Now, if OpenVPN is not running as a daemon, it will send the status to stdout; if it IS running as a daemon, it is sent to syslog.

So, you can tail your /var/log/messages and read the stats. But that’s kinda clunky and certainly not easy for people with weak shell skills. Some people who help admin my OpenVPN server are not shell savvy, so I wanted to make a utility you could use to easy display the current stats.
