Amazon CloudWatch agent

• This agent is an application that runs as a daemon or background application that collects and sends the logs to cloud watch
• Lets create an amazon linux ec2 instance and configure the cloudwatch agent
• Install Cloud watch agent Refer Here
  sudo yum install amazon-cloudwatch-agent -y
sudo /opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-config-wizard
• Refer Here for log agent configuration
• Once we run the wizard and then try to answer questions then a config file will be created at /opt/aws/amazon-cloudwatch-agent/bin/config.json
  
• For this ec2 instance to send logs to AWS we need to give permissions
• Create an IAM Role => This is applicable to ec2 instances only
• Create an IAM user and configure this => This can be done for ec2 instances as well as on-premises instances
• Lets create an IAM Role
  
  
  
  
  
  
  
• Now lets apply this role to the ec2 instance
  
  
• Now lets install httpd on this ec2 instance
  sudo yum install httpd -y
sudo systemctl enable httpd.service
sudo systemctl start httpd.service
• Now start the cloud watch agent
  sudo amazon-cloudwatch-agent-ctl -a start
• Try to write some shell which will continuously access your apache server
  bash
apache_url='http://34.209.194.214'
while true
do
curl ${apache_url}
sleep 5
done
• Next Steps: Lets troubleshoot the issue w.r.t to log streams not getting created.
