### Parametri

`(object)` Parametri, kas nosaka vēlamo izvadi.

Metode atbalsta šādus parametrus.

|Parametrs|[Tips](/manual/api/reference_commentary#data-types)|Apraksts|
|--|--|------|
|ha\_nodeids|ID/array|Atgriezt tikai mezglus ar norādītajiem mezglu ID.|
|filter|object|Atgriezt tikai tos rezultātus, kas precīzi atbilst dotajam filtram.<br><br>Pieņem objektu, kurā atslēgas ir īpašību nosaukumi, bet vērtības ir vai nu viena vērtība, vai vērtību masīvs, ar ko salīdzināt.<br><br>Atbalstītās īpašības: `name`, `address`, `status`.|
|sortfield|string/array|Kārtot rezultātu pēc norādītajām īpašībām.<br><br>Iespējamās vērtības: `name`, `lastaccess`, `status`.|
|countOutput|flag|Šie parametri ir aprakstīti [atsauces komentārā](/manual/api/reference_commentary#common-get-method-parameters).|
|limit|integer|^|
|output|query|^|
|preservekeys|boolean|^|
|sortorder|string/array|^|
