Hi,
In a distributed environment, what will happen if you bring down the console 
and the event processor for maintenance(lets say for 8 hours), will the remote collectors store the events until the connection is back and than push them? or will i lose the events for good?

Thanks,
Itzik

Hi arjun,
Thanks for the reply.
I have seen this post.
The question is - what will happen if i do not configutre scheduling? will the events just get droped?

Then i believe its a 5GB queue limit which will apply

The 5 GB limit is for the license filter spillover queue - this comes into play if the Event Collector is receiving more raw events than it is licensed for.

There is a separate on-disk queue used when the EC cannot reach the downstream EP, as in the case Itzik described. That queue will basically fill until there is no disk space left - it actually stops at 93% or 95% or something like that, but as opposed to the license spillover it is effectively unbounded. When the EP comes back up, all the events will be sent at that time.

Cheers
Colin

Thanks for the update Colin. This type of information is very hard to find on IBM documentation :)
