Is it best practice to use useACK in outputs.conf

[ekenne06]

I have inherited a SPlunk environment and one thing i've noticed is that one all of our heavy forwarders are using useACK.  Is this best practice? we are seeing duplicate events due to this, and I wanted to see if I should work on tailoring the config for indexer acknowledgement, or if I should just disable it and move on.

It depends on your goals.  To prevent data loss, useACK is recommended.  Acknowledgement increases the chances of data duplication, however, so that needs to be accounted for in searches.  Choose to use useACK based on which scenario is least painful to you.
