4 Discovery rules

Overview

The list of low-level discovery rules for a template can be accessed from Configuration → 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 host 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.
Triggers	A link to the list of trigger prototypes is displayed. The number of existing trigger prototypes is displayed in gray.
Graphs	A link to the list of graph prototypes displayed. The number of existing graph prototypes is displayed in gray.
Hosts	A link to the list of host prototypes displayed. The number of existing host prototypes is displayed in gray.
Key	The item key used for discovery is displayed.
Interval	The frequency of performing discovery is displayed.
Type	The item type used for discovery is displayed (Zabbix agent, SNMP agent, etc).
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.

Templates	Filter by one or more templates.
Name	Filter by discovery rule name.
Key	Filter by discovery item key.
Type	Filter by discovery item type.
Update interval	Filter by update interval. Not available for Zabbix trapper and dependent items.
