We are having the same issue(s).
We have an open case:
Case # 585417 - Audit events lacks information
We first noticed ours when we unmanaged some interfaces. I checked the message center to make sure they were unmanaged, yet the only thing that showed up for the day was user logins. (option was set to show all).
The next day our audit trail showed what it needed to for the day, however, still nothing from the day before.
Hope they get this figured out soon...
