OpenVPN Monitor

Simple script to monitor usage stats (received/sent bytes) of OpenVPN per user (name+ip+port) with easy setup and no dependencies (except bash, awk and nohup)

Example

Setup

Add next to config of OpenVPN (e.g. /etc/openvpn/server/server.conf):

status openvpn-status.log
status-version 2

Launch Monitoring

nohup ./openvpn-monitor.sh --status-log=/etc/openvpn/server/openvpn-status.log --stats=/etc/openvpn/server/openvpn-stats.log &

Note: nohup.out is empty, log is printed to extra log file.
