This script was designed to parse the status file of the OpenVPN server installed on MS Windows operating system.
Supports 3 versions of the file status format.
There are many good scripts on Github that parse the OpenVPN status file for Unix/Linux OS. There are projects on PHP and projects in Dockers. There is an OpenVPN exporter for Prometheus. it's great!
But I had several small remote servers on MS Windows. And my task was to track connected clients without installing any components.
I will share my old school script with you.
The script is written for:
- Windows Script Host (WSH)
- VBScript
Configuring the OpenVPN server for maintaining the file status. Add to your server config file server.ovpn:
status file
status-version [n]
Where file is the path to openvpn-status.log
And status-version [n]
Set the status file format version number to n. This only affects the status file on servers with multi-client capability enabled.
1 - traditional format (default). The client list contains the following fields comma-separated: Common Name, Real Address, Bytes Received, Bytes Sent, Connected Since.
2 - a more reliable format for external processing. Compared to version 1, the client list contains some additional fields: Virtual Address, Virtual IPv6 Address, Username, Client ID, Peer ID. Future versions may extend the number of fields.
3 - identical to 2, but fields are tab-separated.
For example:
status "C:\\Program Files\\OpenVPN\\log\\openvpn-status.log"
status-version 1
The script is run in command line mode
C:\>cscript.exe ovpnstatus.vbs [status-file] [status-version]
Сan also be run without explicitly specifying CScript.exe
C:\>ovpnstatus.vbs [status-file] [status-version]
The script can receive two parameters: this is the path to the status file and the version of the status file
C:\>ovpnstatus.vbs "C:\Program Files\OpenVPN\log\openvpn-status.log" 1
The default parameters are used: status-file is: "C:\Program Files\OpenVPN\log\openvpn-status.log" status-version is: 1
