Hi Meghana, You're getting an access denied exception, so there's most likely an issue with file permissions. I'm guessing it's the config file `logstash-sample.conf`. Can you check and update the permissions of your config file and make sure it's readable before rerunning the command? ---

Please rename /usr/share/logstash/data/.lock ---
