Skywalking installation and deployment practice

Preface

There are many link tracing tools for microservices , Therefore, the advantages and disadvantages of each tool should be considered when selecting a model , Combined with business needs , Select the best tool .
Link tracking And The selection Zipkin、Pinpoint、SkyWalking、CAT contrast

skywalking The deployment of practice

Configuration in microservices skywalking

rely on

logback Log configuration

IDEA Edit service , To configure JVM Parameters

add to JVM Parameters

-javaagent:D:/work/skywalking/skywalking-agent/skywalking-agent.jar -Dskywalking.agent.service_name=your_service -Dskywalking.collector.backend_service=localhost:11800

Focus on ：
Java agent jar Package path
Your service name （ It will show skywalkingUI)
The backend collects the collector address information of logs ( It's all together , Therefore, you can do without configuration )

The above configuration , Every service needs to add

Running microservices

function skywalking

Enter the downloaded and unzipped skywalking The directory bin Catalog

Enter... In the directory path ： cmd And return
In the command line that comes out, enter startup.bat And return

Simulation of the request

The following is the microservice interface I wrote
http://localhost:9101/getUser/1

View after calling skywalking UI http://localhost:8080/general

View the call topology diagram

View link tracking

Set up skywalking Is stored as elasticsearch

download elasticsearch

download

Unzip and enter bin Directory operation elasticsearch file .

Use localhost:9200 Check to see if startup succeeded
If reality fails , Just go to config/jvm.options The startup memory will be set smaller in the file .

To configure skywalking

Edit the file apache-skywalking-apm-bin\config\application.yml

Modify the above three places , Note that ,namespace Test for the above figure elasticsearch Medium cluster_name Field

restart skywalking that will do .
