如何通过C＃获取Azure Log Analytics工作区的工作区ID

Question

How can I get the Workspace ID of a Log Analytics workspace in Azure via C#?

Answer 1

It seems there is no Log Analytics C# SDK to get the Workspace ID, my workaround is to get the access token vai Microsoft.Azure.Services.AppAuthentication , then call the REST API Workspaces - Get , the customerId in the response is the Workspace ID which you need.

My working sample:

using Microsoft.Azure.Services.AppAuthentication;
using System;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Threading.Tasks;

namespace ConsoleApp6
{
    class Program
    {

        static void Main(string[] args)
        {
            CallWebAPIAsync().Wait();

        }

        static async Task CallWebAPIAsync()
        {
            AzureServiceTokenProvider azureServiceTokenProvider = new AzureServiceTokenProvider();
            string accessToken = azureServiceTokenProvider.GetAccessTokenAsync("https://management.azure.com/").Result;
            using (var client = new HttpClient())
            {
                client.DefaultRequestHeaders.Add("Authorization", "Bearer " + accessToken);
                client.BaseAddress = new Uri("https://management.azure.com/");


                client.DefaultRequestHeaders.Accept.Clear();
                client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
                //GET Method  
                HttpResponseMessage response = await client.GetAsync("subscriptions/<subscription id>/resourcegroups/<resource group name>/providers/Microsoft.OperationalInsights/workspaces/<workspace name>?api-version=2015-11-01-preview");
                if (response.IsSuccessStatusCode)
                {
                    Console.WriteLine(response.Content.ReadAsStringAsync().Result);
                }
                else
                {
                    Console.WriteLine("Internal server Error");
                }
            }
        }
    }
}

I've since found that the OperationalInsightsManagementClient class can be used as well.

var client = new OperationalInsightsManagementClient(GetCredentials()) {SubscriptionId = subscriptionId};
return (await client.Workspaces.ListByResourceGroupWithHttpMessagesAsync(resourceGroupName))
    .Body
    .Select(w => w.CustomerId)
    .FirstOrDefault();
