Is lttng enable by default in debian hammer-0.94.5?

[hzwulibin]

Hi, everyone

After install hammer-0.94.5 in debian, i want to trace the librbd by lttng, but after done follow steps, i got nothing:
 2036  mkdir -p traces
 2037  lttng create -o traces librbd
 2038  lttng enable-event -u 'librbd:*'
 2039  lttng add-context -u -t pthread_id
 2040  lttng start
 2041  lttng stop

So, is the lttng enabled in this version on debian?

Thanks!

Hi,

Have you disabled apparmor?

Please check apparmor_status if libvirtd is in enforcing mode then lttng
traces will not be generated.

Thanks,
Shylesh
