Use Fluentd via the Command Line

In this lab, you will be provided with a server that has Fluentd preinstalled for you. The purpose of this lab is to have you create a separate Fluentd configuration file that will send `syslog` output to the Fluentd stdout. This configuration file will be used via the command line. Once created, you will test that it is directing log entries to Fluentd.
