What is OpenVPN Monitor?

OpenVPN Monitor is a web-based utility that displays the status of OpenVPN servers. It includes information such as the usernames/hostnames connected, remote and VPN IP addresses, approximate locations (using GeoIP), traffic consumption and more.


First, make sure OpenVPN is configured to open the management interface that the OpenVPN Monitor connects to. Edit the openvpn.conf file and add the following directive (choose port 5555 or any other of your preference):

management 5555

All settings of OpenVPN Monitor can be dynamically configured via environment variables (thanks to confd) without having to create a new image or bind-mounting the configuration file.

The environment variable are organized into two groups:

  • OPENVPNMONITOR_DEFAULT_<PROPERTY>: populates the global [OpenVPN-Monitor] section.
  • OPENVPNMONITOR_SITES_<INDEX>_<PROPERTY>: populates each site section.

By default, GeoIP is automatically available (no additional download step is required). For this reason, the location of the geoip_data file is hardcoded in the configuration file. The datetime_format defaults to %d/%m/%Y %H:%M:%S if none is provided. Everything else must be set and there is not whitelist of property names. This ensures compatibility of this image with future versions of OpenVPN monitor without too much maintenance.

So a minimal and accessible, yet non-functional, version of OpenVPN Monitor can be reduced to:

docker run -p 80:80 --rm ruimarinho/openvpn-monitor

Let's add some configuration, including changing the page name, adding a logo, some geolocation features and two sites - one that connects to a running TCP OpenVPN server and another one to an UDP server.

Using the scheme above, the configuration is as simple as setting the appropriate environment variables:

docker run --name openvpn-monitor \
  -e OPENVPNMONITOR_SITES_0_HOST=openvpn-udp \
  -e OPENVPNMONITOR_SITES_1_HOST=openvpn-udp \
  -p 80:80 ruimarinho/openvpn-monitor

Now OpenVPN Monitor should be accessible via

Note that for the logo.jpg to be readable, you need to bind-mount it or pass an URL instead. Also, the datetime format needs to be escaped as shown above (suing two %).

Supported Docker versions

This image is officially supported on Docker version 1.12, with support for older versions provided on a best-effort basis.
