Question

How to get the usage for an storage account in Microsoft azure using powershell.
I am able to get the storage accounts present in an subscription. But these variables are not exposing any methods by which i can get the usage of an storage account.

Answer 1

I'd say the easiest way (afaik) would be to enable Storage analytics metrics on the storage account and then fetch and aggregate on the logs.
Example (enable metric on Blob)
Set-StorageServicePropertiesForAnalytics -ServiceName "Blob" -StorageAccountName "<Storage Account Name>" -StorageAccountKey "<Storage Account Key>" -MetricsEnabled -MetricsRetentionPolicyDays 7 -MetricsRetentionPolicyEnabled
NB: You have to wait for a while (a day) after enabling the log
Then aggregate (and fetch the usage on the storage account after a day or so):
$logName = "C:\tmp\StorageAccount.log";
Get-StorageAnalyticsMetrics -DataType "Capacity" -ServiceName "Blob" -LocalPath $logName -StorageAccountName "<StoragE account name"> -StorageAccountKey "<Storage account key>"
$results = (Import-Csv $logName | Where-Object { $_.Category -eq "data" } | Select-Object -Last 1 #{Name="AccountName";Expression={"My storage account"}}, Time, "Capacity (bytes)", "Container count", "Object count")
$results
Should give you a data set which is easy to display and aggregate on. You could also iterate multiple storage accounts / containers and split this if you want.
This example only fetches for the blob service. You can also get storage analytics used for other services (table/queue etc); however as specified in the documentation the capacity metric is only available for the blob storage.
For more information on storage account analytics and options see here:

Please note that after enabling the analytics on the Storage account, you'll have to wait before exporting the logs and aggregating on the data.
