Hello @Srijita Mallick (ADMSMB161)

Did you verify if the resource actually exists in the RG?

Any permission restrictions to run the PowerShell script or updating the PowerShell module?

1. Incorrect resource URI: Make sure that the resource URI you are using is correct and points to the Event Hub you want to retrieve metrics for. The resource URI should be in the format /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.EventHub/namespaces/{namespaceName}/eventhubs/{eventHubName}.
2. Insufficient permissions: Make sure that the account you are using to run the Get-AzMetric command has sufficient permissions to access the Event Hub. You may need to grant the account the appropriate permissions using Azure RBAC.
3. Event Hub not found: Make sure that the Event Hub you are trying to retrieve metrics for exists and is in the same region as the Azure PowerShell session you are running the command in.
4. Incorrect metric name: Make sure that the metric name you are using is correct and matches the available metrics for the Event Hub. You can use the Get-AzMetricDefinition command to retrieve a list of available metrics for the Event Hub.

I hope this helps! Let me know if you have any other questions.
