Stats	Statistics Notes

Some very basic anonymous statistics are recorded regarding VPN usage. The files are stored in e.g. /var/lib/vpn-server-api/stats.json.

The statistics only store information about the last 30 days, information older than that is automatically removed.

NOTE: if you have many users (connections) it may be that PHP runs out of memory when running the stats script. You can manually update the available memory in /etc/php.ini, by increasing memory_limit = 128M to something higher, e.g. 512M. To see whether this is fixed already, follow this issue.
