AWS CloudWatch agent Troubleshooting 

AWS CloudWatch agent Troubleshooting
1) Check if Agent is running on EC2
2) Port 443 is open in EC2 Security Group
3) Check if CloudWatchAgentServerPolicy is attached to EC2
Commands:
1. Bootstrap script:
#!/bin/bash
yum update -y
2. Install the CloudWatch Agent:
sudo yum install amazon-cloudwatch-agent -y
3. Configure the CloudWatch agent:
sudo /opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-config-wizard
*** Say no to monitoring CollectD ***
*** Monitor /var/log/messages ***
4. cd /opt/aws/amazon-cloudwatch-agent/bin
/opt/aws/amazon-cloudwatch-agent/bin/config.json is the config file
5. Start the CloudWatch Agent
sudo /opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-ctl -a fetch-config -m ec2 -s -c file:/opt/aws/amazon-cloudwatch-agent/bin/config.json
6. Generate some activity on our system by installing stress - it’s in the Extra Packages for Enterprise Linux (EPEL) repository, so first we'll install the epel repository, then we'll install stress:
sudo amazon-linux-extras install epel -y
sudo yum install stress -y
stress --cpu 1
