I am trying to use RUM on the spring-boot application https://github.com/spring-projects/spring-petclinic. I would like to link the transactions from the Client side (i.e. JavaScript) to the Server side (i.e. Java).
From the documentation I found that I could do this with distributet tracing. I also looked at this blog entry for instructions on how to do this.
On the Client side I configured the RUM-agent as follows:
<script src="https://unpkg.com/@elastic/apm-rum@5.9.1/dist/bundles/elastic-apm-rum.umd.min.js"></script>
<script>
elasticApm.init({
serviceName: 'PetClinic',
serviceVersion: '1.0',
serverUrl: 'http://localhost:8200', // APM server
transactionThrottleInterval: 1,
// distributedTracingOrigins: ['localhost:8080', 'http://localhost:8080', 'http://localhost:8080/'],
propagateTracestate: true
})
</script>
On the Server side I configured the HTTP-Headers and HTTP-Methods as described in this blog entry.
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;
import java.util.logging.Level;
import java.util.logging.Logger;
@Configuration
public class MyCorsConfiguration {
@Bean
public FilterRegistrationBean<CorsFilter> corsFilter() {
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
CorsConfiguration config = new CorsConfiguration();
config.setAllowCredentials(true);
config.addAllowedOrigin("*");
config.addAllowedHeader("*");
config.addAllowedMethod("*");
source.registerCorsConfiguration("/**", config);
FilterRegistrationBean<CorsFilter> bean = new FilterRegistrationBean<>(new CorsFilter(source));
bean.setOrder(0);
Logger.getLogger(MyCorsConfiguration.class.getName()).log(Level.INFO, "Add CORS configuration");
return bean;
}
}
The server is started with the Java elastic APM agent to monitor the Server side operations.
-javaagent:path/to/elastic-apm-agent-1.26.0.jar
-Delastic.apm.service_name=PetClinic
-Delastic.apm.application_packages=org.springframework.samples.petclinic.*
-Delastic.apm.server_url=http://localhost:8200
-Delastic.apm.capture_body=all
-Delastic.apm.metrics_interval=0s
-Delastic.apm.trace_methods=org.springframework.samples.petclinic.*
Unfortunately, the HTTP requests that are recorded on the server side to not contain the traceparent or tracestate headers.

If I understood the documentation correctly traceparent and tracestate should be added to the HTTP-Headers of the requests. Am I correct in that understanding or did I get something wrong here?
Does anyone know what is wrong or missing in my configuration?
APM Agent language and version:
JavaScript; v 5.9.1
Java; v 1.26.0
Browser version:
I tried it with Firefox 93.0 (64-Bit)
and Chrome Version 95.0.4638.69 (Official Build) (64-bit)
Thanks for reading!
