Tracing

Use jaeger for tracing

jaeger is a distributed tracking system inspired by Dapper and Zipkin developed by Uber. It complies with the opentracing specification and is a distributed link tracking solution.

SolarMesh’s core business is traffic monitoring between cloud services. Jaeger can enhance SolarMesh’s observation capabilities in a certain traffic request scenario, which has positive significance for the scheduling of internal service interfaces, problem analysis, and performance optimization.

In SolarMesh, jaeger enhances the following functions

  • Distributed tracing information delivery
  • Distributed transaction monitoring
  • problem analysis
  • Service dependency analysis
  • Performance optimization

Install jaeger

Install jaeger using solarctl

solarctl install jaeger --name <cluster name: cluster01>

After successful installation, the jaeger server will be installed in the cluster. The default namespace is service-mesh. It is recommended to use jaeger.service-mesh:6831 to send span data

$ kubectl get svc -n service-mesh
NAME               TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)                                                                      AGE
jaeger             ClusterIP   10.96.74.5      <none>        5775/UDP,6831/UDP,6832/UDP,5778/TCP,16686/TCP,14268/TCP,14250/TCP,9411/TCP   65s
Port Protocol Component Function
5775 UDP agent accept zipkin.thrift over compact thrift protocol (deprecated, used by legacy clients only)
6831 UDP agent accept jaeger.thrift over compact thrift protocol
6832 UDP agent accept jaeger.thrift over binary thrift protocol
5778 HTTP agent serve configs
16686 HTTP query serve frontend
14268 HTTP collector accept jaeger.thrift directly from clients
14250 HTTP collector accept model.proto
9411 HTTP collector Zipkin compatible endpoint (optional)

Use jaeger to enhance solarmesh

After SolarMesh installs jaeger, the jaeger icon will appear in the add-on component on the Service List page.

Click the jaeger icon to access the jaeger interface of the corresponding service. Here we click the jaeger icon of the reviews service.
