function Get-JobSchedulerMasterCluster { <# .SYNOPSIS Returns Master Cluster information from the JOC Cockpit. .DESCRIPTION Returns any JobScheduler Master Cluster members - including standalone instances - that are connected to JOC Cockpit. .PARAMETER Id Specifies the ID of a JobScheduler Master that was used during installation of the product. If no ID is specified then the first JobScheduler Master registered with JOC Cockpit will be used. .PARAMETER Active This switch specifies that only the active instance of a JobScheduler Master cluster should be returned. Without use of this switch active and passive Master instances in a cluster are returned. .PARAMETER Passive This switch specifies that only the passive instance of a JobScheduler Master cluster should be returned. Without use of this switch active and passive Master instances in a cluster are returned. .OUTPUTS This cmdlet returns an array of Master Cluster member objects. .EXAMPLE $masters = Get-JobSchedulerMasterCluster Returns all Master Clusters members. .EXAMPLE $masters = Get-JobSchedulerMasterCluster -Id some-jobscheduler-id Returns the Master Cluster members with the specified JobScheduler ID ("some-jobscheduler-id"). .EXAMPLE $activeMaster = Get-JobSchedulerMasterCluster -Id some-jobscheduler-id -Active Returns the active Master Cluster member of a cluster with the specified JobScheduler ID ("some-jobscheduler-id"). .LINK about_jobscheduler #> [cmdletbinding()] param ( [Parameter(Mandatory=$False,ValueFromPipeline=$False,ValueFromPipelinebyPropertyName=$True)] [string] $Id, [Parameter(Mandatory=$False,ValueFromPipeline=$False,ValueFromPipelinebyPropertyName=$True)] [switch] $Active, [Parameter(Mandatory=$False,ValueFromPipeline=$False,ValueFromPipelinebyPropertyName=$True)] [switch] $Passive ) Begin { Approve-JobSchedulerCommand $MyInvocation.MyCommand $stopWatch = Start-JobSchedulerStopWatch $returnMasterClusters = @() } Process { Write-Debug ".. $($MyInvocation.MyCommand.Name): parameter Id=$Id" if ( !$Id ) { $Id = $script:jsWebService.JobSchedulerId } $body = New-Object PSObject Add-Member -Membertype NoteProperty -Name 'jobschedulerId' -value $Id -InputObject $body [string] $requestBody = $body | ConvertTo-Json -Depth 100 $response = Invoke-JobSchedulerWebRequest -Path '/jobscheduler/cluster/members' -Body $requestBody if ( $response.StatusCode -eq 200 ) { $returnMasterClusters = ( $response.Content | ConvertFrom-JSON ).masters } else { throw ( $response | Format-List -Force | Out-String ) } if ( ( $Active -and $Passive ) -or ( !$Active -and !$Passive ) ) { $returnMasterClusters } elseif ( $Active ) { $returnMasterClusters | Where-Object { $_.jobschedulerId -eq $Id -and $_.state.severity -eq 0 } } elseif ( $Passive ) { $returnMasterClusters | Where-Object { $_.jobschedulerId -eq $Id -and $_.state.severity -eq 3 } } if ( $returnMasterClusters.count ) { Write-Verbose ".. $($MyInvocation.MyCommand.Name): $($returnMasterClusters.count) Master Clusters found" } else { Write-Verbose ".. $($MyInvocation.MyCommand.Name): no Master Clusters found" } } End { Trace-JobSchedulerStopWatch $MyInvocation.MyCommand.Name $stopWatch } } |
