Hello everyone In some aspect it might be considered as a continuation of this thread: (link1), yet it is different After we have upgrade from OVN 22.03 to OVN 24.03, we have indeed found increase in performance in 3-4 times And yet still we do observe high CPU load for NorthD process; taking deeper into the logs we have found:
2024-05-07T08:36:46.505Z|18503|poll_loop|INFO|wakeup due to [POLLIN] on fd 15 (10.34.22.66:60716<->10.34.22.66:6642) at lib/stream-fd.c:157 (94% CPU usage) 2024-05-07T08:37:38.857Z|18504|inc_proc_eng|INFO|node: northd, recompute (missing handler for input SB_datapath_binding) took 52313ms 2024-05-07T08:37:48.335Z|18505|inc_proc_eng|INFO|node: lflow, recompute (failed handler for input northd) took 7759ms 2024-05-07T08:37:48.718Z|18506|timeval|WARN|Unreasonably long 62213ms poll interval (56201ms user, 2900ms system) As you can see there is a significant delay in 52 secs Correct me please, if I am in the wrong, but IMU: ‘missing handler for’ – practically means absence of the inc-engine handler from some node (in this sample: SB_datapath_binding) Before plunging into Development it would be great to clarify/adjust with Community’s position * Why there is not handler for this node? * Any particular reason for this or just the peculiarity of our installation highlighted this issue? * Do you think there is a reason in implementing that handler? (SB_datapath_binding) Any ideas are highly appreciated.
