discoveryrule.create

Descripció

object discoveryrule.create(array lldRuleIds)

Aquest mètode permet crear noves regles LLD.

Paràmetres

(object/array) Regles de descoberta de baix nivell a crear.

A més de les propietats de l'objecte regla de descoberta de baix nivell estàndard, el mètode admet els paràmetres següents.

Valors de retorn

(object) Retorna un objecte amb els IDs de les regles LLD creades segons la propietat itemids. L'ordre dels IDs retornats correspon a l'ordre de les regles LLD donades.

Exemples

Crear una regla LLD

Crear una regla de descoberta de baix nivell per descobrir els sistemes d'arxius muntats. Els objectes descoberts seran actualitzats cada 30 segons.

Emprant un filtre d'expressió a mida

Crear una regla de descoberta de baix nivell (LLD) amb un filtre que emprarà una expressió a mida per avaluar les condicions. La regla haurà de trobar només els objectes de la macro "{#MACRO1}" que corresponguin a l'expressió regular "regex1" i "regex2", i el valor de la "{#MACRO2}" correspongui a "regex3" o "regex4". Els ID de fórmules "A", "B", "C" i "D" s'escolliran arbitràriament.
