amazon web services - AWS Elastic Beanstalk: Add custom logs to CloudWatch?

How to add custom logs to CloudWatch? Defaults logs are sent but how to add a custom one?

I already added a file like this: (in .ebextensions)

files:
  "/opt/elasticbeanstalk/tasks/bundlelogs.d/applogs.conf" :
    mode: "000755"
    owner: root
    group: root
    content: |
      /var/app/current/logs/*

  "/opt/elasticbeanstalk/tasks/taillogs.d/cloud-init.conf" :
    mode: "000755"
    owner: root
    group: root
    content: |
      /var/app/current/logs/*

As I did bundlelogs.d and taillogs.d these custom logs are now tailed or retrieved from the console or web, that's nice but they don't persist and are not sent on CloudWatch.

In CloudWatch I have the defaults logs like
/aws/elasticbeanstalk/InstanceName/var/log/eb-activity.log
And I want to have another one like this
/aws/elasticbeanstalk/InstanceName/var/app/current/logs/mycustomlog.log

Both bundlelogs.d and taillogs.d are logs retrieved from management console. What you want to do is extend default logs (e.g. eb-activity.log) to CloudWatch Logs. In order to extend the log stream, you need to add another configuration under /etc/awslogs/config/. The configuration should follow the Agent Configuration file Format.

I've successfully extended my logs for my custom ubuntu/nginx/php platform. Here is my extension file FYI. Here is an official sample FYI.

In your case, it could be like

files:
  "/etc/awslogs/config/my_app_log.conf" :
    mode: "000600"
    owner: root
    group: root
    content: |
      [/var/app/current/logs/xxx.log]
      log_group_name = `{"Fn::Join":["/", ["/aws/elasticbeanstalk", { "Ref":"AWSEBEnvironmentName" }, "var/app/current/logs/xxx.log"]]}`
      log_stream_name = {instance_id}
      file = /var/app/current/logs/xxx.log*
