There does not appear to be any method from the UI for controlling host inventory mode (Disabled, Manual, Automatic) except on the host itself. Would like to see the following two additions:
1. In the General settings create an option for the "Default" host inventory mode and then use that when new devices are created.
2. Under Actions -> Discovery create an operation to set the host inventory mode so that as we automatically detect certain devices this can be set to the appropriate value.
This will save the need to remember to manually enable this for devices, especially considering we are trying to use discover / actions to pretty much create an "automatic" environment. Thanks!
