Hi,

Can lttng (LTTng-UST) see perf dynamic probes ?


# perf probe --list probe_libc:malloc_8
  probe_libc:malloc_8  (on __libc_malloc at glibc-2.27/malloc/malloc.c in /lib/x86_64-linux-gnu/libc-2.27.so)

# lttng list -u
UST events:
-------------
None


(Yes, I am doing this as root..., since libc-2.27.so is owned by root)



I know that perf.data and CTF are 2 different formats though.


Thanks
