perf buildid-cache --add <binary> scans given binary and add the SDT events to probe cache. "sdt_" prefix is appended for all SDT providers to avoid event-name clash with other pre-defined events. It is possible to use the cached SDT events as other cached events, via perf probe --add "sdt_<provider>:<event>=<event>". e.g. ---- # perf buildid-cache --add /lib/libc-2.17.so # perf probe --cache --list | head -n 5 /usr/lib/libc-2.17.so (a6fb821bdf53660eb2c29f778757aef294d3d392): sdt_libc:setjmp=setjmp sdt_libc:longjmp=longjmp sdt_libc:longjmp_target=longjmp_target sdt_libc:memory_heap_new=memory_heap_new # perf probe -x /usr/lib/libc-2.17.so \ -a sdt_libc:memory_heap_new=memory_heap_new Added new event: sdt_libc:memory_heap_new (on memory_heap_new in /usr/lib/libc-2.17.so) You can now use it in all perf tools, such as: perf record -e sdt_libc:memory_heap_new -aR sleep 1 # perf probe -l sdt_libc:memory_heap_new (on new_heap+183 in /usr/lib/libc-2.17.so) ---- Note that SDT event entries in probe-cache file is somewhat different from normal cached events. Normal one starts with "#", but SDTs are starting with "%".
