Package: vnstat Version: 1.15-2 When using the default vnstat configuration (e.g. running the daemon with user vnstat) and running the Debian grsec kernel (linux-image-grsec-amd64), vnstatd is unable to collect any data. The user vnstat needs to be a member of the grsec-proc group.
Please add a note somewhere to inform users. p.s. upstream issue regarding no log output: https://github.com/vergoh/vnstat/issues/58
