Automatic Instrumentation
Learn what transactions are captured after tracing is enabled.
Capturing transactions requires that you first set up tracing if you haven't already.
Sentry Spring Boot integration, once enabled, captures each incoming Spring MVC HTTP request and turns it into a transaction with SentryTracingFilter. Transaction names follow pattern <HTTP method> <Spring MVC route>, for example for a request to a following controller:
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
@RestController
class HelloController {
@GetMapping("/person/{id}")
Person person(@PathVariable Long id) {
...
}
}
Each sampled request executed by this controller method will be turned into a transaction GET /person/{id}.
Sentry Spring Boot integration provides SentrySpanRestTemplateCustomizer that creates a span for each outgoing HTTP request executed with a RestTemplate. To use instrumented RestTemplate make sure to create RestTemplate beans using RestTemplateBuilder:
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Bean;
import org.springframework.boot.web.client.RestTemplateBuilder;
import org.springframework.web.client.RestTemplate;
@Configuration
class AppConfig {
@Bean
RestTemplate restTemplate(RestTemplateBuilder builder) {
return builder.build();
}
}
Sentry Spring Boot integration provides SentrySpanRestClientCustomizer that creates a span for each outgoing HTTP request executed with a RestClient. To use instrumented RestClient make sure to create RestClient beans using RestClient.Builder:
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Bean;
import org.springframework.web.client.RestClient;
@Configuration
class AppConfig {
@Bean
RestClient restClient(RestClient.Builder builder) {
return builder.build();
}
}
Sentry Spring Boot integration provides SentrySpanWebClientCustomizer that creates a span for each outgoing HTTP request executed with a WebClient. To use instrumented WebClient make sure to create WebClient beans using WebClient.Builder:
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Bean;
import org.springframework.web.reactive.function.client.WebClient;
@Configuration
class AppConfig {
@Bean
WebClient webClient(WebClient.Builder builder) {
return builder.build();
}
}
