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! I am trying to profile my custom 2.6.37 linux kernel with oprofile in centos 5.5, and i have encountered the following problem. (Before everyone starts shouting, I know that custom kernels are not supported by centos team, however I really need to run a modified version, due to a project concerning my MSc thesis. So i hope for your understanding :-) . I have build the kernel

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

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

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 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

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:

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

I'm still running CentOS 5 with Xen. We recently replaced a virtual host system board with an Intel S1400FP4, so the host went from a 4 core Xeon with 32G RAM to a 6 core Xeon with 48G RAM, max 96G. The drives are SSD. I was recently asked to move an InterBase server from Windows 7 to Windows Server. The database is 30G. I'm speculating that if I put the database on a 35G

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 >
