Function Get-AvdImageVersionStatus { <# .SYNOPSIS Gets the image version from where the session host is started from. .DESCRIPTION The function will help you getting insights if there are session hosts started from an old version in relation to the Shared Image Gallery .PARAMETER HostpoolName Enter the AVD Hostpool name .PARAMETER ResourceGroupName Enter the AVD Hostpool resourcegroup name .PARAMETER SessionHostName Enter the session host name. .PARAMETER NotLatest This is a switch parameter which let you control the output to show only the sessionhosts which are not started from the latest version. .EXAMPLE Get-AvdImageVersionStatus -HostpoolName avd-hostpool-001 -ResourceGroupName rg-avd-001 #> [CmdletBinding(DefaultParameterSetName = 'Hostpool')] param ( [parameter(Mandatory, ParameterSetName = 'Hostpool')] [parameter(Mandatory, ParameterSetName = 'Sessionhost')] [ValidateNotNullOrEmpty()] [string]$HostpoolName, [parameter(Mandatory, ParameterSetName = 'Hostpool')] [parameter(Mandatory, ParameterSetName = 'Sessionhost')] [ValidateNotNullOrEmpty()] [string]$ResourceGroupName, [parameter(ParameterSetName = 'Sessionhost')] [ValidateNotNullOrEmpty()] [string]$SessionHostName, [parameter()] [switch]$NotLatest ) Begin { Write-Verbose "Start searching" AuthenticationCheck $token = GetAuthToken -resource $Script:AzureApiUrl $apiVersion = "?api-version=2021-07-01" } Process { switch ($PsCmdlet.ParameterSetName) { Sessionhost { $Parameters = @{ HostPoolName = $HostpoolName ResourceGroupName = $ResourceGroupName Name = $SessionHostName } } Default { $Parameters = @{ HostPoolName = $HostpoolName ResourceGroupName = $ResourceGroupName } } } try { $sessionHosts = Get-AvdSessionHostResources @Parameters } catch { Throw "No sessionhosts found, $_" } if ($sessionHosts) { $sessionHosts | Foreach-Object { $isLatestVersion = $false $imageVersionId = $_.vmResources.properties.storageprofile.imagereference.id if ($imageVersionId) { Write-Verbose "Searching for $($_.Name)" # Stripping last part from whole image version id. $filterIdRegex = [Regex]::new("(.*)(?=/versions)") $imageId = $filterIdRegex.Match($imageVersionId).Value $imageNameRegex = [Regex]::new("(?<=images/)(.*)(?=/versions)") $imageName = $imageNameRegex.Match($imageVersionId).Value $galleryNameRegex = [Regex]::new("(?<=galleries/)(.*)(?=/images)") $galleryName = $galleryNameRegex.Match($imageVersionId).Value try { $requestParameters = @{ uri = $Script:AzureApiUrl + $imageId + "/versions" + $apiVersion header = $token method = "GET" } $allVersionsRequest = (Invoke-RestMethod @requestParameters).value | Sort-Object name if ($_.vmResources.properties.storageprofile.imagereference.exactVersion -eq $($allVersionsRequest.name | Select-Object -Last 1)) { $isLatestVersion = $true } else { $isLatestVersion = $false } $imageInfo = @{ currentImageVersion = $_.vmResources.properties.storageprofile.imagereference.exactVersion latestVersion = $allVersionsRequest.name | Select-Object -Last 1 isLatestVersion = $isLatestVersion imageName = $imageName imageId = $imageId imageVersionId = $imageVersionId galleryName = $galleryName } } catch { Write-Warning "Someting went wrong when crawling for info, $_" } } else { $imageInfo = $false Write-Warning "Sessionhost $($_.name) has no image version" } $_ | Add-Member -NotePropertyName imageInfo -NotePropertyValue $imageInfo -Force } } else { Write-Error "No Sessionhosts with resources found in hostpool $HostpoolName" } } End { if ($NotLatest){ $sessionHosts | Where-Object {$_.imageInfo.isLatestVersion -eq $false} } else { $sessionHosts } } } |
