Check space used in azure storage accounts in my subscription

Question

How can I check how much space I used in each of my azure storage accounts in my subscription resource group wise.

I am not able to find a way to check space used in

Answer 1

Here is a .net core script I use to list storage account usage using the average metrics value of the last hour.

using System;
using System.Collections.Generic;
using System.IO;
using System.Threading;
using Microsoft.Azure.Management.CosmosDB.Fluent.Models;
using Microsoft.Azure.Management.Fluent;
using Microsoft.Azure.Management.Monitor;
using Microsoft.Azure.Management.Monitor.Models;
using Microsoft.Rest.Azure.Authentication;

namespace storagelist
{
    class Program
    {
        static async System.Threading.Tasks.Task Main(string[] args)
        {
            // to generate my.azureauth file run the follow command:
            // az ad sp create-for-rbac --sdk-auth > my.azureauth
            var azure = Azure.Authenticate("my.azureauth").WithDefaultSubscription();

            var accounts = azure.StorageAccounts.List();
            // can get values from my.azureauth
            var tenantId = "";
            var clientId = "";
            var clientSecret = "";
            var serviceCreds = await ApplicationTokenProvider.LoginSilentAsync(tenantId, clientId, clientSecret);
            MonitorManagementClient readOnlyClient = new MonitorManagementClient(serviceCreds);

            var oneHour = System.TimeSpan.FromHours(1);
            var startDate = DateTime.Now.AddHours(-oneHour.Hours).ToUniversalTime().ToString("o");
            string endDate = DateTime.Now.ToUniversalTime().ToString("o");
            string timeSpan = startDate + "/" + endDate;

            List fileContents = new List();

            foreach (var storage in accounts)
            {
                var response = await readOnlyClient.Metrics.ListAsync(
                resourceUri: storage.Id,
                timespan: timeSpan,
                interval: oneHour,
                metricnames: "UsedCapacity",

                aggregation: "Average",
                resultType: ResultType.Data,
                cancellationToken: CancellationToken.None);

                foreach (var metric in response.Value)
                {
                    foreach (var series in metric.Timeseries)
                    {
                        foreach (var point in series.Data)
                        {
                            if (point.Average.HasValue)
                            {
                                fileContents.Add($"{storage.Id}, {point.Average.Value}");
                                break;
                            }
                        }
                        break;
                    }
                    break;
                }
            }

            await File.WriteAllLinesAsync("./storage.csv", fileContents);
        }
    }
}
