How do I change a Cribl worker's Host name?

In the Workers tab, the second column, “Host”, shows the Cribl worker node name. Currently, I have some hosts with a hostname, and other hosts with hostname + domain name.
How can I change the hostname to be consistent here?

To change the name of the worker in the Leader UI you can edit the /etc/hostname and restart the machine.
This will edit the host name of the Machine and require a restart of the Operating system.
