You can use the finder methods in the vCenter Server plug-in to query for vCenter Server inventory objects. You can use XPath expressions to define search parameters.
The vCenter Server plug-in includes a set of object finder methods such as getAllDatastores(), getAllResourcePools(), findAllForType(). You can use these methods to access the inventories of the vCenter Server instances that are connected to your Orchestrator server and search for objects by ID, name, or other properties.
For performance reasons, the finder methods do not return any properties for the queried objects, unless you specify a set of properties in the search query.
You can consult an online version of the Scripting API for the vCenter Server plug-in on the Orchestrator documentation home page.
The queries based on XPath expressions might impact the Orchestrator performance because the finder method returns all objects of a given type on the vCenter Server side and the query filters are applied on the vCenter Server plug-in side.
