How to track, parse, visually monitor connected users via OpenVPN?

Question

PHP

Good afternoon!

To connect remote employees, OpenVPN was raised in the company.
It is necessary to monitor who and when connected from remote employees to the OpenVPN server.
Where is the log file located on the server?
How and with what to parse this log file and visually display it for the management (HR department)?

Answer 1

There is a status directive in the openvpn config - in it you can set the path to the file where openvpn will add the current information on connected connections. How to parse - FIG knows, parse it yourself, the log is simple.
In the log or log-append directives - specify the general log file, all the rest of the information from openvpn is poured there.
The logging level is set using verb.

Answer 2

Under FreeBSD, I have logs from three OpenVPN processes in /var/log/openvpnN.log
For simple monitoring, text files are written
/usr/local/etc/openvpn-statusN.log
Their format is quite simple, for example:
OpenVPN CLIENT LIST
