Configuration
The Trigger tab contains all the essential trigger attributes.
| Parameter | Description |
|---|---|
| Name | Trigger name. The name may contain macros. $1, $2...$9 macros can be used to refer to the first, second...ninth constant of the expression. Note: $1-$9 macros will resolve correctly if referring to constants in relatively simple, straightforward expressions. For example, the name "Processor load above $1 on {HOST.NAME}" will automatically change to "Processor load above 5 on New host" if the expression is {New host:system.cpu.load[percpu,avg1].last(0)}>5 |
| Expression | Logical expression used for calculating the trigger state. |
| Multiple PROBLEM events generation | By checking this option you can set that an event is generated upon every 'Problem' evaluation of the trigger. |
| Comments | Text field used to provide more information about this trigger. May contain instructions for fixing specific problem, contact detail of responsible staff, etc. |
| URL | If not empty, the URL entered here is available as a link when clicking on the trigger name in Monitoring → Triggers. One macro may be used in the trigger URL field - {TRIGGER.ID}. |
| Severity | Set the required trigger severity by clicking the buttons. |
| Enabled | Unchecking this box will disable the trigger if required. |
The Dependencies tab contains all the dependencies of the trigger.
Click on Add to add a new dependency.
You can also configure a trigger by opening an existing one, pressing the Clone button and then saving under a different name.
