You create a rule “Windows Service Discovery”. You can use a filter for examp,e olnly discover running services with automatic start settings:
Or you leave the enbtries blank to discover every services.
Define the wanted hosts via the folder or with explicit names or whatsever… I tested with one single host AS017 in my screenshot.
(I use only manually defined services so far.)
After you saved the rule open the host in WATO and run a FULL SCAN for new services:
To define the status OK/WARN/CRIT you have to use another rule. Default setting lokks like service running = OK, service stopped = CRIT.
I don’t know if this is also possible for processes.
I use a few single rules for one single process to check if the pricess is running. (Manual Checks → State and count of processes)
Another interesting thing four you could also be the agent plugin for windows tasks! (but there are a lot more interesting plugins 
)
