Tool of the Day: vnstat
vnStat is a console-based network traffic monitor for Linux
and BSD that keeps a log of network traffic for the selected
interface(s). It uses the network interface statistics provided
by the kernel as information source. This means that vnStat
won't actually be sniffing any traffic and also ensures light use
of system resources. However, in Linux at least a 2.2 series
kernel is required.
features:
- quick and simple to install and get running
- gathered statistics persists through system reboots
- can monitor multiple interfaces at the same time
- several output options
- summary, hourly, daily, monthly, weekly, top 10 days
- optional png image output (using libgd)
- months can be configured to follow billing period
- light, minimal resource usage
- same low cpu usage regardless of traffic
- can be used without root permissions
- online color configuration editor
