Linux: Is there something similar to "top" for I/O?

I am trying to do some CPU intensive operation on a Linux machine and it is showing very high load.

I want to figure out if this load is due to I/O or CPU usage. How could I get the percentage of I/O usage by process?

Slackware :: Unable To Kill Java Process With Average 90% Cpu Usage?

May 11, 2010

I have a java process running in background. I have no java dependent program opened and even if I had, this program should be killed if I kill the Java process. top shows that Java causes almost 90% cpu usage.

[Code]...

The only way I can imagine is to restart, but this might happen again.

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

Aug 3, 2011

running top shows:

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?

General :: CPU Usage Of Process

Jul 15, 2011

I am currently writing a JAVA script to monitor certain unix processes through JConsole. Upon having lots of trouble with runtime.exec, i decided to bypass the top/ps command call and just get the information straight from /proc/*pid*/whatever.Now i can pull back any information from any of the files I want, and the current way i determine the CPU usage of a process is as follows:Add the UTime and STime of that process from /proc/pid/stat then divide my pidCpu by UTime + STime + NTime from /proc/stat, then multiply that by 100, should give me the % cpu usage a process is using, right?Theory being if I get the jiffies assigned to my process, I can divide that by the total jiffies the cpu assigns.

However, my results seem to vary from the ones gathered from top and ps. What am I doing wrong?

General :: Way To Limit CPU Usage For Some Process?

Sep 21, 2009

I'm writing a shell script which aims to create a safe gtared (xxx.sql.gz) copy of MySQL databases.This script is planned to be Cron-Jobed.

Well, what I need to add to this shell, is something that limit CPU usage for the whole process (just in case if the database being generating is a huge one.)So, after few time of googling I found couple of solutions:

- Using cpulimit.
I tried to place the code in Position(1) and Position(2) but it didn't seem to be working fine.. Any idea about the right use?

And the other Solution is:- Using nice.

Well, assuming I named my shell script (sqlbacker)..

Finally, this is my first time I ever write a shell, so correct me if somewhere I made a mistake :-)
(The script itself works perfectly)

General :: Need To Limit CPU Usage Of Process

Jan 26, 2010

There's a disfunctional process eating copious cpu time.Is there a way to effectively assign it a high nice value? I need to do this whenever it runs, for whatever reason, and I can't be bothered to track down all the scripts and scenarios that cause it to run and change the script to use nice. And I can't be bothered to manually run renice whenever I notice that it's running.

I want the OS to automatically assign a high nice value to this process, perhaps based on the processes name. Is this possible?Presumably, a cron job could run every 5 minutes and run "renice" on every process matching a given name, but I'm hoping for a solution with more finess.

General :: Big Cpu Usage But Top Shows No Heavy Use Process

May 6, 2011

I have been running to a strange problem. For a few days, a few times a day something seems to take over my machine. Suddenly I can't type, or the key shows up about 5 seconds are being pressed, music players halt, etc. In anticipation, I had top and htop running. Sure enough, when this business begins htop reports all 8 cores firing at near 100% for a few minutes. However, top is telling me nothing about who is too blame. The cup%sy on top shows heavy usage, but the top processes are nothing remarkable, mostly just top and htop and conky, all running at around 1 or 2% on average. I am a bit puzzled as to why I can't see the cpu hog so that I figure out what is going on. My question then: Are there some processes (in kernel space?) that don't show up in top, yet which could be hogging the cpu?

General :: Display Processes % Usage But Only Want The Process Name And % Used?

Sep 14, 2010

I have to monitor the %MEM that processes are using, so I use the ps and sort command like this ....

ps -aux | sort -nk4

So this will sort by column 4 so I can see the all the processes that are using the highest %MEM. What I really want is to be able to just display the process name and the %MEM next to it. how to do this?

General :: Calculating Process Memory Usage?

May 13, 2010

What originally seemed like an easy thing to calculate has given me a big headache. Perhaps someone can help me with my issue. I am trying to find, in particular, how much memory certain application processes are taking. The process always is the same name, main_server, but with an argument to tell it what to do when running as a daemon.

When running the following command against all "main_server" processes, it produces a result in megabytes based on the output of the rss field in 'ps'.

Code:
CALC=0
for ea in
`ps -e -orss=,args= |
sort -b -k1,1n |
pr -TW$COLUMNS |
grep main_server |
grep -v "grep main_server" |

[Code]...

Currently I am left scratching my head. For capacity planning purposes, it would be nice to know how many more 'main_server' processes could run on the system without causing it to swap. Knowing the buffer and cache usage will go down as running processes demand more memory, I prefer to look at the free memory excluding cache and buffers. However, since 'ps' is reporting the processes are using more memory than free reports is in use without those things, I have no way to know how many more processes the system can support. I played around with different fields in 'ps', such as vsize, size, etc, but with no luck in matching up any numbers.

General :: How To Monitor CPU / RAM Usage And Top Processes

Mar 18, 2010

I have a question. I want to monitor
- CPU usage daily
- RAM usage daily
- Harddisk Space
- top processes
- hardware failure

What commands do I need to run to output the result to a log file? I know there are solutions both paid and free, but my company does not allow. they want linux built in commands or methods to do it. I do not know bash scripting. I know some commands like "df -h" to monitor harddisk space but not sure on the other stuffs.

General :: Process Gnome-appearance-properties Causing 100 Percent CPU Usage

Mar 18, 2011

I am running a HP dc5750 dual core computer with a 512MB Nvidia 7200/7300 graphics card my operating system is Ubuntu 10.10. Both my processors are operating at 98-104% cpu usage, it appears that gnome-appearance-properties is the culprit and the only way to return to normal is to end these processes. I have been setting up the desktop cube to my liking and the processor appears to rise up to 100% again. Would getting a 1GB graphics card correct this or is this a bug in maverick meerkat. Any advice would be appreciated. Please keep it simply as I am a Newbie to Linux and find things over-whelming at times. Also would running at 100% on both processors at indefinite periods of time harm my computer.
