Is there a way to get a summary of how much bandwidth a given process used on Linux after the process completes? I do not want a monitor, I want something I can look at after the task has completed..
Ideally something like the "time" command or a profiler, but for network usage.
I'm looking for some utility that will measure my network bandwidth use and report it in ways that are human readable. Specifically, I want something that I can use to stay ahead of my mobile broadband plan's usage metering.
View 2 Replies View RelatedI have a proxy/gateway server with X routable addresses and X clients, each connecting to his corresponding address from my server. All clients have public static IP's. I need something like the output of 'pktstat -1 -w 10 -B -i eth0 -n -P -t -T' but that would indicate the biggest'traffic hogs' from my clients.
Something like:
67.78.89.90 <-> my.public.ip.1 1344KB/s up 289KB/s down
56.67.78.89 <-> my.public.ip.2 1203KB/s up 200KB/s down
With this output, I can limit the traffic passing thru my server using a bandwidth limiter on my.public.ip.1 and my.public.ip.2. Pktstat only shows the total traffic from-to the respective IP's gathered in a 10second interval (-w 10). I would like something that would indicate the bandwidth per ip more precisely, I don't want to divide the total traffic by 10 (seconds).
Please note that this will go in a cron job. The interactive tools like iftop are useless (I would like something like a text screenshot of iftop from which I could extract the needed information).
I am wondering if there is a tool that measures bandwidth speed right from the shell on CentOS 5.4/5.5.
I am looking for a speed tool rather than go ahead and download a large file and time it sort of advice.
Please let me know if this is available.
P.S. It is to measure the internet speed from the ISP and not the LAN speed.
On occasion I see my bandwidth usage using the gnome system monitor going up to 300kbit/s. I just cant figure out what is causing it. I want to know what process or program in using my network like that? I do ssh into different machines and servers, where I would really like to beable to monitor bandwidth usage. It would be very useful to know which utilities people use to see what bandwidth is being used and by which applications / programs / processes / or threads. I don't even know where to start looking. The two small programs I have found are insufficient. bmon and bwm-ng. And tools like wireshark (packet sniffers) are over kill. I would like some thing in the middle, preferably text console based.

Platform is Ubuntu 8.04 LTS.
I have scripts in /home/useraccount/bin/
running
crontab -l
While logged in as user results in:
# m h dom mon dow command
@hourly /home/useraccount/bin/script_1
@hourly /home/locateruser/bin/script_2
I realize scripts could send email or write to a log with a timestamp, but wondering if there is just a way to verify it ran from the command line.
I ran
ps -ef|grep cron
... and it shows
root 4358 1 0 Mar12 ? 00:00:00 /usr/sbin/cron
Not sure if this indicates it is running the jobs though....
My question is not related to technical one,
1.I completed my Post Graduation in 2008,after that as of my personal interest on Red Hat, i took course on that and completed the RHCE certification.
2.Now im looking 4 opportunities on Linux Admin,i would like to know the roles played by an Linux Admin in real time scenario,im looking for an System Admin.
3.What i mean to ask is, what type of daily tasks does Linux Admin will do? Let me know the answers if any one know dis.
For example I am copying data to USB-flash drive using some file manager. When the file manager shows that transfer is complete, flash drive indicator continues to light. As far as I know this is some kind of caching system...
1. Is it OK to close file manager when transfer window is closed but the flash drive indicator continues to light (data is still being copied)?
2. Is it better if I turn off this caching technology?
I created a the class like this for shaping the packets with a specified bandwidth rate.....
tc qdisc del dev eth0 root
tc qdisc add dev eth0 root handle 1: htb default 15
tc class add dev eth0 parent 1:0 classid 1:1 htb rate 750kbit ceil 750kbit
tc class add dev eth0 parent 1:1 classid 1:3 htb rate 600kbit ceil 750kbit prio 0
For Our Requirement:-
I dont want to specify the bandwidth rate strictly like this rate750kbit ceil 750kbit,based on whatever speed is coming which should allocate the bandwidth rate for particular class...I need one application for finding the upcoming bandwidth & Is any other method is there for specify the bandwidth rate in a classes.

I want to measure the startup time of any GUI app (e.g. firefox) using the time(1) command. However, timing is measured until the app is closed, which has to be done manually by exiting it or clicking X.

[code]....
Description of what the code does or what i intended to do:
1. Created a child process from parent process using 'fork()'
2. Sent a signal 'SIGALRM' from child process to parent process using 'sigqueue' function.
(The Third parameter of 'siqueue' function contains the message (message msg) which the child process wants to send to the parent process.'msg' is a stucture instance containing a) pid of child and b) string) 5. Print the 'msg' sent by child process inside the signal handler function 'sig_action_function' of the parent process I am getting some junk value when this line is executed
Code:
printf("%d
",msg->cpid);
I expected to get the pid of child process, which the child process sent to parent process through the signal.
We have a sipmle office network set up that we also use use to connect to the internet, however of late the number of users has increased thus slowing internet access. Bandwidth upgrade is not an option thus i have to do bandwidth shaping on our linux router. The question is how do set the squid configs to allow certain IP's range a certain percentage bandwidtheg 60% and furthe divide the rest. Alternatively how can allow certain IPs to have higher bandwidth access.
View 1 Replies View Relatedas we all know Process Scheduler does Process scheduling and its a process as well. I was just wondering that if this happens then the Process "Process Scheduler" should be a part of Process queue as well.
So if there are 5 process are there in Process queue & process scheduler is administrating them then since its also a process, once it puts a process under RUN state it should itself go inside queue because at one instant only one process can get executed on a processor. This is quite confusing for me. Please help me out. I tried to search on this but could not find any relevant topics.
