VCenter Events OpManager 12.2

VCenter Events OpManager 12.2

I am currently using OpManager 12.2 and Im currently taking advantage of the VCenter monitoring.  Daily there is thousands of Events that come in for informational events in for the VCenter Servers.  I see in OpManager Database maintenance I can set how many alarms to keep in the database.  How to do I control how many "Events" to keep in the database.
