function Get-VSAAgentUptime { <# .Synopsis Returns an array of agent uptime records .DESCRIPTION Returns an array of agent uptime records. 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 Since Specifies start date. .PARAMETER Filter Specifies REST API Filter. .PARAMETER Sort Specifies REST API Sorting. .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-VSAAgentUptime -Since "2021-03-04" .EXAMPLE Get-VSAAgentUptime -VSAConnection $connection -Since "2021-03-04" .INPUTS Accepts piped non-persistent VSAConnection .OUTPUTS Array of items that represent system agent views #> [CmdletBinding()] param ( [parameter(Mandatory = $false, ValueFromPipelineByPropertyName = $true)] [ValidateNotNull()] [VSAConnection] $VSAConnection, [parameter(DontShow, Mandatory=$false)] [ValidateNotNullOrEmpty()] [string] $URISuffix = 'api/v1.0/assetmgmt/agents/uptime/{0}', [Parameter(Mandatory = $true, ValueFromPipelineByPropertyName = $true, HelpMessage = 'Date in yyy-mm-dd format')] [ValidateScript({ if( $_ -notmatch "^\d{4}-(0[1-9]|1[0-2])-(0[1-9]|[12][0-9]|3[01])$" ) { throw "Since must be a date in yyyy-MM-dd format (e.g. 2026-07-04)." } return $true })] [string] $Since, [Parameter(Mandatory = $false)] [ValidateNotNullOrEmpty()] [string] $Filter, [Parameter(Mandatory = $false)] [ValidateNotNullOrEmpty()] [string] $Sort, # Opt-in parallel paging for large collections (see Invoke-VSARestMethod).
