Each user can have two values of type: movement and check-in. There are some users that only have movement and never check-in.
I've tried grouping these type values and then filtering those users that only have one value, but can't quite figure it out!
Try something like this
index=dfw host=MC1 | stats values(type) as Action by id | where mvcount(Action)=1 AND Action="movement" | sort Action
