OpenVPN offers several options to monitor the clients connected to a server. The most commonly used method is using a status file. The OpenVPN status file is continually updated by the OpenVPN process and contains the following information:
Which clients are connected
- From which IP address the clients are connecting
- The number of bytes each client has received and transferred
- The time at which the client connected
- In addition, the routing table also shows which networks are routed to each client
status /var/run/openvpn.status 3
The second parameter to the status option is the interval after which the status file is updated (rewritten). The default value is 60 seconds.
