Hi,
Could you help me understand ovn-controller SB db data retrieve with
monitor-all=false.
In our work we want to catch the moment when no more monitored updates
will be received, i.e. ovn-controller finally catch all data it needs to
make complete open flow.
I made some code investigation and I guess a good candidate is
ovn-controller.c:main()
/* Updating monitor conditions if runtime data or
* logical datapath goups changed. */
if (engine_node_changed(&en_runtime_data)
||
engine_node_changed(&en_sb_logical_dp_group)) {
ovnsb_expected_cond_seqno =
update_sb_monitors(
ovnsb_idl_loop.idl, chassis,
&runtime_data->local_lports,
&runtime_data->lbinding_data.bindings,
&runtime_data->local_datapaths,
sb_monitor_all);
}
I guess if we are not falling into update_sb_monitors() no more changes
comes in during ovsdb_idl_loop_run() called above.
However I am not sure because the main() function is complicated.
Could you please explain how to catch desired condition properly?
Thank you,
Alexander
