Tlog helps Pangu framework realize microservice link log tracking

With the popularity of microservices , Many companies break down their systems into many micro services according to their business boundaries . Therefore, the service link runs through many microservice nodes , As a result, it becomes very difficult to locate the logs of a request and upstream and downstream services . To solve this pain ,  There are also many mature solutions in the industry . Such as  SkyWalking,Pinpoint  etc. , But its operation and maintenance costs and data storage costs can not be underestimated . If there are corresponding resources to do so, they are naturally the best choice .  But if you have limited resources , So here is a very lightweight integration  TLog  To solve the problem of log tracking .

TLog  What is it? ？

TLog  Provides the simplest way to solve the problem of log tracking , It doesn't collect logs , There's no need for additional storage space , It just automatically tags your logs , Automatic generation  TraceId  Throughout the entire link of your microservice . And provide upstream and downstream node information .

Integrate  TLog

Pangu development framework has  TLog  Integrated into the Pangu foundation module as the default standard component ：

pangu-spring-boot-starter

.

How to use

First step ： Rely on Pangu basic module

<dependency>
 <groupId>com.gitee.pulanos.pangu</groupId>
 <artifactId>pangu-spring-boot-starter</artifactId>
</dependency>


The second step ： The startup class invokes the log enhancement method

static {
 AspectLogEnhance.enhance();
}


The third step ： Construct Pangu consumer micro service and producer micro service respectively

See the following Pangu example module .

Get the code

• pangu-examples-dubbo-service  Service producer

• pangu-examples-webapi-dubbo-service-based  Serving consumers

View the log output effect

We're in a  Dubbo  Serving consumers and a  Dubbo  After the above configurations are made in the service producer application , You can see in the log of each call chain  TLog  Custom embedded  TraceId  Label value
