function Get-VSAAsset { <# .Synopsis Returns VSA assets. .DESCRIPTION Returns existing VSA assets. Takes either persistent or non-persistent connection information. .PARAMETER VSAConnection Specifies existing non-persistent VSAConnection. .PARAMETER URISuffix Specifies URI suffix if it differs from the default. .PARAMETER AssetID Specifies Asset ID. Returns all assets if not Asset ID specified .PARAMETER Filter Specifies REST API Filter. .PARAMETER Sort Specifies REST API Sorting. .PARAMETER ResolveIDs Return asset types as well as their respective IDs. .PARAMETER Parallel Fetches the remaining pages of a large collection concurrently instead of one after another. Opt-in: without it, behaviour is unchanged. Results are identical either way (same records, merged in $skip order). Only engages once the collection is large enough to be worth it (see -ParallelThreshold). .PARAMETER ThrottleLimit Maximum number of concurrent requests when -Parallel is used (default 8). On shared SaaS you are one tenant among many, so a modest value is a good citizen; the engine also reduces concurrency automatically if the server returns HTTP 429, then recovers. .PARAMETER ParallelThreshold Minimum total record count before -Parallel actually engages. 0 (default) means automatic: two full throttle windows, i.e. 2 * ThrottleLimit * 100 records. Below that the sequential path is used, because it is faster than paying to set up extra connections. .EXAMPLE Get-VSAAsset .EXAMPLE Get-VSAAsset -AssetId '10001' .INPUTS Accepts piped non-persistent VSAConnection .OUTPUTS Array of objects that represent existing VSA assets #> [CmdletBinding(DefaultParameterSetName='All')] param ( [parameter(Mandatory = $false, ValueFromPipelineByPropertyName = $true, ParameterSetName = 'All')] [parameter(Mandatory = $false, ValueFromPipelineByPropertyName = $true, ParameterSetName = 'ById')] [ValidateNotNull()] [VSAConnection] $VSAConnection, [parameter(DontShow, Mandatory=$false, ParameterSetName = 'All')] [parameter(DontShow, Mandatory=$false, ParameterSetName = 'ById')] [ValidateNotNullOrEmpty()] [string] $URISuffix = 'api/v1.0/assetmgmt/assets', [Parameter(Mandatory = $false, ParameterSetName = 'ById')] [ValidateScript({ if( $_ -notmatch "^\d+$" ) { throw "Non-numeric Id" } return $true })] [string] $AssetId, [Parameter(Mandatory = $false, ParameterSetName = 'All')] [ValidateNotNullOrEmpty()] [string] $Filter, [Parameter(Mandatory = $false, ParameterSetName = 'All')] [ValidateNotNullOrEmpty()] [string] $Sort, [Parameter(Mandatory = $false)] [switch] $ResolveIDs, # Opt-in parallel paging for large collections (see Invoke-VSARestMethod).
