Hi Sreenath HS,
This step number "Compile a list of classic metrics that you currently use." is refering to create a list of classic metrics because it will be completely retired as you see on the e-mail.
You can get a list of your classic metrics by portal or CLI (https://learn.microsoft.com/en-us/azure/storage/common/storage-analytics-metrics):
From the Azure Portal
- In the Azure portal, select Storage accounts, then the storage account name to open the account dashboard.
- Select Diagnostic settings (classic) in the Monitoring (classic) section of the menu blade.
- Select the type of metrics data for each service you are monitoring,
From the Azure CLI You can use the following command to show metrics settings for a storage account:
az storage metrics show --account-key <your_account_key> --account-name <your_account_name>
After you get this list you can continue with the next step looking for metrics in Azure Monitor provide (https://learn.microsoft.com/en-us/azure/storage/common/storage-metrics-migration)
Let me know if you have any other questions.
Luis
