Use the Task Manager to See Current Usage
Feb 16, · NetBalancer is quite handy for peeking in at what applications are using your bandwidth but the original purpose of the application wasn’t to merely watch. NetBalancer was designed to help you balance the load on your likedatingus.com: Jason Fitzpatrick. Dec 24, · Here's how to use it: Step 1: Start by opening the Resource Monitor. Although this can be done several different ways, the fastest way is to head to Start > Run > type resmon and press enter. It has to run as root but there are different ways you can sort the statistics (like KB/s or total bandwidth monitored since nethogs started). Also, if you use wireless you need to pass the device to it. Install it with command: sudo apt-get install nethogs. Example: sudo nethogs wlan0.

I think I'm being the victim of a bug here. This sometimes happens to me with the CPU usage. When it does, I just run a top command to find out which process is responsible and then kill it. Problem is: I have no way of knowing which process is responsible for my high network usage.
Both the resource monitor and the top command only tell me my total network usage, neither of them tells me process specific network info. I've found questions here about monitoring total bandwidth usage, but, as I mentioned, that's not what I need. Is there another command I can use to find out which process is getting out of hand?
The command iftop gives results that disagree entirely with the information reported by System Monitor. I've already tried killing all the obvious ones Firefox, update-manager, Pidgin, etc with no luck. So far, restarting the machine is the only way I found of getting rid of the issue. I've had a lot of success with nethogs.
Use iftop to locate the TCP port on your machine that is receiving the most traffic. Then use sudo netstat -tup to locate the process "owning" that port. You might want to look into ntop - which should monitor network activity on a process level. You can find ntop in the Software Center or with sudo apt-get install ntop. Another alternative is iptraf. It won't show you the PID of the process, but will tell you which connection uses how much bandwidth. Late answer, but I had the same problem.
Turned out to be Ubuntuone. Found that by running tcpdump. I went through the same learning curve on process identification. From my notes :. Started up my Ubuntu So, I needed to investigate Editor's note: This answer was referring to tinker's blogspot article which is meant for invited users only.
Since this answer has appreciable upvotes, so it is valuable. I found a copy of article on Wayback Machine. And included that here. Here's one I like, it tells you what's reading from the network the most, anyway doesn't seem to work for which one is "writing to" the network, so Ubuntu Community Ask!

It's been a while, but this answer is considerably simpler indeed. Be warned of a bug making some versions of nethog unusable: askubuntu. You don't need to pass the device if you're using wireless.

I'm accepting the answer since it does answer the original question. But I'll be nice if I can figure out what's going on here. I'm not sure if System monitor looks at only one interface or all of them.
If that's the case then there will be traffic shown by System monitor but not shown by iftop, which is OK because you only want to be looking at your internet interface anyway and not lo. I just tested iftop on my system and it showed what I expected it to. Be aware though that iftop displays averages over 2s,10s,40s respectively.
I ran iftop like 'sudo iftop -i eth0 -nPB', how did you run it? I ran it as sudo iftop -B -i eth0 , that means it was only looking at my internet traffic right? It didn't occur to me that the system monitor might be checking other interfaces as well. Ironically, the problem disappeared 10 minutes ago after many hours , so I can't check iftop again for now.
What does the lo interface stand for? Since there are a lot of numbers on the iftop screen I've created a screenshot where I highlited the number you're interested in. Compare that to System monitor.
The screenshot is at imgur. Show 2 more comments. Anwar It has its own local server, and is sooo confusing Dennis Kaarsemaker Dennis Kaarsemaker 6, 21 21 silver badges 36 36 bronze badges. From my notes : Ubuntu box connection information Started up my Ubuntu Shows Ubuntuone going crazy.
Turn all synchronization off. That did it. So, I'm thinking I'd like to see all network connections and what they're doing. I can netstat -cW list network connections continuously in wide format so foreign addresses aren't truncated lsof -i grep -v 'localhost' list open files matching an Internet address of any, grep to remove any open files associated with localhost -- my thought here being that I don't want to see local services as they likely will not affect network utilization.
Some things to take away: Need to learn about Ubuntu logs for troubleshooting. Need to learn more about tcpdump, so I'll start with this tutorial by Daniel Miessler.
