Hosts Discovery

Note

The discovery rules are provided from installation of Plugin Packs (MS Azure, Amazon Web Services, VMware, etc.). To know the complete list, please go to the Plugin Packs catalog.

Discovering new resources is done in two steps:

  1. Start a discovery task

  2. Analyze the result of a discovery task
