Hi Steven,
GDB shows that the vlib_process_get_events function always return ~0, except
one time at start and lacp_schedule_periodic_timer is never runs after that.
It's looks the same on both sides.
I have added some debug info. Please look at the log:

Many thanks for your help. I will think about it ) I think, I'll create right

Unfortunatelly, session_lookup_connection_wt4/6 is not work for me. I thought
that it was not intended for transit connections. At now VPP crashes when I
call it. Maybe it

Hi Everyone!
I am trying to parse binary ELOG file, but have no success.
Is there someone who know something about ELOG file format?
At now I'm trying to get the unix timestamp of the each event.

Thanks Florin! Thanks Damjan!
I know about these tools, but both of them uses elog_read_file function, which
is described in elog.h
This function consist of 3 other functions: unserialize_open_clib_file,
unserialize and unserialize_close.
If I right, the elog file parsing should be in unserializ
Correction: I've found all of unserialize_* functions. Trying to understand..

Hi Florin,
Thank you very much! It works now.
1) Why you use such big memory size value (256 << 20) in
clib_mem_init_thread_safe ?
Maybe we must to calculate the required size?
sizeof(elog_main_t) + elog_file_size ?
2) I've calculate start time of a log from init_time:
elog_main_t *em = &elog_m

In my opinion, the event-logger cli command has uncomfortable format of

Dave,
Thanks for your explanation!
In my opinion, it depends on what the "is_mp_safe" flag actually means. If all
the functions are actually thread-safe and these barrier synchronization calls
are required mainly for debugging, then I suggest the following:
#if CLIB_DEBUG > 0
if (!c->is_mp_safe
Hello Everyone,
I have a small set of the fixes for VPP, but unfortunatelly right now, I have
no time for pushing the code with git review.
I hope that these fixes are very useful for the project and I would be very
happy if someone could do it instead of me.
In any case I hope that these fixes
