Overview
The trigger list for a template can be accessed from Configuration → Templates and then clicking on Triggers for the respective template.
The trigger list for a host can be accessed from Configuration → Hosts and then clicking on Triggers for the respective host.
A list of existing triggers is displayed. By default, only the enabled triggers are displayed. To display disabled triggers as well, use the Show disabled triggers link to the right in the Triggers bar.
Displayed data:
| Column | Description |
|---|---|
| Severity | Severity of the trigger is displayed by both name and cell background colour. |
| Name | Name of the trigger, mostly displayed as a blue link except for triggers created from trigger prototypes. Clicking on the trigger name link opens the trigger configuration form. If the host trigger belongs to a template, the template name is displayed before the trigger name, as a grey link. Clicking on the template link will open the trigger list on the template level. If the trigger has been created from a trigger prototype, its name is preceded by the low level discovery rule name, in khaki. Clicking on the discovery rule name will open the trigger prototype list. |
| Expression | Trigger expression is displayed. The host-item part of the expression is displayed as a link, leading to the item configuration form. |
| Status | Trigger status is displayed - Enabled, Disabled or Unknown. By clicking on the status you can change it - from Enabled to Disabled (and back); from Unknown to Disabled (and back). |
| Error | A green checkbox icon is displayed if there are no errors. A red icon with a cross is displayed if there are errors. Move the mouse over the icon and you will see a tooltip with the error description. No icon is displayed if the rule is disabled. |
To configure a new trigger, click on the Create trigger button in the top right-hand corner.
