Host up check endpoint

i would like to set a differen endpoint for the up check fo some hosts.
i tryed to set it the same way i do in the “apply Service”
command_endpoint =
But i had a validation error if i put this in “object Host” or “Template Host”

Idea is to have a group of host that check their uptime by there one, if the check fails by to long time no update i guess this host is down. I know its not the prefered way to do it.

Is there a way to archive this?

Daniel is defined after object host.
using the fqdn worked fine.
