Hi I am trying to use oprofile with centos 6.0.

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.

On domU domID: 42 Opcontrol --vmlinux=/boot/vmlinux-2..blah 4.) On dom0 Opcontrol --start-daemon --active-domains=41,42 5.) On domU, 41 Opcontrol --reset Opcontrol -...

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 /tmp/myprog and get: warning: [vdso] (tgid:4780 range:0x8d7000-0x8d8000) could not be found. warning: [vdso] (tgid:4784 range:0x...

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.

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 arguments Using 2.6+ OProfile kernel interface. Using log file /var/lib/oprofile/samples/oprofiled.log Daemon started. A...

...rof 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 out that error : counter 0 unavailable. I''ve searched the web, but I couldn''t get the enough info to resolve it. Is there anyone who knows about this issue? Thanks! _______________________________________________ Xe...
