Before reviewing this article, you need to deploy a Jaeger environment, as follows:

ASP.NET Core link tracing (2) uses SkyAPM integration

OpenTracing protocol

OpenTracing is a distributed tracking protocol that is independent of platform or language, with a unified interface, which is convenient for the development and access of different distributed tracking systems.Zipkin and Jaeger both follow the OpenTracing protocol。

Distributed tracking system Jaeger

Jaeger is a distributed tracking system developed by Uber that is already being used at scale at Uber. And joined the CNCF open source organization on September 13, 2017. Using Jaeger can visualize the call chain of the entire distributed system, which can easily identify and solve problems:

function

Information dissemination in a distributed environment
Distributed transaction monitoring
Demonstrates cross-process call chains
Performance optimization
Locate the problem

characteristic

The advantage of using UDP to transmit data compared to HTTP is that you don't have to worry about Jaeger service downtime or network transmission problems that affect normal business. The disadvantage is packet loss, which affects the entire call chain.
The data is serialized via Thrift or protobuf (gRPC transmission), which is the default: Thrift.

Collection strategy

ConstSampler, full collection
ProbabilisticSampler, probability collection, default to 1 in 10,000
RateLimitingSampler is a rate-limiting acquisition that can only collect a certain amount of data per second
RemotelyControlledSampler is a dynamic collection strategy that adjusts the collection strategy according to the number of visits to the current system

ASP.NET Core is connected to Jaeger link tracing

The project is a framework for .NET Core 3.1, and Nuget installs the following packages:

Among them, OpenTracing.Contrib.NetCore provides the OpenTracing tool for .NET Core-based applications, which is simply an extension, and the main monitoring is as follows:

ASP.NET Core
Entity Framework Core
System.Net.Http (HttpClient)
System.Data.SqlClient
Microsoft.Data.SqlClient

In the Startup file the ConfigureServices method is configured as follows:

var operationName = "Get::api/values/";
var builder = tracer. BuildSpan(operationName);
