#### The following file installs and configures the AWS CloudWatch Logs agent to push logs to a Log | |
#### Group in CloudWatch Logs. | |
#### | |
#### The configuration below sets the logs to be pushed, the Log Group name to push the logs to and | |
#### the Log Stream name as the instance id. The following files are examples of logs that will be | |
#### streamed to CloudWatch Logs in near real time: | |
#### | |
#### /var/log/messages | |
#### /var/log/dmesg | |
#### | |
#### You can then access the CloudWatch Logs by accessing the AWS CloudWatch Console and clicking | |
#### the "Logs" link on the left. The Log Group name will follow this format: | |
#### | |
#### /aws/elasticbeanstalk/<environment name>/<full log name path> | |
#### | |
#### Please note this configuration can be used additionally to the "Log Streaming" feature: | |
