This is a simple utility that allows you to see the load statistics of network interfaces.
You can install VnStat with the following commands:
Debian/Ubuntu
CentOS
Done. Moving on. We can configure the information in the utility’s CLI interface by configuring along the way /etc/vnstat.conf
.
For example, you can specify a network interface to be listened on by default.
VnStat saves interface statistics databases in/var/lib/vnstat
.
With the vnstat -i eth0
command we can see the total statistics (if it has accumulated) on the load of a particular interface or all, unless you specify the parameter.
Replace eth0 with the required network interface.
For example, if you want to check the current load of your server’s network channel, this command will work. Remember to specify a correct network interface.
Such output allows to determine whether the server is under DDoS-attack. High incoming traffic and a large number of incoming packets do not guarantee that this is the type of attack, but you should definitely pay attention to the protection services from DDoS.
