Here you can include or exclude hosts in the workflow. The purpose of this is to create segregated farming environments that lets you design special workflow for special members of the farm.
Host
The host to add to the list. Default is the current host. You can insert any host on the list. The hosts will not be validated so you must write the correct name for the host.
Add host
Add the host to the list.
Add group
Add the hosts group to the list.
Remove
Removes selected host(s) from the list.
Note: Groups in the list will be identified with * asterisks *.
List includes hosts/groups
Option tells the workflow that the hosts on the list will take part of the workflow jobs.
List excludes hosts/groups
Option tells the workflow that the hosts will NOT take part of the workflow jobs.
Note: An empty list makes all the host participate in the workflow jobs regardless of the two latter options.
