discoveryrule.create

Beschrijving

object discoveryrule.create(object/array lldRules)

Met deze methode kunnen nieuwe LLD-regels worden gemaakt.

Parameters

(object/array) LLD-regels om te maken.

Naast de standaard eigenschappen van LLD-regels accepteert de methode de volgende parameters.

Retourwaarden

(object) Retourneert een object dat de ID's van de gemaakte LLD-regels bevat onder de eigenschap 'itemids'. De volgorde van de geretourneerde ID's komt overeen met de volgorde van de doorgegeven LLD-regels.

Voorbeelden

Maken van een LLD regel

Maak een Zabbix agent LLD regel om mounted bestand systemen te ontdekken. Ontdekte items zullen welke 30 seconden ge-update worden.

Gebruik een filter

Maak een LLD-regel met een set voorwaarden om de resultaten te filteren. De voorwaarden worden gegroepeerd met een logische "en" functie.

Verzoek:

    },
    "id": 1

Een aangepaste expressiefilter gebruiken

Maak een LLD regel met een filter welke een reguliere expressie gebruikt om de voorwaarden te evalueren. De LLR regel mag alleen objecten ontdekken die de "{#MACRO1}" macro gelijk zijn aan "regex1" and "regex2", en de waarde van "{#MACRO2}" matched ofwel "regex3" ofwel "regex4". De formule IDs "A", "B", "C" and "D" zijn willekeurig gekozen.
