Question: Network monitoring with vnStat

submitted 2024-03-03T19:55:33Z by tarius edited 2024-03-03T19:58:07Z

I am using vnStat to monitor network bandwidth on a Debian host that has several Docker containers. Because of the containers, there are several interfaces in addition to eth0.

My question is, should I just monitor eth0 instead of looking at all the bridge and virtual interfaces to get the actual usage because at the end of the day, everything goes through eth0? Or am I looking at this wrong?

Sample output:

``` rx / tx / total / estimated br-1ee235bc0b60: 2024-03 13.56 MiB / 97.42 MiB / 110.98 MiB / 391.02 GiB today 13.56 MiB / 97.42 MiB / 110.98 MiB / 112.54 MiB

Yes, just look at eth0. You might like the iptraf tool too.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
