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.
