Osquery uses basic SQL commands to leverage a relational data-model to describe a device.

Hello, would it be possible for osquery agent to somehow ask fleet to scan him cause he has a new important data?

Hey <@U047JHABBGT>! What kind of new important data are we talking about?

Hello. e.g. New content for the tables that monitor critical events.

Hi <@U047JHABBGT>!

The same way you can trigger a "refetch" of a host in the UI, you can refetch via the API: `POST /api/latest/fleet/hosts/{host_id}/refetch`

"Refetching" a host which will make it run all the host details, software, policies and additional queries they are configured to run periodically.

Maybe you can use such API to trigger a refetch of a host when your system detects a need.
