Core Workflows

1. Create Application Insights Component (Workspace-based)

csharp
using Azure.ResourceManager.ApplicationInsights;
using Azure.ResourceManager.ApplicationInsights.Models;

ResourceGroupResource resourceGroup = await client
    .GetDefaultSubscriptionAsync()
    .Result
    .GetResourceGroupAsync("my-resource-group");

ApplicationInsightsComponentCollection components = resourceGroup.GetApplicationInsightsComponents();

// Workspace-based Application Insights (recommended)
ApplicationInsightsComponentData data = new ApplicationInsightsComponentData(
    AzureLocation.EastUS,
    ApplicationInsightsApplicationType.Web)
{
    Kind = "web",
    WorkspaceResourceId = new ResourceIdentifier(
        "/subscriptions/<sub-id>/resourceGroups/<rg>/providers/Microsoft.OperationalInsights/workspaces/<workspace-name>"),
    IngestionMode = IngestionMode.LogAnalytics,
    PublicNetworkAccessForIngestion = PublicNetworkAccessType.Enabled,
    PublicNetworkAccessForQuery = PublicNetworkAccessType.Enabled,
    RetentionInDays = 90,
    SamplingPercentage = 100,
    DisableIPMasking = false,
    ImmediatePurgeDataOn30Days = false,
    Tags =
    {
        { "environment", "production" },
        { "application", "mywebapp" }
    }
};

ArmOperation<ApplicationInsightsComponentResource> operation = await components
    .CreateOrUpdateAsync(WaitUntil.Completed, "my-appinsights", data);

ApplicationInsightsComponentResource component = operation.Value;

Console.WriteLine($"Component created: {component.Data.Name}");
Console.WriteLine($"Instrumentation Key: {component.Data.InstrumentationKey}");
Console.WriteLine($"Connection String: {component.Data.ConnectionString}");

2. Get Connection String and Keys

csharp
ApplicationInsightsComponentResource component = await resourceGroup
    .GetApplicationInsightsComponentAsync("my-appinsights");

// Get connection string for SDK configuration
string connectionString = component.Data.ConnectionString;
string instrumentationKey = component.Data.InstrumentationKey;
string appId = component.Data.AppId;

Console.WriteLine($"Connection String: {connectionString}");
Console.WriteLine($"Instrumentation Key: {instrumentationKey}");
Console.WriteLine($"App ID: {appId}");

3. Create API Key

csharp
ApplicationInsightsComponentResource component = await resourceGroup
    .GetApplicationInsightsComponentAsync("my-appinsights");

ApplicationInsightsComponentApiKeyCollection apiKeys = component.GetApplicationInsightsComponentApiKeys();

// API key for reading telemetry
ApplicationInsightsApiKeyContent keyContent = new ApplicationInsightsApiKeyContent
{
    Name = "ReadTelemetryKey",
    LinkedReadProperties =
    {
        $"/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/microsoft.insights/components/{component.Data.Name}/api",
        $"/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/microsoft.insights/components/{component.Data.Name}/agentconfig"
    }
};

ApplicationInsightsComponentApiKeyResource apiKey = await apiKeys
    .CreateOrUpdateAsync(WaitUntil.Completed, keyContent);

Console.WriteLine($"API Key Name: {apiKey.Data.Name}");
Console.WriteLine($"API Key: {apiKey.Data.ApiKey}"); // Only shown once!

4. Create Web Test (Availability Test)

WorkbookData workbookData = new WorkbookData(AzureLocation.EastUS)
{
    DisplayName = "Application Performance Dashboard",
    Category = "workbook",
    Kind = WorkbookSharedTypeKind.Shared,
    SerializedData = """
    {

    """,
    SourceId = component.Id,
    Tags =
    {
        { "environment", "production" }
    }
};

// Note: Workbook ID should be a new GUID
string workbookId = Guid.NewGuid().ToString();

ArmOperation<WorkbookResource> operation = await workbooks
    .CreateOrUpdateAsync(WaitUntil.Completed, workbookId, workbookData);

WorkbookResource workbook = operation.Value;
Console.WriteLine($"Workbook created: {workbook.Data.DisplayName}");

7. Link Storage Account

csharp
ApplicationInsightsComponentResource component = await resourceGroup
    .GetApplicationInsightsComponentAsync("my-appinsights");

ComponentLinkedStorageAccountCollection linkedStorage = component.GetComponentLinkedStorageAccounts();

ComponentLinkedStorageAccountData storageData = new ComponentLinkedStorageAccountData
{
    LinkedStorageAccount = new ResourceIdentifier(
        "/subscriptions/<sub-id>/resourceGroups/<rg>/providers/Microsoft.Storage/storageAccounts/<storage-account>")
};

ArmOperation<ComponentLinkedStorageAccountResource> operation = await linkedStorage
    .CreateOrUpdateAsync(WaitUntil.Completed, StorageType.ServiceProfiler, storageData);

8. List and Manage Components

csharp
// List all Application Insights components in resource group
await foreach (ApplicationInsightsComponentResource component in 
    resourceGroup.GetApplicationInsightsComponents())
{
    Console.WriteLine($"Component: {component.Data.Name}");
    Console.WriteLine($"  App ID: {component.Data.AppId}");
    Console.WriteLine($"  Type: {component.Data.ApplicationType}");
    Console.WriteLine($"  Ingestion Mode: {component.Data.IngestionMode}");
    Console.WriteLine($"  Retention: {component.Data.RetentionInDays} days");
}

// List web tests
await foreach (WebTestResource webTest in resourceGroup.GetWebTests())
{
    Console.WriteLine($"Web Test: {webTest.Data.WebTestName}");
    Console.WriteLine($"  Enabled: {webTest.Data.IsEnabled}");
    Console.WriteLine($"  Frequency: {webTest.Data.Frequency}s");
}

// List workbooks
await foreach (WorkbookResource workbook in resourceGroup.GetWorkbooks())
{
    Console.WriteLine($"Workbook: {workbook.Data.DisplayName}");
}

9. Update Component

csharp
ApplicationInsightsComponentResource component = await resourceGroup
    .GetApplicationInsightsComponentAsync("my-appinsights");

// Update using full data (PUT operation)
ApplicationInsightsComponentData updateData = component.Data;
updateData.RetentionInDays = 180;
updateData.SamplingPercentage = 50;
updateData.Tags["updated"] = "true";

ArmOperation<ApplicationInsightsComponentResource> operation = await resourceGroup
    .GetApplicationInsightsComponents()
    .CreateOrUpdateAsync(WaitUntil.Completed, "my-appinsights", updateData);

10. Delete Resources

csharp
// Delete Application Insights component
ApplicationInsightsComponentResource component = await resourceGroup
    .GetApplicationInsightsComponentAsync("my-appinsights");
await component.DeleteAsync(WaitUntil.Completed);

// Delete web test
WebTestResource webTest = await resourceGroup.GetWebTestAsync("webtest-homepage");
await webTest.DeleteAsync(WaitUntil.Completed);

Best Practices

  1. Use workspace-based — Workspace-based App Insights is the current standard
  2. Link to Log Analytics — Store data in Log Analytics for better querying
  3. Set appropriate retention — Balance cost vs. data availability
  4. Use sampling — Reduce costs for high-volume applications
  5. Store connection string securely — Use Key Vault or managed identity
  6. Enable multiple test locations — For accurate availability monitoring
  7. Use workbooks — For custom dashboards and analysis
  8. Set up alerts — Based on availability tests and metrics
  9. Tag resources — For cost allocation and organization
  10. Use private endpoints — For secure data ingestion

Error Handling

csharp
using Azure;

try
{
    ArmOperation<ApplicationInsightsComponentResource> operation = await components
        .CreateOrUpdateAsync(WaitUntil.Completed, "my-appinsights", data);
}
catch (RequestFailedException ex) when (ex.Status == 409)
{
    Console.WriteLine("Component already exists");
}
catch (RequestFailedException ex) when (ex.Status == 400)
{
    Console.WriteLine($"Invalid configuration: {ex.Message}");
}
catch (RequestFailedException ex)
{
    Console.WriteLine($"Azure error: {ex.Status} - {ex.Message}");
}

SDK Integration

Use the connection string with Application Insights SDK:

csharp
// Program.cs in ASP.NET Core
builder.Services.AddApplicationInsightsTelemetry(options =>
{
    options.ConnectionString = configuration["ApplicationInsights:ConnectionString"];
});

// Or set via environment variable
// APPLICATIONINSIGHTS_CONNECTION_STRING=InstrumentationKey=...;IngestionEndpoint=...
