This repository provides code for a simple Prometheus metrics exporter for OpenVPN. Right now it can parse files generated by OpenVPN's --status, having one of the following formats:

Client statistics,
Server statistics with --status-version 2 (comma delimited),
Server statistics with --status-version 3 (tab delimited).

As it is not uncommon to run multiple instances of OpenVPN on a single system (e.g., multiple servers, multiple clients or a mixture of both), this exporter can be configured to scrape and export the status of multiple status files, using the -openvpn.status_paths command line flag. Paths need to be comma separated.

Please refer to this utility's main() function for a full list of supported command line flags.
