App Gateway, Unable to create health probe with powershell

Question

I'm currently experiencing an issue while attempting to create a health probe using PowerShell. I've already successfully created multiple health probes through the portal.

When I execute the command, I don't receive any error messages. However, upon checking the portal, I cannot find the health probe that I attempted to create using PowerShell. Interestingly, I am able to create a health probe with the same name via the portal.

Any assistance in resolving this issue would be greatly appreciated. Thank you!

I used the command:

$getgw =  Get-AzApplicationGateway -Name Nametest -ResourceGroupName RGtest

# Create the probe object that will check health 
$probeApi = Add-AzApplicationGatewayProbeConfig -ApplicationGateway $getgw -Name $probeNameApi -Protocol Http -Path '/api/test' -Interval 30 -Timeout 120 -UnhealthyThreshold 3

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

I understand that you would like to add a custom probe to your Application gateway.

The command you have shared,

• It only creates a custom Probe.
• But the created probe is neither associated to a Backend HTTP Setting nor the Application Gateway.
• Instead, you must use the below example.

# Load the application gateway resource into a PowerShell variable by using Get-AzApplicationGateway.
$getgw =  Get-AzApplicationGateway -Name appgwtest -ResourceGroupName appgw-rg

# Create the probe object that will check health at http://contoso.com/path/path.htm
$probe = Add-AzApplicationGatewayProbeConfig -ApplicationGateway $getgw -Name probe01 -Protocol Http -HostName 'contoso.com' -Path '/path/custompath.htm' -Interval 30 -Timeout 120 -UnhealthyThreshold 8

# Set the backend HTTP settings to use the new probe
$getgw = Set-AzApplicationGatewayBackendHttpSettings -ApplicationGateway $getgw -Name $getgw.BackendHttpSettingsCollection.name -Port 80 -Protocol Http -CookieBasedAffinity Disabled -Probe $probe -RequestTimeout 120

# Save the application gateway with the configuration changes
Set-AzApplicationGateway -ApplicationGateway $getgw
