Update: you can also find and install these tools using Homebrew
Last week I had to keep an eye on a computer’s network usage while the user was using her computer to troubleshoot something.
Initially I ssh’ed into the machine and used the common
nettop -m tcp. But still I wasn’t quite satisfied with keeping my session open and one eye continuously on the terminal.
I searched some network analytic tools for OS X but all of ‘em required compilation and some extra bits.
So that next time it is easier and faster to deploy and use this tools I have put together an installer that includes three of these tools already compiled for OS X
- bwm-ng: very simple small tool with simple UI that monitors both network and disk IO. Very useful for totals by interface
- iftop: a bit more advanced with a more detailed UI. You can see ports, sources and destinations.
- vnstat + vnstatd: useful tool to get the total usage of each interface by time. Includes the daemon but you need to build the launchDaemon yourself. It is quite easy
