We suddenly had a ton of pingable devices be discovered, how can we find where they came from and prevent it from happening again?
These devices were discovered due to the Quick Discovery option being used instead of a manually created discover profile.
Release : 3.7
Component : IM Reporting / Admin / Configuration
As the Quick Discovery option generates a fresh discover profile that does not adhere to the Template Discover Profile if you had one set, the way to get this to not happen is a process change. You need to omit using the Quick Discovery capability and generate a new discover profile, this profile will allow you to not discover pingables.
