.EXAMPLE
Get-vCenterScheduledTask | Select-Object Name,Description,NextRunTime,PrevRunTime,State,Notification
#>
$si = Get-View ServiceInstance
$scheduledTaskManager = Get-View $si.Content.ScheduledTaskManager
$tasks = $scheduledTaskManager.RetrieveEntityScheduledTask($null)
$scheduledtasks = foreach ($task in $tasks){(Get-View $task).info}
$scheduledtasks
}
<#
The above function demonstrates how to "GET" scheduled task information for pretty much EVERYTHING. It doesn't have a filter.
Might be a new version out there, but here are some other samples to filter or even reconfigure a scheduled task.
$vm = get-vm nameofVMIminterestedin
$si = Get-View ServiceInstance
$scheduledTaskManager = Get-View $si.Content.ScheduledTaskManager
$tasks = $scheduledTaskManager.RetrieveObjectScheduleTask($vm.extensiondata.moref) # <-- you could replace $vm.extensiondata.moref w/ any valid object, such as an ESXi host.
$scheduledtasks = foreach ($task in $tasks){(Get-View $task).info}
$scheduledtasks
Example of how you could reconfigure an existing task using the return from the function above.
$vmsch = Get-vCenterScheduledTask | where {$_.Name -match "something completely idiotic so nothing bad happens by running this without knowing what they are doing"}
Foreach ($task in $vmsch)
{
$spec = New-Object VMware.Vim.ScheduledTaskSpec
$spec.name = $task.name
$spec.description = $task.description
$spec.enabled = $true
$spec.scheduler = New-Object VMware.Vim.OnceTaskScheduler
$spec.scheduler.runAt = $task.scheduler.runAt
$spec.action = New-Object VMware.Vim.MethodAction
$spec.action.name = "CreateSnapshot_Task"
$spec.action.argument = New-Object VMware.Vim.MethodActionArgument[] (4)
$spec.action.argument[0] = New-Object VMware.Vim.MethodActionArgument
$spec.action.argument[0].value = ""
$spec.action.argument[1] = New-Object VMware.Vim.MethodActionArgument
$spec.action.argument[1].value = ""
$spec.action.argument[2] = New-Object VMware.Vim.MethodActionArgument
$spec.action.argument[2].value = $true
$spec.action.argument[3] = New-Object VMware.Vim.MethodActionArgument
$spec.action.argument[3].value = $false
$spec.notification = ""
$_this = Get-View -Id $task.ScheduledTask
$_this.ReconfigureScheduledTask($spec)
}
