Report on Client that have run no actions

HI

We have an issue with some client enrol\register.
Although they appear in the console as registered and looking at logs on the client they are talking to a relay they do not run any actions.
When you look in the console they are registered but the action history is empty as they have run no actions.

Is there a way to generate a report that lists the machines that have run no actions?

This would allow us to identify the machine we need to look at and try to work out the root cause.

Regards
