Hi ,
Thank you, events_discarded may be of some help for us. Our main requirement
is to find the number of discarded events per session
Ex: We use lttng_create_session() to create an session and then enabled certain
events using lttng_enable_event(). The events come from different
processes.
Now, as a whole, can we get the number of discarded events for the whole
session??
Thanks & Regards,K.V.Ranganadh.

There is no way to know from the application while the trace is being
captured. I wonder what form such a mechanism would take to,
basically, query the tracer/ring buffer for the events_discarded
counter... This would arguably be of little use in per-uid mode (since
a user's apps share the same buffer), but I could see this being
useful in per-pid mode.
Any ideas?
