To achieve the desired log segmentation structure, you can configure the CloudWatch agent to send logs to CloudWatch Logs using log groups and log streams.
Some suggestions:
Configure the CloudWatch agent on each EC2 instance using a configuration file that specifies the log file locations and log group/stream formats.
For the log group name, use the format env_name-log_type.log (e.g. prod-access.log )
For each microservice, define a log stream with the name format service_name-instance_id.log (e.g. paymentservice-i-0123456.log )
The agent will collect logs from the specified files and write them to CloudWatch Logs using the defined log groups and streams.
You can define multiple outputs in the configuration to send the same logs to other destinations like S3 if required.
Logs from all instances will be organized by service and type in the CloudWatch console for easy analysis and troubleshooting.
Let me know if any part needs more explanation or if you have additional questions!

Hi @Giovanni Lauria thanks for answering... I will create a CloudWatch configuration file within the EC2 user data script. However, I cannot guarantee that the specific service will be present on the same instance consistently, especially after restarts. There is a possibility that this service may be switched to another EC2 instance. Please advise on how to dynamically configure the log configuration file so that it sends the appropriate logs to the correct log groups whenever there is a service swap.
Furthermore, I am curious about the behavior of the CloudWatch agent if there are no logs present in the specified folder.
