Unable to create MetricAlert using Add-AzMetricAlertRuleV2

[kiruthigavasu]

I am trying to create a MetricAlert using the following script

Set-AzContext -Subscription "f0bXXXXXXX"
$action = Get-AzActionGroup -ResourceGroupName gze-actgrp-pd-rgp-001 -Name UWDevOps_PD
$actionID = New-AzActionGroup -ActionGroupId $action.id

#Get-AzMetricDefinition -ResourceId "/subscriptions/9ca95ff2-f1fd-447d-9130-9081d2ba12be/resourcegroups/gze-pdi203-pd1-rgp-001/providers/Microsoft.ContainerService/managedClusters/gze-pdi203-pd1-aks-isostr-001"

#set alert dim to pick the right options
$dim = New-AzMetricAlertRuleV2DimensionSelection -DimensionName "Name of the nodepool" -ValuesToInclude "pdi203pd101"

$severity = 1

$RGObject = "gze-pdi203-pd1-rgp-001"

$ResourceId = "/subscriptions/9caXXXXXXX/resourcegroups/gze-pdi203-pd1-rgp-001/providers/Microsoft.ContainerService/managedClusters/gze-pdi203-pd1-aks-isostr-001"

#set alert criteria and counter % Processor Time
$criteria = New-AzMetricAlertRuleV2Criteria -MetricName "podReadyPercentage" -DimensionSelection $dim
-TimeAggregation average -Operator LessThan
-Threshold 50

Set-AzContext -Subscription "921XXXX" # subID of the GZ-NP-IT-203-AKSISDUWSYS

Add-AzMetricAlertRuleV2 -Name "UWS-AKS203-ISOSTR-DV1-[Sev0-Critical]-Pods-Ready-Percentage less than 50-V2-CT" -ResourceGroupName $RGObject
-WindowSize 01:00:00 -Frequency 01:00:00
-TargetResourceId $ResourceId -Condition $criteria
-ActionGroup $actionID `
-Severity $severity

But then it fails here $actionID = New-AzActionGroup -ActionGroupId $action.id
saying that New-AzActionGroup is not recognized.
I have Az.Monitor 4.5 ver, AZ module ver 10.0.0 and windows PS ver 5.1
On reading some more blogs, it was made clear that New-AzActionGroup was not available in Az.MOnitor 4.5 and was only until ver 3.1.0. I tried to force install 3.1.0 using
Install-Module -Name Az.Monitor -RequiredVersion 3.0.1 -Force
but that did not install 3.0.1 either..

If anyone had found a workaround over this, kindly help me,. I am stuck and unable to move further and any help from the community is highly appreciated.

I fixed this issue by uninstalling Az.Monitor and installing Az.Monitor 3.1.0 and went past that error.
But I get another error "Couldn't find a metric named podReadyPercentage."

Add-AzMetricAlertRuleV2 : Exception type: ErrorResponseException, Message: Couldn't find a metric named podReadyPercentage. Make sure the name is correct. Activity ID:

But as per MS doc that is the name listed https://learn.microsoft.com/en-us/azure/azure-monitor/containers/container-insights-custom-metrics?tabs=portal

So not sure what else I am missing here. Any help anyone?

I am unable to create alerts for any of the preview ones.. I am using Az.Monitor ver 3.1.0 and Az ver 10.0.1, if that may help..

I needed Az.Monitor ver 3.1.0 for New-AzActionGroup cmdlet to work.
