This is the fourth phase of this project. This phase is a combination of three tasks. I will show every task step by step.

Task 2: Observe the amazon-cloudwatch-agent.log file

First you have to find where your amazon-cloudwatch-agent.log file locates. To find it out run following command —

sudo find / -name amazon-cloudwatch-agent.log 2>/dev/null

Then run cat command -

sudo cat /opt/aws/amazon-cloudwatch-agent/logs/amazon-cloudwatch-agent.log

You can see a log file like following image. Search “/var/log/www/error/error_log” in this file, you will see this —

Task 3: Placing order in web application and observe the CloudWatch logs

Make purchase in web application and also do some other task and then you will see all these into cloudwatch log folder.
