if so this was done by virtualmin automatically, as a test add the fpm servers to a system monitor
webmin->tools->system and server status
and activate it (there is no need to display it on the screen yet) and check back a bit later to see if the servers are being monitored and what their status is.
to add php-fpm to system monitors create a bootup action and use the dropdown to select the correct service and rename it, by default the name is bootup action
