You can also get rid of the entire conditional section where you're setting prog and just set prog="remote_syslog" since you're already setting the PATH below.

This became an issue for me when remote_syslog was installed to /usr/local/bin instead of /usr/bin or /opt/elasticbeanstalk/bin

The Elastic Beanstalk yum repositories currently have a version mismatch between openssl and openssl-devel that prevents this from working. To make it work you need to remove openssl-devel and remote_syslog from the packages section and explicitly install them in the commands section. You will also need to install gcc and gcc-c++.

packages:
    yum:
        rubygems: []
        ruby-devel: []
        gcc: []
        gcc-c++: []
rubygems:
    json: []

commands:
  00_downgrade_openssl:
    command: "yum -y --skip-broken downgrade openssl-1.0.1g"

  01_install_openssldevel:
    command: "yum -y install openssl-devel"

  02_install_eventmachine:
    command: "gem install eventmachine"

  03_install_remote_syslog:
    command: "gem install remote_syslog"

  04_enable_service:
    command: "/sbin/chkconfig remote_applog on"

  05_start_service:
    command: "/sbin/service remote_applog restart"
    ignoreErrors: true

Additionally, if you are running Docker in Elastic Beanstalk and wish to aggregate the console logs from your application running inside Docker, set the files property in your /etc/remote_applog.yml to:

- /var/log/eb-docker/containers/eb-current-app/*.log
