Hi Yiming,
Several folks have previously used LTTNG tracepoints with some success.
Also, I find that wallclock profiling can be a good option as it doesn't
require specific tracepoints and can give you a decent "high level" view
of where time is being spent, including time spent contending on locks.
Thanks,
Mark

Hi Cephers,
What is the tracing tool used normally to trace the internal latency for each function
and locks in Ceph?
I’m trying to trace the whole path for each object. Perf counter works for me, but I want
to have a secondary
tool to help me verify my observations.
Please advice.
Thank,
Yiming
