Just checked and we are running the same version of Orbit (which is also the latest pushed). It is an older version of the extension... we need to update that dependency to pull in those new tables. You're saying that

select * from unified_log where predicate='processImagePath contains "mdmclient"';

does return results?

Oh, i'm sorry, I misread this. Yes, this sorta returns results - I have to CTRL+C after a bit
