OpenVPN collector

OpenVPN is an open-source commercial software that implements virtual private network techniques to create secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities.

This module will monitor one or more OpenVPN instances via Management Interface.

Requirements

OpenVPN with enabled management-interface.

Metrics

All metrics have "openvpn." prefix.

user_* stats are disabled by default, see per_user_stats in the module config file.

Metric	Scope	Dimensions	Units
active_clients	global	clients	clients
total_traffic	global	in, out	kilobits/s
user_traffic	user	in, out	kilobits/s
user_connection_time	user	time	seconds

Configuration

This collector is disabled by default. Should be explicitly enabled in go.d.conf.

Reason:

Currently, the OpenVPN daemon can at most support a single management client any one time.

We disabled it to not break other tools which uses Management Interface.

Edit the go.d/openvpn.conf configuration file using edit-config from the Netdata config directory, which is typically at /etc/netdata.

cd /etc/netdata # Replace this path with your Netdata config directory
sudo ./edit-config go.d/openvpn.conf

Needs only address of OpenVPN Management Interface. Here is an example for 2 OpenVPN instances:

jobs:
  - name: local
    address: /dev/openvpn

  - name: remote
    address: 203.0.113.10:7505

For all available options please see module configuration file.

Troubleshooting

To troubleshoot issues with the openvpn collector, run the go.d.plugin with the debug option enabled. The output should give you clues as to why the collector isn't working.

Navigate to the plugins.d directory, usually at /usr/libexec/netdata/plugins.d/. If that's not the case on your system, open netdata.conf and look for the plugins setting under [directories].
```
cd /usr/libexec/netdata/plugins.d/
```
Switch to the netdata user.
```
sudo -u netdata -s
```
Run the go.d.plugin to debug the collector:
```
./go.d.plugin -d -m openvpn
```
