hi all, I've followed the excellent https://www.howtoforge.com/tutorial/perfect-server-debian-9-nginx-bind-dovecot-ispconfig-3.1/3/ guide to get my ispConfig3 set up and running nicely. Disk quota is being tracked correctly (as far as I can tell) for mail and FTP and web space. However, I don't see any tracking of network bandwidth, nor any way to limit the bandwidth usage once (for expample) it goes over a certain amount. Am I missing the obvious documentation for this? Is there a recommended solution to use with ispConfig3? Thanks in advance for any helpful assistance and/or tips.
