Need PS script to pull value only of Active status Impacted regions
My Current PS Script:
$varNotifications = gc "C:\Users\pocadmin\Desktop\1.json" | ConvertFrom-Json
if($varnotifications.Impact.ImpactedRegions | Where {$_.Status -eq 'Active'})
{
$varsubscriptionId = $varnotifications.subscriptionid
$varimpactedServices = $varnotifications.Impact.ImpactedService
$varimpactedRegions = $varnotifications.Impact.ImpactedRegions.ImpactedRegion
$varstatus = $varnotifications.Impact.ImpactedRegions.status
}
$varsubscriptionId
$varimpactedServices
$varimpactedRegions
$varstatus
My Output:
xxxx
Azure Active Directory
Multi-Factor Authentication
West US 2
East US
South Central US
Central US
Active
Resolved
Active
Resolved

Answer 1

You shouldn't try to fetch the info in various separate variables, but have the code return an array of objects with values that belong to each other.
Something like this:
$data = Get-Content -Path 'C:\Users\pocadmin\Desktop\1.json' | ConvertFrom-Json
# loop through the data and return only objects where the Status for the ImpactedRegion equals 'Active'
$result = $data.impact | ForEach-Object {
$service = $_.ImpactedService
foreach ($region in ($_.ImpactedRegions | Where-Object {$_.Status -eq 'Active'})) {
[PsCustomObject]#{
Service = $service
Region = $region.ImpactedRegion
Status = $region.Status
}
}
}
# output on screen
$result
# output to CSV file if you like
$result | Export-Csv -Path 'C:\Users\pocadmin\Desktop\1.csv' -NoTypeInformation -UseCulture
On console screen this outputs
Service Region Status
------- ------ ------
Azure Active Directory West US 2 Active
Multi-Factor Authentication South Central US Active
The -UseCulture switch lets PowerShell create a CSV file where the delimiter character is whatever is defined in your systems ListSeparator. By doing this, you can simply double-click the file to open it in Excel on machines that have the same regional settings

Answer 2

Your method only gets an array of the form #(), you need to get the value from it.
$varnotifications.Impact.ImpactedRegions |Where-Object {$_.status -eq "active"} |Select-Object -Expand ImpactedRegion
