role in the GovCloud region. Metrics cannot be uploaded to GovCloud, but logs can be uploaded to the GovCloud region. My idea is to collect EC2 metrics in the current non-GovCloud region while also being able to upload custom logs to GovCloud region's CloudWatch. How should I configure the amazon-cloudwatch-agent.json? Is this okay? For example: { "agent": { "metrics_collection_interval": 10, "region": "us-east-1", "logfile": "/opt/aws/amazon-cloudwatch-agent/logs/amazon-cloudwatch-agent.log" }, "aws_credentials": { "access_key": "your-access-key", "secret_key": "your-secret-key" }, "metrics": { "namespace": "YourNamespace", "metrics_collected": { "cpu": { "measurement": [ "cpu_usage_idle", "cpu_usage_iowait" ], "metrics_collection_interval": 10 } } }, "logs": { "logs_collected": { "files": { "collect_list": [ { "file_path": "/var/log/myapp.log", "log_group_name": "my-log-group", "log_stream_name": "my-log-stream", "timezone": "UTC" } ] } }, "log_stream_name": "testLogStream", "force_flush_interval": 15, "region": "us-gov-west-1" } }
