Explanation
The status parameter in an OpenVPN server configuration file specifies the name of a file where OpenVPN writes information about the current status of the VPN tunnel, such as the time, bytes sent and received, and the IP address and port of each connected client. This file can be used to monitor the VPN activity and troubleshoot any issues. The file does not contain any information about errors and warnings generated by the openvpn daemon, as those are written to the log file specified by the log or log-append parameter. The file also does not contain any historical information about the clients who have connected at some point, as it only shows the current state of the VPN tunnel.
