Network monitoring tool

March 5, 2009

Today I wanted to monitor the network usage on my Linux box. Compared to what most bandwidth monitoring tools do I wanted to monitor the bandwidth per process - usually most Linux tools tools just monitor the bandwidth per interface. And I realized that is actually a very rare thing on a Linux system to monitor the network per process.

But suddenly I remembered an article I read some time ago about a network monitoring tool that calculated the bandwidth usage per process. It looked something like top but for network usage and per process. It wasn't however very easy to find again and it took a rather long time before I eventually found it again. So for future references I decided to write a blog entry about it.

The tool is called NetHogs and is available for installation in any ordinary Linux system by default.
