برای پیاده سازی distributed tracing، میتوانیم از ابزار متن باز و محبوب Jaeger (با تلفظ یِگِر) که ابتدا توسط شرکت Uber منتشر شد، استفاده کنیم. نحوه کارکرد Jaeger بصورت زیر میباشد:
ساده‌ترین روش برای راه‌اندازی Jager، استفاده از داکر ایمیج All in one که شامل ماژول های agent ، collector، query و ui است. پورت 6831 مربوط به agent و پورت 16686 مربوط به ui میباشد. برای جزئیات مربوط به ماژول‌های مختلف از این لینک استفاده کنید.
docker run -d -p 6831:6831/udp -p 6832:6832/udp -p 14268:14268 -p 14250:14250 -p 16686:16686 -p 5778:5778 --name jaeger jaegertracing/all-in-one:latest
بعد از اجرای دستور بالا، اطلاعات مربوط به سرویس‌ها و trace ها در ماژول Jager UI با آدرس http://localhost:16686 قابل مشاهده است.
جهت استفاده از Jaeger از پروژه تستی که شامل دو سرویس User و Gateway میباشد، استفاده میکنیم. در سرویس User، متد AddUser در صورت عدم وجود کاربر در دیتابیس، اطلاعات کاربر از گیت‌هاب را دریافت و در دیتابیس ذخیره می‌کند. سرویس Gateway از Ocelot برای مسیردهی درخواست‌ها استفاده می‌کند. برای آشنایی با ocelot این پست را مطالعه نمایید.
public async Task<ApiResult<Models.User>> AddUserAsync(string username)
{
var result = new ApiResult<Models.User>();
var user = await _applicationDbContext.Users.FirstOrDefaultAsync(x => x.Login == username);
if (user is null)
{
try
{
var url = string.Format(_appConfig.Github.ProfileUrl, username);
var apiResult = await _httpClient.GetStringAsync(url);
var userDto = JsonSerializer.Deserialize<UserDto>(apiResult);
user = _mapper.Map<Models.User>(userDto);
await _applicationDbContext.Users.AddAsync(user);
await _applicationDbContext.SaveChangesAsync();
result.Result = user;
result.Message = "User successfully Created";
return result;
}
catch (Exception e)
{
result.Message = "User not found";
return result;
}
}
result.Message = "User already exist";
result.Result = user;
return result;
}
برای ثبت Trace مربوط به درخواست‌ها در Jaeger ، بعد از نصب پکیج‌های Jaeger و OpenTracing.Contrib.NetCore در هر دو سرویس، در کانفیگ هریک از سرویس‌ها مورد زیر را اضافه میکنیم:
"JaegerConfig": {
"Host": "localhost",
"Port": 6831,
"IsEnabled": true,
"SamplingRate": 0.5
}
و برای اضافه شدن tracer به برنامه از متد الحاقی زیر استفاده میکنیم:
public static class Extensions
{
public static void AddJaeger(this IServiceCollection services, IConfiguration configuration)
{
var config = configuration.GetSection("JaegerConfig").Get<JaegerConfig>();
if (!(config?.IsEnabled ?? false))
return;
if (string.IsNullOrEmpty(config?.Host))
throw new Exception("invalid JaegerConfig");
services.AddSingleton<ITracer>(serviceProvider =>
{
string serviceName = Assembly.GetEntryAssembly()?.GetName().Name;
ILoggerFactory loggerFactory = serviceProvider.GetRequiredService<ILoggerFactory>();
var sampler = new ProbabilisticSampler(config.SamplingRate);
var reporter = new RemoteReporter.Builder()
.WithLoggerFactory(loggerFactory)
.WithSender(new UdpSender(config.Host, config.Port, 0))
.WithFlushInterval(TimeSpan.FromSeconds(15))
.WithMaxQueueSize(300)
.Build();
ITracer tracer = new Tracer.Builder(serviceName)
.WithLoggerFactory(loggerFactory)
.WithSampler(sampler)
.WithReporter(reporter)
.Build();
GlobalTracer.Register(tracer);
return tracer;
});
services.AddOpenTracing();
}
}
برای ثبت traceها استراتژی‌های متفاوتی وجود دارد. در اینجا از ProbabilisticSampler استفاده شده‌است که در سازنده‌ی آن می‌توان درصد ثبت Traceها را مقدار دهی کرد. در نهایت این متد الحاقی را در Startup اضافه میکنیم:
builder.Services.AddJaeger(builder.Configuration);
بعد از اجرای پروژه و فراخوانی https://localhost:6000/gateway/Users/Add ، سرویس Gateway، درخواست را به سرویس User ارسال می‌کند و این سرویس‌ها در Jaeger UI قابل مشاهده هستند.
جهت مشاهده trace ها ، سرویس مورد نظر را انتخاب و روی Find Traces کلیک کنید. با کلیک روی Trace مورد نظر، جزئیات فعالیت هایی مثل فراخوانی سرویس و مراجعه به دیتابیس قابل مشاهده است.
برای اضافه کردن لاگ سفارشی به یک span، می‌توان از اینترفیس ITracer استفاده کرد:
private readonly IUserService _userService;
private readonly ITracer _tracer;
public UsersController(IUserService userService, ITracer tracer)
{
_userService = userService;
_tracer = tracer;
} [HttpPost]
public async Task<ActionResult> AddUser(AddUserDto model)
{
var actionName = ControllerContext.ActionDescriptor.DisplayName;
using var scope = _tracer.BuildSpan(actionName).StartActive(true);
scope.Span.Log($"Add user log username: {model.Username}");
return Ok(await _userService.AddUserAsync(model.Username));
}
