I will add another log message set to FINE level as follows :
GMS : JoinedAndReady event reported to group XX
This will be the message that you can completely rely on for this event.

The above message will be seen by instances (CORE/SPECTATOR) that have
been started well in advance. It is possible during cluster startup for
some instances to not see this event if they started up a little late.
It will be good if we can also check if the cluster instances receive
this event. And it they don't, can we check if the instance started
late? Not sure how we can do this. Your suggestions are welcome.
Hope this answers your questions.
Thanks
