Hello Xenoprof Users, Can someone please verify the steps to get a oprofile session profile multiple sessions? I am using a file VBD for spawning two guest OS domains on the host. I am doing the following: 1.) On dom0 Opcontrol --xen=/boot/xen-syms-blah 2.) On domU domID: 41 Opcontrol --vmlinux=/boot/vmlinux-2..blah 3.) On domU domID: 42 Opcontrol

Hi I am trying to use oprofile with centos 6.0. I know that the debug-info for the kernel is not available, so I believe I used the correct switches to account for this. here is my script... # reset everything opcontrol --shutdown rm /root/.oprofile/da* opcontrol --separate=kernel --no-vmlinux opcontrol --event=CPU_CLK_UNHALTED:100000 opcontrol --start sleep 5

Hi all, Is anyone using oprofile? I'm getting segfaults from opreport at the moment, and I'm not sure if it is opreport, or just me. In case it is something just plain daft I am doing, here is how it goes: opcontrol --reset opcontrol --setup --no-vmlinux opcontrol --start ... now I run my program, /tmp/myprog ... opcontrol --dump opcontrol --shutdown then I run, opreport -l

Dear experts, to monitor performance of applications on our private clouds I decided to use Xenoprof. For that, I installed patched OProfile 0.9.5 on Dom0 and DomU. Then, I started the daemon on Dom0 opcontrol --start-daemon --active-domains=1 --separate=library --event=LLC_MISSES:90000 and received the following error: /usr/local/bin/opcontrol: line 1171: echo write error: invalid

Hi I am using oprofile 0.9.3 on xen cs 16540 on an Intel system. When I look at the top "hot" functions, I see p2m_change_type being one of the top function in xen-syms. This function is only in the svm (AMD) code and should not appear on an Intel system. I see that this function is not being clled at all when I am running my apps as I have put printk in the functions and they do

Nicholas Thierry-Mieg, Thank you for your reply on Saturday Apr 23,2011. Since then I have been trying to learn how to use oprofile 0.9.4 on Centos Linux 5.5. If I follow the following steps running as root, opcontrol --shutdown opcontrol --callgraph=7 opcontrol --image=/home/frankc/DQTTest5/MatchUpTest/lirh5g_deb/Mary48.exe opcontrol --start

Is it possible to monitor Core Events and Uncore Events simultaneously? Currently, it is not working now in my machine. When I type the command line like this, opcontrol --start-daemon --event=LLC_MISSES:6000::0:1 --event=LLC_REFS:6000::0:1 \ --event=MEM_UNCORE_RETIRED:6000:0x10:0:1 --event=MEM_UNCORE_RETIRED:6000:0x20:0:1 \ --xen=/boot/xen-syms-4.0.1-rc3 --no-vmlinux

Hi all, I am trying to do Xen / Kernel profiling. So I tried passive domain profile with oprofile tool in Dom0 as below. * Environment 1 + i7-2600 CPU + XCP 1.6 Base ISO + CentOS 6.3 Guest (HVM,PV) * Environment 2 + i7-2600 CPU + Xen hypervisor 4.2.1 + Konrad''s passive domain profiling patch applied Dom0 Kernel ( 2.6.32 jeremy branch & 3.2.44 mainline kernel) + CentOS 6.3

So, we just moved to some much faster hardware. intel q6600 CPU, 8Gb unbuffered ECC, ICH7 sata (2x1TB disks) - and we were irritated and puzzled to find that the new setup had really, really slow I/O. The odd thing is that the performance is fine if you just mount the LV directly from the Dom0... but if you xm block-attach it to the Dom0 and then mount it, you get 1/10th the speed. we are

Hello everyone, I''m trying to run Xenoprof (Oprofile 0.9.4) in Gentoo Linux 2.6.21-xen (64 bit) on an AMD 64 system and am facing the following two issues: 1. Xenoprof complains about a write error, but starts and runs anyway. dom0 # opcontrol --start-daemon --active-domains=0 --event=CPU_CLK_UNHALTED:75000::1:1 --vmlinux=/usr/src/linux-2.6.21-xen-dom0/vmlinux

Hi, I want to get the performance data like documents <<Xenoprofoverview&Networking Performance Analysis>> (http://www.xensource.com/files/xs0106_xenoprof.pdf ). But how can I get the modules'' profile in kernel? Now I use command: Opcontrol --no-vmlinux --separate=kernel,cpu --start-daemon ...run benchmark Opcontrol --sutdown Opreport >list The report shows: CPU:

my system configuration xen 3.4.2, oprofile 0.9.5( xenoprof patched ), dom0( jeremy''s pvops kernel 2.6.31.6 - patched dullor''s xenoprof patch ), domU( vanilla kernel 2.6.32 with paravirt enabled ), distribution( ubuntu 9.10 ) In passive mode, xenoprof seems to work well, opreport showed good information. but, in active mode, it seems not to be done correctly. my command is

HI all : I got the message "Using timer interrupt." when trying the command "opcontrol --list-events". then I found infomation "xenoprof: Initialization failed. Intel processor model 44 for P6 class family is not supported“ after "xm dmesg". the TYPE OF CPUS here is Intel(R) Xeon(R) CPU E5620 @ 2.40GHz. So does it really not support this

Hi, I want to use xenoprof to profile the overhead of the hypervisor. I patched the oprofile-0.9.5 using the patch from xenoprof.sourceforge.net Debian GNU/Linux 5.0 (lenny) Xen-4.0.1 + 2.6.32.27 (linux-2.6-pvops.git) Dom0 My platform is Intel(R) Core(TM) i7 CPU 960 @ 3.20GHz My problems are: In Dom0, But hardware performance counters don''t be mounted after initialization

Renato, When I tried running "opcontrol --start" (after previously running "opcontrol --start-daemon") in dom0, I get this error message: /usr/local/bin/opcontrol: line 1639: echo: write error: Operation not permitted and this message in the Xen console: (XEN) xenoprof: operation 9 failed for dom 0 (status : -1) It looks like opcontrol is trying to do this: echo 1 >

I am rebasing Fedora rawhide oprofile package to oprofile-0.9.7. The xenoprof patches on http://xenoprof.sourceforge.net/#download look a bit dated. The newest version is for oprofile-0.9.5. I massaged the patch oprofile-0.9.5-xen.patch to apply to oprofile-.0.9.7. Attached is that updated patch. Does this look reasonable? Is there a desire to get this into upstream oprofile? Or should the

Hi All. I''m trying to use xenoprof in my Xeon machine with PVOPS (3.1.0 kernel) & xen 4.1.1. In the past, I had failed to use the xenoprof in this environment. (1 year ago) While baremetal booting shows the counter object in /dev/oprofile/0 (or 1,2,3) , booting with xen fails to create those objects. Of course, opcontrol command doesn''t work. It only prints
