Audit when objects put into/removed from maintenance mode

Hi all,

We recently had an outage on some hosts while doing some automated upgrades for vCenter servers, via a script.

Question:

I wanted to find an audit of when the hosts were put into/removed from maintenance mode.

Investigation:

I have checked the User Activity Audit under Admin>History>Audit>User Activity Audit, unfortunately this does not seem to give me the information I am looking for.

I also checked under the Recent Tasks in Admin>History>Recent Tasks, but I see nothing there, and I assume this is only used for the "Actions" adapter.

Would anyone know if there is a way to achieve auditing when an object was put into/removed from maintenance mode?

Thanks!
