Ubuntu Networking :: Traffic Monitor - How Much Data Downloaded/uploaded On An Interface This Month And Previous Month

Nov 20, 2010

I'm looking for a powerful network traffic monitor that can do all of the following (or at least a combination of tools that can do the following):

Tell me how much data was downloaded/uploaded on an interface this month and the previous month tell me how the traffic was used throughout the monthshow which internal IPs (IPs in the 192.168.1.0/24 network) used how much traffic show which ports/protocols on those IPs used all that traffic

Hhow LIVE traffic flow statistics that can tell me total speed of traffic going through an interface as well asshow which internal IPs (IPs in the 192.168.1.0/24 network) are using how much of the traffic show which ports/protocols on those IPs are using that traffic

This tool will run on a linux router through which all my internal PCs are connected to the Internet. This means the tool(s) need to work with NAT (traffic being forwarded and not necessarily destined for the interfaced being monitored).

The distribution being run doesn't have a package manager so any packages or dependencies have to be manually compiled and SCPed over file by file. For this reason, the tool/tools need to be simple (things like vnstat, not things like ntop that have their own web interface).

I know that vnstat can tell me the first bullet point so it's only there incase there's a tool out there that can do everything. If there's a tool that can only do the second or third bullet point, that's great too - I'll just keep using vnstat and look for something else to do the other task.

May 21, 2010

on the mac there is a piece of software to change the system clock so it shows the stardate instead of the month, day and year. Is there something like that for Ubuntu? I think it would be pretty cool to have a star trek themed desktop

Ubuntu :: Seems Slow In Some Areas - High CPU Usage?

Jun 15, 2010

I've been using Ubuntu consistently for about three days now. I really, really love the interface and how everything works and all that, but I've been having a couple of weird problems with speed.

Graphics things seem to work really well. When I go into the overview of all my workspaces, it's instant and looks great. The problem is when I open and use some applications.

For example, when I open up the software center, it takes longer than it did the first time to start up. Also, when I drag windows off from being maximized, it takes literally about five seconds for it to show up as being dragged around by my mouse.

When I look at the system monitor, about 20% of my CPU cores are constantly being used. That's 20% each. I have a 3-core CPU, could that be the problem?

Another example: when I went to ..... just now, it would take a second for any volume changes in the video to register.

And I also have smooth scrolling in firefox, but it's very unresponsive now. It's slow as all hell. Even notifications are showing up more slowly.

So, what's the deal? What could I have done wrong?

CPU: AMD Phenom II X3 2.8Ghz
GPU: ATI Radeon HD 4860 1gb
RAM: 4gb

One more thing: I have really bad screen tearing when I try to move windows around, as if there isn't any vsync on. Where can I turn it on or fix this?

I'm still pretty new to Ubuntu and Linux, but I'm an advanced computer user. Since I feel linux is killing my CPU I think I'm going to boot back into Windows 7 for now, but if I can fix this problem I think I want to keep Ubuntu as my main OS after this, having Windows for games, unless I can get Wine to work right with them.

Ubuntu :: USB Disk - Slow Transfer Speeds And Slow System?

Apr 17, 2011

Whenever I transfer a movie into my 16GB USB flash disk, my whole system becomes windows-like and unusable!

When i drag the file(s) into the USB disk folder, it starts out fine and pretty darn fast (25mb/sec) then slowly decreases until it's unbearably slow (3m/sec) and as a side effect my whole system starts deteriorating. I basically have to wait for the file to finish transferring before i can use my desktop again!

This has been happening with every version since Karmic (all 64bit)- I put up with it because I don't use the USB stick that much.. but lately it's been my go to source for transfering large files to/from work.

Ubuntu :: System Monitor CPU Usage Does Not Add Up?

Apr 22, 2010

quite often my computer will slow down, and all the cpu indicators will show 100%. However, when I open System Monitor to see what is using all the CPU, it doesn't show anything much at all. I have attached a screenshot to show what I mean. CPU is running at 91% load, however, I make the total 35% in system monitor.

Ubuntu :: 10.10 - CPU Usage In System Monitor

Jan 6, 2011

I am having a slight issue with my netbook (toshiba nb305) Just fully switched to Ubuntu 10.10 from Windows 7 starter so still a little new. I first installed the 32 bit version and everything was all sorts of peachy. But while reading some documentation on my model I ran across a cryptic line that hinted at my cpu being 64 bit. Did a little research on these forums and ran a command in terminal (honestly cant remember it) that listed the specs on my hardware. Sure enough my "width" was listed as 64 bit.

Well just to give it a shot I Downloaded the 64 bit version of 10.10 and Installed it on another partition. Up and running checked over everything. Appears to be normal. But on a whim I went into the System Monitor and noticed not one cpu but 2? Confirmed same situation on 32 bit.
Processor 0: Intel(R) Atom(TM) CPU N455 @ 1.66 GHz
Processor 1: Intel(R) Atom(TM) CPU N455 @ 1.66 GHz

Ok I was a tad bit confused so I was about to do a lil research on it. But then I noticed on the Resources tab that under 64 bit my CPU History graph showed both processors Pegged at 100% With nothing running except for the basics. Under the 32 bit it was reliantly low? I checked the Processes tab in both to confirm there wasnt a unusual process out there jamming up cpu usage but the highest cup listed was the gnome-system-monitor at like 40 est %. Nothing showing up using the CPU that vigorously.

Ubuntu :: Using System Monitor To Watch Cpu Usage?

May 1, 2010

Transmission seems to cause a kernel panic when I try to use it. Using system monitor to watch cpu usage, as soon as I fire up transmission, the cpu usage spikes to 99 and 100 percent and the transmission window grays out. I set firestarter to allow bit torrent usage, I was wondering if there was something else I needed to do or if transmission was broken. I am running an Athalon 3200 on an MSI motherboard with 2 gigs of ram.

Ubuntu :: CPU Usage In System Monitor - Not Hardware

Nov 2, 2010

I had been running Folding@Home as a distinct process when I was running Windows - I'd manually start and stop it. (This was intentional.) I just installed it on my Ubuntu 10.04 install, and it's running just fine.

The only thing that's strange is that while top and the System Monitor report the CPU usage correctly, the Hardware Monitor applet (1.4.2) isn't reporting the usage at all.

As I said, it's an annoyance, nothing more - the applet reports other CPU usage accurately, and Folding@Home runs smoothly and perfectly.

Gnome's Hardware Monitor applet (1.4.2), the one with "curves" and "flames", apparently displays both "user" and "system" processes. Processes marked "nice" (that is, only running when the machine is idle) do not appear as CPU usage. They do appear as CPU usage in the System Monitor applet.

Ubuntu :: System Monitor Not Correlating With Memory Usage?

Feb 1, 2010

in this example, my memory 993.4 MiB memory is said to have 575.9 MiB of it used and 163.4MiB of my 2.8 GiB swap memory used. but in my processes tab, the most memory hogging program is 98.3 MiB, and Pidgin, 25.9 MiB, and 18.9 MiB, 14.9, 6.2,6.1,5.2,3.4,3.3,1.8,1.8,1.7, etc. I'm certain these don't add up to 575.9 MiB so where is all this extra memory usage coming from?

also, why is data measured in MiB?

Ubuntu :: System Intermittently Freezing - Usage Python

Nov 30, 2010

I have a bit of mystery regarding my system intermittently freezing. First off, the info. I using/running: Ubuntu 10.10, 64bit version (clean installation) Intel(R) Core(TM)2 Duo CPU E8500 @ 3.16GHz (not overclocked) 6GB RAM Nvidia GTX260 Nvidia proprietary drivers 1TB Western Digital HD (32MB cache) Now, the problem: A while ago, I started experiencing intermittent system freezes that would last for 2 or 3 minutes and happen about once every 45 to 75 minutes.

The Gnome System Monitor (GSM) would show 100% CPU utilization, but top, htop, and conky only show about 11% usage. I pulled up the process list in GSM. However, I had issues, for the obvious reason, when bringing it up when the CPU was spiking. Even when I could, it only showed the usual suspects (Firefox, Deluge, Ktorrent, and Xorg) running the high single digits. This was backed up in top, htop, and conky. I also checked the RAM, but usage was down around 25%, with nothing in the swap.

I checked the messages log, but there was nothing there. Nor in dmesg. At least not that my limited Linux admin skills could find. The freeze just happened, so I've attached them in their entirety. I've come to suspect that Python is the cause. It happens most often when I have Ktorrent or Deluge going. I used to use Deluge, but moved to Ktorrent to test if Deluge itself was the problem. They're both written in python though, and both seem to cause the slowdown. It also happens when other python-based programs are running, such as the updater, but not as much or as bad. Things I've tried to fix the problem:

- Clean install (first time in over 18 months)
- Updated Nvidia driver by adding a repository
- Updated Deluge by adding a repository
- Enabled backports.
- Gave my PC the finger

This is driving me nuts. If it was just BT clients, I'd only run those at nights, but it's also parts of Ubuntu itself that relies on python, which I really think is the problem.

Ubuntu :: Prevent System Freeze Due To High RAM Or CPU Usage

May 1, 2011

I have been using ubuntu for 4 years now on my decent laptop with 2 Gb RAM, dual core centrino, etc etc. Yet, in all those years I have been using this superior OS, I still have to do hard shutdowns because some program runs wild. I have lately 2 scenarios where I have to interfere with the process:

1: amarok crashes and leaves the python script for the gnome shortcut keys running at 100% CPU. Or: thunderbird-bin keeps running after apparently clean close of Thunderbird. That's not really bothering me, I just kill both processes.

The bigger problem is scenario 2: 2: VLC starts eating all my RAM (for no reason), my SWAP starts filling and my computer becomes unusable for 10 minutes. Or: my matlab script is too big and eats up too much RAM -> same. Note: I have nothing against SWAP because at many other times it's very useful

These are stupid and annoying problems where there is an easy solution:

1) automatically kill the stupid process that runs at 100% CPU
2) automatically kill the stupid process that eats up all my RAM

Ubuntu :: Memory Usage - Top Doesn't Match System Monitor?

Aug 3, 2011

running top shows:
Tasks: 165 total, 1 running, 164 sleeping, 0 stopped, 0 zombie
Cpu(s): 3.5%us, 2.2%sy, 0.0%ni, 93.9%id, 0.5%wa, 0.0%hi, 0.0%si, 0.0%st
Mem: 3721884k total, 3376604k used, 345280k free, 107524k buffers
Swap: 3855356k total, 40k used, 3855316k free, 2013536k cached

but System Monitor tells me that only 33.9% (1.2gb of 3.5gb) is being used. Why is the memory used difference so great?

Debian :: Memory Usage On A Squeeze System?

Mar 16, 2011

I use a Debian Squeeze system running off a flash drive, i.e. based on a custom Live image running in persistent mode. It runs great and I am grateful for the existence of Debian . However, I have a question. A lot of the machines I use this pen drive on are quite old, often with 512 MB RAM and old processors. I specifically built my system using XFCE and lightweight apps off an initial live image using the standard-x11 package list (basically just Xorg with drivers and the base system). At first things ran very well, blazing fast even on the oldest systems and could comfortably run Firefox along with LibreOffice side by side (I need LO as all of my colleagues use Word docs, often with track changes, which Abiword can't handle properly). However, over time, I've found that memory usage has risen, tot he point where Firefox is now automatically killed on the older systems every time I start LibreOffice.how does one figure out why memory usage is going up? I've checked for inessential services and turned them off with "insserv -r". I've used only lightweight apps, as mentioned before. Are there other general tips on reducing memory usage?

General :: Diagnosing Heavy Cpu System Usage?

Jul 26, 2011

I have been encountering lots of heavy system cpu usage. It is sporadic, last for about 10 minutes, and brings everything else to crawl (latency of even typing characters into an editor or a terminal is painfully slow). My computer is an i7 quad, and all 8 logical cores fire at near 100% during these periods. I can see the usage clearly with htop. The red bars in htop indicate system use (I have attached a screen shot for an example). However, as there is no process per se, I have no clue what is causing it.

It is something I have to fix as the computer becomes unusable periodically throughout the day.I One thing to add, I am using the computer as a ltsp server on ubuntu, attaching to it using two thin clients. There is always heavy ethernet traffic through the second ethernet card. I don't know if this is related. However, I do think all this problem began when I installed the ltsp and switched to using a thin client.
