vSphere Management Assistant repeats Administrator logged in/logged out events

[meimeiriver]

Why, pretty much that: vSphere Management Assistant repeats Administrator logged in/logged out events on ESXi, filling up its 'Events' log. Like so (see below). How can I stop this?! The knowledge base suggested using vilogger, but that seems to have been removed from vMA.

Thanks

You must adjust the loglevel.

See my screenshot:

My bad, I forgot to mention: I don't have vCenter, just the ESXi 6 client.
