4 Discovery rules
Overview
The list of low-level discovery rules for a template can be accessed from Data collection → Templates by clicking on Discovery for the respective template.
A list of existing low-level discovery rules is displayed. It is also possible to see all discovery rules independently of the template, or all discovery rules of a specific template group by changing the filter settings.
