12:36 <yog_> Hello everyone how do find the list of probe points available for user process .. I do have debug-info rpm installed but objdump -tT .. isn't listing any symbols related to process other then glibc .. trying with openvsiwtch rpm

13:14 <irker007> systemtap: mcermak systemtap.git:refs/heads/master * release-3.2-219-g9297d41 / systemtap.spec: Make the RPM macro for tapset dir work on older RHELs too. http://tinyurl.com/yb4gj4ev

13:16 <fche> yog_, depends on the type of probe point you're looking for

13:17 <fche> stap -l or -L are the general listing commands

13:17 <fche> stap -l 'process("/path/to/your/binary_or_so").mark("*")' to list any sys/sdt.h markers inside

13:17 <fche> or instead of .mark(...), .function("*") if you have debuginfo for that binary/so installed

13:22 <yog_> fche, mm just tied it.. but still running stap -l 'process("/usr/sbin/ovs-vswitchd").function("*")'|grep pmd .. is empty for rpm based openvswitch with debuginfo rpm installed .. but if i compile the openvswitch manuall.. stap -l does list some functhion with pmf..

13:22 <fche> hm maybe the wrong debuginfo?

13:28 <yog_> fche, debuginfo install .. may be its different between the software version in the function in am looking for .. thanks for the info ;).. was curious if there are any additional steps involved when using debuginfo rpm compared to using process compile from source ..

13:32 <fche> it should work about the same

13:35 <fche> % sudo yum -y install openvswitch openvswitch-debuginfo

13:35 <fche> % stap -l 'process("/usr/sbin/ovs-vswitchd").function("*")'

13:35 <fche> ^^^ gives plenty of output here on fedora27

14:19 <yog_> thanks fche .. yup tried the same on with fedora 28 machine ..as you indicated got lot of output.. was trying on rhel 7.4 machine before.. let me try openvswitch package from diff redhat repo/subscription
