@lazyfrosch Hello Markus. Could you help me here ... :( This Icinga command is great but I need one more functionality here. Are you able to improve a code so there will be a possibility to set a number of services from an exact host?
Right now we are able to set a number of hosts for an exact service.
So in the end, I will be able to create a monitoring service that will be monitoring for example every service on the chosen host and provide an OK status if every service is in OK and Critical status if even one host is in Critical or Unknown.

And yes I know ... but it could be just 5min for you to change a few lines in this Icinga basket.

I'm no longer involved in Icinga for a while now. Please consider this an archive. You can re-use and adapt however you like
