Enable/Disable AppInsights Availability Tests with Powershell Azure ARM

Question

Simple question, trying to use Powershell Azure ARM to Disable/Enable my Application Insights Availability Tests. We have scheduled reboots of our servers, and I want to black out those times so we don't record errors.

I tried the following

$alert = Get-AzureRmAlertRule -ResourceGroupName $resourceGroup `
        | Where-Object {$_.Name -like '*isalive*'} `
        | Where-Object {$_.Name -like "*$vmName*"} 


Add-AzureRmWebtestAlertRule -Name $alert.Name `
    -Location $alert.Location `
    -ResourceGroupName $resourceGroup `
    -WindowSize $alert.Condition.WindowSize `
    -MetricName  $alert.Condition.DataSource.MetricName `
    -TargetResourceUri $alert.Id `
    -FailedLocationCount $alert.Condition.FailedLocationCount `
    -DisableRule `
    -Verbose

https://learn.microsoft.com/en-us/powershell/module/azurerm.insights/add-azurermwebtestalertrule?view=azurermps-6.8.1

But I get Back

WARNING: 3:34:18 PM - The namespace for all the model classes will change from Microsoft.Azure.Management.Monitor.Management.Models to Microsoft.Azure.Management.Monitor.Models in future releases.

WARNING: 3:34:18 PM - The namespace for output classes will be uniform for all classes in future releases to make it independent of modifications in the model classes.

And if I try Resolve-AzureRmError -Last I get

HistoryId: 80
