How do I tell how much load a particular process is contributing to each of several available volumes/mounts? Seems that dstat only shows aggregate stats across all processes per disk, and iotop only shows aggregates stats across all disks per process. Thanks.
Currently, I am doing load testing on the Python application which hosted using IIS.
When come to 8-10 ppl hitting the application at the same time, the application getting lag and slower.
However, what I noticed is the python.exe process only running about 300m and it would not up anymore.
I have a little trouble with my server again. My load raises up very much and my cpu is also at 99%. That all happens if i enable one vhost. I get this error messages in my apache error logs:
mod_fcgid: can't apply process slot
All other vhosts works normal. If i disable that one vhost my server runs perfectly with very little load around 0.10.
In some devices the cpu speed is dynamic, being faster when there is more load.
I was wondering if it is possible to set nice level or priority of a process so that it does not influence an increase in cpu speed when it is running flat out.
i.e.
Process is running flat out, but only using spare cpu cycles as low priority.
With linux kernel 2.4.22-1.2199.nptlsmp (I know, it's very old) Sometimes Load average increases to big value (over 7) but my 4 vCPU are in
idle state (5% busy every cpu). My web procedure was gone down so I found out that process (with 4732 process id, see my following output)
was in 'uninterruptible sleep' state (classified as 'D ').
So I am using ssh -X to access a server. I am at a Xubuntu desktop accessing a Ubuntu server that is in the next room. Usually everything works fine, but when the system load gets high, any graphical applications I have freeze and fail to be restarted.
This happens even if the process that is causing the high load has been niced to a low priority with "nice -n 19".
I have an Ubuntu 10.04 VPS and i have noticed a root process that is trying to find some files:
/usr/bin/find /dev /tmp /lib/ etc/ var ( -name tcp.log -o -name .linux-sniff -o -name sniff10 -o -name core_ )
I don't know the origin of this process, and it causes a load average very high.
How To Limit CPU Usage Of A Process With cpulimit (Debian/Ubuntu)
I've been experiencing a strange problem with Plasma locking up. Running system monitor it shows the KDE4 process using 20% CPU time, and Plasma around 10-15%. This seems way too much since on my six year old Laptop the cpu load of both processes is barely noticeable.
