Elastic Beanstalk generated logs in five file by default. When cloudwatch streaming log is enabled it shows error.log access.log, eb.log. But i want catilina.out log or tomcat log also in cloudwatch log. How to do it?
You can add your own logs to Cloudwatch using an additional configuration file:
/etc/awslogs/config/awslogs.conf
As an example I use the following file to steam all the laravel logs for an application to cloudwatch:
[laravel.log]
file = /var/www/html/storage/logs/laravel*
buffer_duration = 5000
log_stream_name = {instance_id}
initial_position = start_of_file
log_group_name = prod-laravel
multi_line_start_pattern = {datetime_format}
When adding or updated the file be sure to restart the awslogs daemon too.
