ABP vNext + Azure Application Insights：APM 监控与性能诊断最佳实践 🚀

📚 目录

ABP vNext + Azure Application Insights：APM 监控与性能诊断最佳实践 🚀

1️⃣ 集成目标与环境要求

项目	最低版本
.NET SDK	6.0
ABP vNext	7.0
Application Insights	Azure 实例 / Emulator
环境变量注入	`APPLICATIONINSIGHTS_CONNECTION_STRING`

💡 本地调试：

可用 Azure Functions Core Tools --inspect
或使用 Azurite Emulator 模拟

2️⃣ 安装 SDK 与注入服务

dotnet add package Microsoft.ApplicationInsights.AspNetCore

// Program.cs
builder.Services.AddApplicationInsightsTelemetry(options =>
{options.ConnectionString = builder.Configuration["APPLICATIONINSIGHTS_CONNECTION_STRING"];
});
builder.Services.AddSingleton<TelemetryClient>();
builder.Logging.AddApplicationInsights();

3️⃣ 日志与链路追踪整合

🔥 系统流水线示意图

✅ ILogger 原生接入

public class OrderAppService : ApplicationService
{private readonly ILogger<OrderAppService> _logger;public OrderAppService(ILogger<OrderAppService> logger) => _logger = logger;public Task<string> PlaceOrder(){_logger.LogInformation("🛒 开始执行下单逻辑");return Task.FromResult("OK");}
}

✅ 手动埋点（TelemetryClient）

public class OrderManager
{private readonly TelemetryClient _telemetry;public OrderManager(TelemetryClient telemetry) => _telemetry = telemetry;public void TrackLatency(long ms){_telemetry.TrackMetric("OrderService.QueryOrder.LatencyMs", ms);}
}

4️⃣ 多租户与用户上下文注入

public class AbpTelemetryInitializer : ITelemetryInitializer
{private readonly ICurrentUser _currentUser;public AbpTelemetryInitializer(ICurrentUser currentUser) => _currentUser = currentUser;public void Initialize(ITelemetry telemetry){if (_currentUser.IsAuthenticated){telemetry.Context.User.Id = _currentUser.Id?.ToString();telemetry.Context.Properties["TenantId"] = _currentUser.TenantId?.ToString();}}
}// 注册
builder.Services.AddSingleton<ITelemetryInitializer, AbpTelemetryInitializer>();

5️⃣ 后台任务中的链路恢复

using System.Diagnostics;private static readonly ActivitySource BackgroundSource = new("AbpApp.BackgroundJobs");
public async Task ExecuteJobAsync()
{using var activity = BackgroundSource.StartActivity("SyncOrderTask");_telemetry.TrackTrace("🔄 执行后台同步订单", SeverityLevel.Information);// …业务逻辑…
}

⚠️ 推荐使用 ActivitySource 以兼容 OpenTelemetry。

6️⃣ 采样与 TelemetryChannel 调优

🎯 采样 (Sampling)

builder.Services.Configure<TelemetryConfiguration>(config =>
{config.DefaultTelemetrySink.TelemetryProcessorChainBuilder.UseSampling(percentage: 10)  // 10% 采样.Build();
});

⚙ TelemetryChannel 调优

using Microsoft.ApplicationInsights.Channel;
using Microsoft.ApplicationInsights.WindowsServer.Channel;var channel = new ServerTelemetryChannel
{MaxTelemetryBufferCapacity = 500,FlushInterval = TimeSpan.FromSeconds(5)
};
builder.Services.AddSingleton<ITelemetryChannel>(channel);

7️⃣ 自定义指标与告警自动化

// 上报慢 SQL 延迟
_telemetry.TrackMetric("Sql.Query.LatencyMs", elapsedMilliseconds);

// Azure Monitor 告警查询示例
customMetrics
| where name == "Sql.Query.LatencyMs"
| summarize avg(value) by bin(timestamp, 5m)
| where avg_value > 300

8️⃣ CLI 示例：创建告警

az monitor metrics alert create   --name "HighSqlLatency"   --resource-group MyRG   --scopes /subscriptions/<sub>/resourceGroups/MyRG/providers/Microsoft.Insights/components/MyAI   --condition "avg CustomMetrics.Sql.Query.LatencyMs > 300"   --action /subscriptions/<sub>/resourceGroups/MyRG/providers/Microsoft.Web/sites/MyFunc/functions/RestartService

9️⃣ 多环境与安全配置

❌ 禁止在 appsettings.json 明文保存连接串
✅ 使用 环境变量 或 Azure Key Vault
📁 在 appsettings.{Development|Production}.json 中管理差异

{"Logging": {"LogLevel": {"Default": "Information","Microsoft": "Warning"}}
}

🔟 Azure Key Vault 集成示例

using Azure.Identity;builder.Configuration.AddAzureKeyVault(new Uri("https://<YourKeyVault>.vault.azure.net/"),new DefaultAzureCredential());

1️⃣1️⃣ OpenTelemetry 混合方案

builder.Services.AddOpenTelemetryTracing(b =>
{b.AddAspNetCoreInstrumentation().AddHttpClientInstrumentation().AddSource("AbpApp.BackgroundJobs").AddAzureMonitorTraceExporter(o =>{o.ConnectionString = builder.Configuration["APPLICATIONINSIGHTS_CONNECTION_STRING"];});
});
