# vnStat

From ArchWiki

vnStat is a lightweight (command line) network traffic monitor. It monitors selectable interfaces and stores network traffic logs in a database for later analysis.

## Installation

Install the vnstat package.

## Configuration

Start/Enable the `vnstat.service` daemon.

Pick a preferred network interface and edit the `Interface` variable in the `/etc/vnstat.conf` accordingly. To list all interfaces available to vnstat, use `vnstat --iflist`.

To start monitoring a particular interface you must initialize a database first. Each interface needs its own database. The command to initialize one for the `eth0` interface is:

    # vnstat -u -i eth0

## Usage

Query the network traffic:

    # vnstat -q

Viewing live network traffic usage:

    # vnstat -l

To find more options, use:

    # vnstat --help
