Documentation for oneagent.features (Java MongoDB)

I would like to know what risks and benefits there are for turning on the following OneAgent Java feature. What exactly do I get that’s new when turned on? is there a cost associated with enabling this feature?  I tried looking for documentation on these features but couldn’t find much.

Also, it would be greatly useful if there’s documentation talking about all the one agent features and what they do (if one already exists)

Hi,

I can answer about cost. No extra cost should be added, it is already covered by OneAgent cost.

Best regards
