Oh, I see what that is. This appears to be a neglected piece of code. ES
has this but Kibana does not, for instance. The metainfo.xml allows you to add
"commandScript" items that are listed in the service drop-down menu. But this
is distinct from the status check which provides the green checkbox vs red
exclamation appearing next to a service name in the Ambari services list.
This is ES

This is Kibana

I'd like to treat this as distinct from the status check if that seems
reasonable to you. I have to admit, I didn't even know the service check piece
existed until now.
