Accepta una matriu on les claus són noms de propietat i els valors són un valor únic o una matriu de valors per comparar.< br> Admet filtres addicionals: host - Nom tècnic de l'equip al qual pertany l'element. |
| limitSelects | integer | Limita el nombre de registres retornats per les subconsultes. S'aplica a les subconsultes següents: selectGraphs - els resultats s'ordenaran per name;< br>selectTriggers - resultats s'ordenarà per description. |
| sortfield | string/array | Ordena el resultat per les propietats donades. Els valors possibles són: itemid, name, key_, delay, history, trends , type i status. |
| countOutput | boolean | Aquests paràmetres es descriuen als comentaris de referència. |
| editable | boolean | |
| excludeSearch | boolean | |
| limit | integer | |
| output | query | |
| preservekeys | boolean | |
| search | object | |
