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, 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

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 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

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

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

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

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

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 >

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

Hi , I am getting following error when i try to run xenoprof /usr/local/bin/opcontrol: line 1082: echo: write error: Invalid argument Using 2.6+ OProfile kernel interface. Reading module info. Using log file /var/lib/oprofile/oprofiled.log Daemon started. what is this write error ? Any help is really appreciated. -John _______________________________________________ Xen-users mailing list

I've been trying to get oprofile results for jitted code without success. I built an 3.5.0 llvm with oprofile enabled, and tested it with lli on a small test case. I built the latest oprofile from the git repository. Debugging I can see that lli is registering the listener and making the oprofile calls to the libopagent api to specify the names and address ranges of jit'd routines, and

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

Mi Maurice, A follow up to Andy's comments: MCJIT can find line numbers for ELF files, at least in limited circumstances. I know because I broke the regression test for it while doing some cleanup recently. ;) Looking at lib/ExecutionEngine/OProfileJIT/OProfileJITEventListener.cpp, I see the line: // TODO: support line number info (similar to IntelJITEventListener.cpp) >From a glance at
