I am trying to see how much disk space my log files are using, but when in the CLI and browsing to the log directory: /var/log/gragraylog/server, I can only get to the graylog directory, and when trying to cd to the /server directory, I get a Permission denied message. I have tried to su cd/server, but I am prompted for a password, but I don’t know what the password is. As of now, all my passwords are the default ones since I am only testing the app. I want to be able to keep my eye on the log size so I can know how much storage to plan for when I roll this into production. So, I guess what I need to know is what is the default su password for a graylog instance.
