Description: | |
I am starting a periodic posting for something I wanted to do since a | |
long time. Take a port in the tree and introduce it quickly. There are | |
tons of ports in the tree that we don't know about. So, I will write | |
frequently about ports that I use frequently and that I find useful, | |
if you read this, maybe I will find a new tool to your collection of | |
"useful program". :-) | |
For a first one, I would like to present **net/bwm-ng**. Its name | |
stands for “_BandWitch Monitor next-generation_”, it allows the | |
user | |
to watch in real-time the bandwith usage of the different network | |
interfaces. By default, it will update the display every 0.5 | |
second. You can change the frequency of updating by pressing keys '+' | |
and '-'. | |
Let see the bindings of the interactive mode : | |
- **'t'** will cycle between current rate, maximum peak, sum, average | |
on 30 seconds. | |
- **'n'** will cycle between data sources, on OpenBSD it defaults to | |
"getifaddrs" and you can also choose "sysctl" or "netstat -i". | |
- **'d'** will change the unit, by default it shows KB but you can | |
change to another units that suits better your current data. | |

It's available on *BSD, Linux and maybe others. | |
In OpenBSD ports tree, look for **net/bwm-ng**. | |
