[lttng-dev] Discarded events

[Bala Gundeboina]

Hi,

I am Using LTTng in my project , I am recording a kernel session for long duration (eg more than 15minutes) I am enabling all the events for recording but some events discarding after stopping the session, if i run more than 5 minutes only some events are discarding. I have tried to change in the .ltttngrc file also to increase buffer-size.

lttng destroy
Destroying session `my-kernel-session`...
Session `my-kernel-session` destroyed
Warning: 94424667 events were discarded, please refer to the documentation on channel configuration

actually when i am running below command i am getting below warning i am thinking this is the issue because sometimes this warning is not coming that i didn't seen discarded events.  how to overcome this problem can you provide some detailed
lttng-sessiond --daemonize
Warning: Failed to produce a random seed using getrandom(), falling back to pseudo-random device seed generation which will block until its pool is initialized: Failed to get true random data using getre

Thanks & Regards
