I think the perfmon patches are supposed to work only up to kernel version 2.6.30. Your kernel supports the perf_events interface, and the perf tool. Are you familiar with these? You can find some info in Vince Weaver's web pages: http://web.eecs.utk.edu/~vweaver1/projects/perf-events/ There are instructions in there about how to install it for Ubuntu/debian. There are also man pages in the kernel source tree under tools/perf/Documentation - Corey > > Ulises > > $ pfmon --verbose --us-counter-format --no-cmd-output -e instructions_retired > -- gcc hello.c -o hello -O2 -static > > measuring at user privilege level ONLY > 1 event set(s) defined > long sampling periods(val/mask/seed): 0/0x0/0 > short sampling periods(val/mask/seed): 0/0x0/0 > unavailable_pmcs=0xfffcfffc > unavailable_pmds=0xfff8fffc > [FIXED_CTRL(pmc16)=0xa pmi0=1 en0=0x2 pmi1=1 en1=0x0 pmi2=1 en2=0x0] > INSTRUCTIONS_RETIRED > [FIXED_CTR0(pmd16)] > pmd setup for event set0: > [pmd16 set=0 ival=0x0 long_rate=0x0 short_rate=0x0 mask=0x0 seed=0 > randomize=n] > exec-pattern=* > [15634] started task: gcc hello.c -o hello -O2 -static > follow_exec=n follow_vfork=n follow_fork=n follow_pthread=n > [15634] 32-bit binary > [15634] monitoring /usr/bin/gcc-4.4... > [15634] results are on terminal > [15634] activating monitoring > measurements started at Thu May 5 19:12:06 2011 > > [15634] task exited with error code 0 > 1,708,975 INSTRUCTIONS_RETIRED > [15634] detached > sdesc chain to process: > created tasks : 0 > maximum tasks : 1 > maximum active tasks : 1 > measurements completed at Thu May 5 19:12:06 2011 > > > $ pfmon --verbose --follow-all --us-counter-format --no-cmd-output -e > instructions_retired -- gcc hello.c -o hello -O2 -static > > measuring at user privilege level ONLY > 1 event set(s) defined > long sampling periods(val/mask/seed): 0/0x0/0 > short sampling periods(val/mask/seed): 0/0x0/0 > unavailable_pmcs=0xfffcfffc > unavailable_pmds=0xfff8fffc > [FIXED_CTRL(pmc16)=0xa pmi0=1 en0=0x2 pmi1=1 en1=0x0 pmi2=1 en2=0x0] > INSTRUCTIONS_RETIRED > [FIXED_CTR0(pmd16)] > pmd setup for event set0: > [pmd16 set=0 ival=0x0 long_rate=0x0 short_rate=0x0 mask=0x0 seed=0 > randomize=n] > exec-pattern=* > [15566] started task: gcc hello.c -o hello -O2 -static > follow_exec=y follow_vfork=y follow_fork=y follow_pthread=y > [15566] 32-bit binary > [15566] monitoring /usr/bin/gcc-4.4... > [15566] results are on terminal > [15566] activating monitoring > measurements started at Thu May 5 19:10:37 2011 > > [15567] out-of-order creation, stopped > [15566] vforked [15567] > [15567] monitoring /usr/bin/gcc-4.4... > [15567] results are on terminal > [15567] activating monitoring > [15567] resuming > [15567] 32-bit binary > [15567] exec /usr/lib/gcc/i486-linux-gnu/4.4/cc1... > [15567] monitoring /usr/lib/gcc/i486-linux-gnu/4.4/cc1... > [15567] task exited with error code 0 > 52,376,899 INSTRUCTIONS_RETIRED > /usr/lib/gcc/i486-linux-gnu/4.4/cc1 (15567,15567,15566) > [15567] detached > [15568] out-of-order creation, stopped > [15566] vforked [15568] > [15568] monitoring /usr/bin/gcc-4.4... > [15568] results are on terminal > [15568] activating monitoring > [15568] resuming > [15568] 32-bit binary > [15568] exec /usr/bin/as... > [15568] monitoring /usr/bin/as... > [15568] task exited with error code 0 > 2,153,624 INSTRUCTIONS_RETIRED /usr/bin/as > (15568,15568,15566) > [15568] detached > [15569] out-of-order creation, stopped > [15566] vforked [15569] > [15569] monitoring /usr/bin/gcc-4.4... > [15569] results are on terminal > [15569] activating monitoring > [15569] resuming > [15569] 32-bit binary > [15569] exec /usr/lib/gcc/i486-linux-gnu/4.4/collect2... > [15569] monitoring /usr/lib/gcc/i486-linux-gnu/4.4/collect2... > [15570] out-of-order creation, stopped > [15569] vforked [15570] > [15570] monitoring /usr/lib/gcc/i486-linux-gnu/4.4/collect2... > [15570] results are on terminal > [15570] activating monitoring > [15570] resuming > [15570] 32-bit binary > [15570] exec /usr/bin/ld... > [15570] monitoring /usr/bin/ld... > [15570] task exited with error code 0 > 106,632,326 INSTRUCTIONS_RETIRED /usr/bin/ld > (15570,15570,15569) > [15570] detached > [15569] task exited with error code 0 > 958,373 INSTRUCTIONS_RETIRED > /usr/lib/gcc/i486-linux-gnu/4.4/collect2 (15569,15569,15566) > [15569] detached > [15566] task exited with error code 0 > 1,708,975 INSTRUCTIONS_RETIRED /usr/bin/gcc-4.4 > (15566,15566,15565) > [15566] detached > sdesc chain to process: > created tasks : 0 > maximum tasks : 3 > maximum active tasks : 3 > measurements completed at Thu May 5 19:10:37 2011 > > > > ------------------------------------------------------------------------------ > WhatsUp Gold - Download Free Network Management Software > The most intuitive, comprehensive, and cost-effective network > management toolset available today.
