appreciate it if you would take some time (~15 min) to give us your feedback:

Hello, I was checking the new REST API documentation but couldn’t find anything about configuring host/services monitoring rules with the API. Is it not there yet? If not how should be the rule creation automated? Thanks!

Yes this part is missing at the moment.
The rule handling is the most complex part of all the configuration and that’s the reason why it takes a little bit longer to finish :wink:

Running this for a few days straight now, haven’t seen any issues. The problems I ran into with b1 and b2 are fixed, lovely. :slightly_smiling_face:

Missing parent/child relationships. How can I set the parent of a host?
I didn’t find the option in the interface.
