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.

Displayed data:

Column	Description
Template	The template discovery rule belongs to.
Name	Name of the rule, displayed as a blue link. Clicking on the rule name opens the low-level discovery rule configuration form. If the discovery rule is inherited from another template, the template name is displayed before the rule name, as a gray link. Clicking on the template link will open the discovery rule list on that template level.
Items	A link to the list of item prototypes is displayed. The number of existing item prototypes is displayed in gray.

Status	Discovery rule status is displayed - Enabled or Disabled. By clicking on the status you can change it - from Enabled to Disabled (and back).

To configure a new low-level discovery rule, click on the Create discovery rule button at the top right corner.

Mass editing options

Buttons below the list offer some mass-editing options:

Enable - change the low-level discovery rule status to Enabled
Disable - change the low-level discovery rule status to Disabled
Delete - delete the low-level discovery rules

To use these options, mark the checkboxes before the respective discovery rules, then click on the required button.

Using filter

You can use the filter to display only the discovery rules you are interested in. For better search performance, data is searched with macros unresolved.

The Filter icon is available at the top right corner. Clicking on it will open a filter where you can specify the desired filtering criteria such as template, discovery rule name, item key, item type, etc.
