Hi
I want to try systemtap and started its installation as given in
http://sourceware.org/systemtap/wiki/SystemtapOnFedora.
Then I tried -
Code:
# stap -ve 'probe begin { log("hello world") exit () }'
It worked fine. But if i try the following command I am getting errors ..
Code:
# stap -c df -e 'probe syscall.* { if (target()==pid()) log(name." ".argstr) }'
semantic error: libdwfl failure (missing i686 kernel/module debuginfo under '/lib/modules/2.6.25.10-86.fc9.i686/build'): No such file or directory while resolving probe point kernel.function("sys_access")
semantic error: libdwfl failure (missing i686 kernel/module debuginfo under '/lib/modules/2.6.25.10-86.fc9.i686/build'): No such file or directory while resolving probe point kernel.function("sys_adjtimex")
.
.
Even tried a script which is showing following errors
Code:
# stap strace-open.stp
semantic error: no match while resolving probe point syscall.open
Pass 2: analysis failed. Try again with another '--vp 01' option.
Missing separate debuginfos, use: debuginfo-install kernel-2.6.25.10-86.fc9.i686
I think there is some problem with installation ...
Is there any guide on installation via yum or so ... ??
I even tried
Code:
# debuginfo-install kernel-2.6.25.10-86.fc9.i686
Loaded plugins: refresh-packagekit
