依赖安装与多环境配置 🧰

dotnet add package Sentry.AspNetCore
dotnet add package Serilog.Sinks.Elasticsearch
dotnet add package Serilog.Enrichers.Environment
dotnet add package Serilog.Enrichers.Thread
dotnet add package Serilog.Enrichers.CorrelationId
dotnet add package Volo.Abp.Serilog
dotnet add package AspNetCore.HealthChecks.UI

// Program.cs - 配置读取顺序
var builder = WebApplication.CreateBuilder(args);builder.Configuration.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true).AddJsonFile($"appsettings.{builder.Environment.EnvironmentName}.json", optional: true).AddEnvironmentVariables();

---

安全日志配置 🔐

appsettings.Development.json

{"Sentry": {"Dsn": "${SENTRY_DSN}","TracesSampleRate": 1.0,"Debug": true},"Serilog": {"MinimumLevel": { "Default": "Debug" },"WriteTo": [ { "Name": "Console" } ]}
}

appsettings.Production.json

{"Sentry": {"Dsn": "${SENTRY_DSN}","TracesSampleRate": 0.2,"SendDefaultPii": true,"AttachStacktrace": true,"Debug": false,"DiagnosticsLevel": "Error"},"Serilog": {"Using": [ "Serilog.Sinks.Elasticsearch" ],"MinimumLevel": {"Default": "Information","Override": { "Microsoft": "Warning" }},"WriteTo": [{"Name": "Elasticsearch","Args": {"NodeUris": "http://elasticsearch:9200","AutoRegisterTemplate": true,"AutoRegisterTemplateVersion": "ESv7","IndexFormat": "abp-logs-{0:yyyy.MM.dd}"}}],"Enrich": [ "FromLogContext", "WithMachineName", "WithThreadId" ]}
}

秘钥注入：
.NET 默认支持用环境变量 SENTRY__DSN（双下划线表示冒号）覆盖 Sentry:Dsn。

export SENTRY__DSN=https://xxxx@sentry.io/project

Elasticsearch 索引模板 📑

curl -X PUT "localhost:9200/_template/abp-logs-template" -H "Content-Type: application/json" -d '
{"index_patterns": ["abp-logs-*"],"settings": { "number_of_shards": 3 },"mappings": {"properties": {"TenantId":  { "type": "keyword" },"Module":    { "type": "keyword" },"Timestamp": { "type": "date" },"Level":     { "type": "keyword" },"Message":   { "type": "text" }}}
}'

程序启动与 DI 注册 ⚙️

var builder = WebApplication.CreateBuilder(args);// 1. CorrelationId 中间件
builder.Services.AddCorrelationId();// 2. Sentry SDK
builder.Services.AddSentry(o =>
{o.Dsn = builder.Configuration["Sentry:Dsn"];o.TracesSampleRate = 0.2;o.AttachStacktrace = true;o.Debug = false;
});// 3. Serilog 注册
builder.Host.UseSerilog((ctx, lc) =>
{lc.ReadFrom.Configuration(ctx.Configuration).Enrich.WithCorrelationId().Enrich.WithMachineName().Enrich.WithEnvironmentUserName().Enrich.WithProcessId().Enrich.With<TenantLogEnricher>();
});// 4. 全局异常订阅
builder.Services.AddSingleton<IExceptionSubscriber, GlobalExceptionSubscriber>();// 5. HealthChecks + UI
builder.Services.AddHealthChecks().AddSqlServer(builder.Configuration.GetConnectionString("Default"), name: "SQL").AddRedis(builder.Configuration["Redis:Configuration"], name: "Redis").AddHealthChecksUI().AddSqlServerStorage(builder.Configuration.GetConnectionString("HealthChecksUI:Storage"));var app = builder.Build();// 6. 中间件顺序
app.UseCorrelationId();
app.UseSerilogRequestLogging();
app.UseSentryTracing();
app.UseRouting();app.UseEndpoints(endpoints =>
{endpoints.MapHealthChecks("/health", new HealthCheckOptions{ResponseWriter = UIResponseWriter.WriteHealthCheckUIResponse});endpoints.MapHealthChecksUI(options => { options.UIPath = "/health-ui"; });endpoints.MapControllers();
});app.Run();

日志增强与异常捕获 🛡️

自定义 TenantLogEnricher

public class TenantLogEnricher : ILogEventEnricher
{public void Enrich(LogEvent logEvent, ILogEventPropertyFactory factory){var tenantId    = CurrentTenant.Id?.ToString() ?? "host";var moduleName  = Assembly.GetEntryAssembly()?.GetName().Name ?? "unknown";logEvent.AddPropertyIfAbsent(factory.CreateProperty("TenantId", tenantId));logEvent.AddPropertyIfAbsent(factory.CreateProperty("Module", moduleName));}
}

全局异常订阅器

public class GlobalExceptionSubscriber : IExceptionSubscriber
{private readonly ILogger<GlobalExceptionSubscriber> _logger;public GlobalExceptionSubscriber(ILogger<GlobalExceptionSubscriber> logger)=> _logger = logger;public Task HandleAsync(ExceptionNotificationContext context){// 业务异常也记录，级别 Warning_logger.LogWarning(context.Exception, "业务异常：{Message}", context.Exception.Message);// 全部异常上报到 SentrySentrySdk.CaptureException(context.Exception);return Task.CompletedTask;}
}

---

APM 事务监控示例 🔍

using var tx = SentrySdk.StartTransaction("OrderProcess", "order.process");
try
{// … 业务逻辑 …tx.Finish(SpanStatus.Ok);
}
catch (Exception)
{tx.Finish(SpanStatus.InternalError);throw;
}

---

HealthChecks 与 UI 🩺

// healthchecks-settings.json
{"HealthChecksUI": {"HealthChecks": [{"Name": "ABP Core","Uri": "http://localhost:5000/health"}],"EvaluationTimeOnSeconds": 30,"MinimumSecondsBetweenFailureNotifications": 60,"Storage": {"ConnectionString": "Server=...;Database=HealthChecks;User Id=...;"}}
}

已在 Program.cs 中通过 .AddSqlServerStorage(...) 完成持久化配置。

日志生命周期管理 (ILM) 🔄

# 创建 ILM 策略
PUT _ilm/policy/abp-logs-policy
{"policy": {"phases": {"hot":    { "actions": { "rollover": { "max_age": "7d", "max_size": "50gb" } } },"warm":   { "actions": { "forcemerge": { "max_num_segments": 1 } } },"delete": { "actions": { "delete": { "min_age": "30d" } } }}}
}# 创建 Alias 并激活 Rollover
PUT /abp-logs-write
{"aliases": { "abp-logs": {} }
}

在 appsettings.Production.json 中，将 IndexFormat 修改为:

"IndexFormat": "abp-logs-write-{0:yyyy.MM.dd}"
