opentracing

问题 I would like to configure Jaeger in my Spring application. Somehow I cannot find a proper way to do this. Almost all Spring-Jaeger-related documentation is for Spring Boot where most of the properties are auto configured. Here's my approach. Maven dependency: <dependency> <groupId>io.opentracing.contrib</groupId> <artifactId>opentracing-spring-jaeger-cloud-starter</artifactId> <version>1.0.3</version> </dependency> Spring config for Jaeger: @Configuration public class JagerConfiguration {

问题 I am trying to implement a Go-based microservice system. I have two service and I try to Inject and Extract span data. In my first service, I have: func (apitracer apiTracer) validatemail(res http.ResponseWriter, req *http.Request) { validateEmailSpan := apitracer.tracer.StartSpan("Validate Email") apitracer.tracer.Inject( validateEmailSpan.Context(), opentracing.HTTPHeaders, opentracing.HTTPHeadersCarrier(req.Header)) req.Header.Set("Content-Type", "application/x-www-form-urlencoded") resp,

问题 In my project, I try to implement distributed tracing using opentracing . My microservice has following structure. -- API-Gateway |_ User-Service |_ Notification In my API-gateway, I start and in API gateway, I use a to a function to start tracing, code is taken from Setting up your tracer in main() : gatewayTracer := &apiTracer{tracer: startTracing("API Gateway")} http.HandleFunc("/getemail", gatewayTracer.validatemail) func (apitracer apiTracer) validatemail(res http.ResponseWriter, req

问题 Based on this and this How would I enable tracing for reactive-sql-clients ? Now use %dev.quarkus.datasource.url=vertx-reactive:postgresql://dev-db-server:5432/mydb - it works, but no tracing support though. I can see racing for my rest calls but not the db. Tried to use %dev.quarkus.datasource.url=vertx-reactive:tracing:postgresql://dev-db-server:5432/mydb my deps: <dependency> <groupId>io.quarkus</groupId> <artifactId>quarkus-smallrye-openapi</artifactId> </dependency> <dependency> <groupId

问题 My API-gateway starts a tracer and a span for validate email. Then its passed to user-service for validation. I want to pass this span details to user-service as a json object and start another span as a tracer.start_span('Validate Email', child_of=API_gateway_span) To do it, I have used following struct: type checkEmail struct { GatewayTracerSpan opentracing.SpanContext `json: gatewayTracerSpan` Email string `json: email` Uuid string `json: uuid` } In function() validateEmailSpan :=

问题 We are trying to go reactive with Webflux. We are using Jaegar with Istio for instrumentation purposes. Jaegar understands Spring MVC endpoints well, but don't seem to work at all for WebFlux. I am looking for suggestions to make my webflux endpoints appear in Jaeger. Thanks in advance. 回答1: The best way to move forward in order to use Jaegar is NOT TO USE JAEGAR CLIENT! Jaegar has the ability to collect Zipkin spans: https://www.jaegertracing.io/docs/1.8/getting-started/#migrating-from

问题 I have tried executing this docker command to setup Jaeger Agent and jaeger collector with elasticsearch. sudo docker run \ -p 5775:5775/udp \ -p 6831:6831/udp \ -p 6832:6832/udp \ -p 5778:5778 \ -p 16686:16686 \ -p 14268:14268 \ -e SPAN_STORAGE_TYPE=elasticsearch \ --name=jaeger \ jaegertracing/all-in-one:latest but this command gives the below error.

问题 I'm currently looking into different openTracing Tracer-Implementations. I want to use uber/jaeger-client-node but the backend won't receive my traces. Here is what I did: I started the all-in-one docker image: docker run -d -p5775:5775/udp -p16686:16686 jaegertracing/all-in-one:latest Next, i wrote a simple example application: Gist But when I go to Jaeger UI, nothing is shown about the example service. What did I do wrong? Thanks 回答1: There are two issues here. One is that your code sets
