    In this lab, I get this message in my working terminal and the terminal showing the fluentd running logs

      I reran that same command with your config and it seems to work for me.

      Can you try stopping the fluentd process then start it again?

      thank you. i figured out what happened. i got timed out from my terminal and had to re-login. i forgot to redo this step
      ~/labsys$ export FLUENT_CONF=/home/ubuntu/labsys/lab2/lab2.conf
      after recreating the env variable, it worked.
