Configuring Server
Server
...
configuration is a bit simpler than the client one thanks to the feature class available, OpenTelemetryFeature. Depending on the way the Apache CXF is used to configure JAX-RS services, it could be part of JAX-RS application configuration, for example:
| Code Block | ||||
|---|---|---|---|---|
| ||||
@ApplicationPath("/")
public class CatalogApplication extends Application {
@Override
public Set<Object> getSingletons() {
final SdkTracerProvider sdkTracerProvider = SdkTracerProvider
.builder()
...
.build();
final OpenTelemetry openTelemetry = OpenTelemetrySdk
.builder()
.setTracerProvider(sdkTracerProvider)
...
.buildAndRegisterGlobal();
final Tracer tracer = openTelemetry.getTracer("tracer");
return new HashSet<>(
Arrays.asList(
new OpenTelemetryFeature(openTelemetry, tracer)
)
);
}
} |
Or it could be configured using JAXRSServerFactoryBean as well, for example:
| Code Block | ||||
|---|---|---|---|---|
| ||||
final SdkTracerProvider sdkTracerProvider = SdkTracerProvider
.builder()
...
.build();
final OpenTelemetry openTelemetry = OpenTelemetrySdk
.builder()
.setTracerProvider(sdkTracerProvider)
...
.buildAndRegisterGlobal();
final Tracer tracer = openTelemetry.getTracer("tracer");
final JAXRSServerFactoryBean factory = RuntimeDelegate.getInstance().createEndpoint(/* application instance */, JAXRSServerFactoryBean.class);
factory.setProvider(new OpenTelemetryFeature(openTelemetry, tracer));
...
return factory.create(); |
Once the span processor(s) and sampler are properly configured, all generated spans are going to be collected and available for analysis and/or visualization.TBD
