We have a nagios core 4.4.10. We do use the parent child relations. So in Windows environment do have hyper-v hosts. The hosts running multiple VMs which are also monitored.
We do use (or trying) scheduled downtime. For that I created a time period, with an exclude, so for example at every Monday from 4 am to 6 am, some host are scheduled for downtime.
I only added the physical hyper-v hosts to this time period. My problem is that if the hyper-v host is gets back online and the VMs are still booting or in down state, we are getting notifications. How can I avoid this? Is this an expected behaviour? I know I can add all the VMs to the scheduled downtime settings, but is much more work.
I tried manually to set up a new downtime window, and checked the behaviour. I do not know if I am missing some information, or is this how nagios should work.
Thanks Peter
