Установка Vnstat + webui

Quick howto для CentOS 6

# yum install vnstat -y

Редактируем файл /etc/sysconfig/vnstat

VNSTAT_OPTIONS="-u -i eth0"

В файле /etc/vnstat.conf указываем интерфейс по-умолчанию

# default interface
Interface "eth0"

Создаём базу данных для eth0 интфейса

# vnstat -u -i eth0

Error: Unable to read database "/var/lib/vnstat/eth0".
Info: -> A new database has been created.

Добавляем в автозагрузку

# chkconfig vnstat on

Запускаем

# /etc/init.d/vnstat start 
Starting vnstatd:                                          [  OK  ]

Как смотреть данные подскажет vnstat –help

Демон или cron. Информация из файла install

There are two way
 for updating interface data, daemon and cron. It is suggested to use daemon
 based updating because it generated less disk access and is more accurate
 especially when monitoring interfaces that aren't always available. Select
 ONLY ONE of these two:

 1) daemon based updating
 ::::::::::::::::::::::::

   Configure init scripts so that the following command is executed once
   during system start:

       vnstatd -d

   The examples/init.d directory contains suitable init.d scripts for
   some commonly used distributions. An alternative option is to just add
   the command to an already existing script that gets executed during
   startup. In many distributions /etc/rc.local can be used for that.

 2) cron based updating
 ::::::::::::::::::::::

   Copy the example cron file to /etc/cron.d

       cp examples/vnstat.cron /etc/cron.d/vnstat

   and edit the cron file if the default 5 minute update interval is too
   long. See the vnStat man page 'restrictions' section for limitations
   regarding fast interfaces and 32 bit interface traffic counters. Devices
   like ppp0 also require vnStat enable and disable commands to be added
   to suitable script file when cron based updating is used. Example scripts
   can be found in the 'examples' directory.

Заметки для CentOS 7 и Debian

As easy as pie. Установка, запуск, автозагрузка, проверка статуса.

# yum install vnstat
# systemctl start vnstat
# systemctl enable vnstat
Created symlink from /etc/systemd/system/multi-user.target.wants/vnstat.service to /usr/lib/systemd/system/vnstat.service.
# systemctl status vnstat

В CentOS 7 и Debian данные перестают автоматически обновляться с ошибкой Error: Unable to create database backup "/var/lib/vnstat/.eth0" из-за проблем с правами доступа.

# ls -la /var/lib/vnstat/
