Notes on low-level discovery

Application discovery

Application prototypes support LLD macros.

One application prototype can be used by several item prototypes of the same discovery rule.

Like other discovered entities applications follow the lifetime defined in discovery rule ('keep lost resources period' setting) - they are removed after not being discovered for the specified number of days.

If an application is not discovered anymore all discovered items are automatically removed from it, even if the application itself is not yet removed because of the 'lost resources period' setting.

Application prototypes defined by one discovery rule can't discover the same application. In this situation only the first prototype discovery will succeed, the rest will report appropriate LLD error. Only application prototypes defined in different discovery rules can result in discovering the same application.
