Observability
Spring Security integrates with Spring Observability out-of-the-box for tracing; though it’s also quite simple to configure for gathering metrics.
Tracing
When an ObservationRegistry
bean is present, Spring Security creates traces for:
-
the filter chain
-
the
AuthenticationManager
, and -
the
AuthorizationManager
Boot Integration
For example, consider a simple Boot application:
-
Java
-
Kotlin
@SpringBootApplication
public class MyApplication {
@Bean
public UserDetailsService userDetailsService() {
return new InMemoryUserDetailsManager(
User.withDefaultPasswordEncoder()
.username("user")
.password("password")
.authorities("app")
.build()
);
}
@Bean
ObservationRegistryCustomizer<ObservationRegistry> addTextHandler() {
return (registry) -> registry.observationConfig().observationHandler(new ObservationTextPublisher());
}
public static void main(String[] args) {
SpringApplication.run(ListenerSamplesApplication.class, args);
}
}
@SpringBootApplication
class MyApplication {
@Bean
fun userDetailsService(): UserDetailsService {
InMemoryUserDetailsManager(
User.withDefaultPasswordEncoder()
.username("user")
.password("password")
.authorities("app")
.build()
);
}
@Bean
fun addTextHandler(): ObservationRegistryCustomizer<ObservationRegistry> {
return registry: ObservationRegistry -> registry.observationConfig()
.observationHandler(ObservationTextPublisher());
}
fun main(args: Array<String>) {
runApplication<MyApplication>(*args)
}
}
And a corresponding request:
?> http -a user:password :8080
Will produce the following output (indentation added for clarity):

Manual Configuration
For a non-Spring Boot application, or to override the existing Boot configuration, you can publish your own ObservationRegistry
and Spring Security will still pick it up.
-
Java
-
Kotlin
-
Xml
@SpringBootApplication
public class MyApplication {
@Bean
public UserDetailsService userDetailsService() {
return new InMemoryUserDetailsManager(
User.withDefaultPasswordEncoder()
.username("user")
.password("password")
.authorities("app")
.build()
);
}
@Bean
ObservationRegistry<ObservationRegistry> observationRegistry() {
ObservationRegistry registry = ObservationRegistry.create();
registry.observationConfig().observationHandler(new ObservationTextPublisher());
return registry;
}
public static void main(String[] args) {
SpringApplication.run(ListenerSamplesApplication.class, args);
}
}
@SpringBootApplication
class MyApplication {
@Bean
fun userDetailsService(): UserDetailsService {
InMemoryUserDetailsManager(
User.withDefaultPasswordEncoder()
.username("user")
.password("password")
.authorities("app")
.build()
);
}
@Bean
fun observationRegistry(): ObservationRegistry<ObservationRegistry> {
ObservationRegistry registry = ObservationRegistry.create()
registry.observationConfig().observationHandler(ObservationTextPublisher())
return registry
}
fun main(args: Array<String>) {
runApplication<MyApplication>(*args)
}
}
<sec:http auto-config="true" observation-registry-ref="ref">
<sec:intercept-url pattern="/**" access="authenticated"/>
</sec:http>
<!-- define and configure ObservationRegistry bean -->
Disabling Observability
If you don’t want any Spring Security observations, in a Spring Boot application you can publish a ObservationRegistry.NOOP
@Bean
.
However, this may turn off observations for more than just Spring Security.
Instead, you can alter the provided ObservationRegistry
with an ObservationPredicate
like the following:
-
Java
-
Kotlin
@Bean
ObservationRegistryCustomizer<ObservationRegistry> noSpringSecurityObservations() {
ObservationPredicate predicate = (name, context) -> !name.startsWith("spring.security.");
return (registry) -> registry.observationConfig().observationPredicate(predicate);
}
@Bean
fun noSpringSecurityObservations(): ObservationRegistryCustomizer<ObservationRegistry> {
ObservationPredicate predicate = (name: String, context: Observation.Context) -> !name.startsWith("spring.security.")
(registry: ObservationRegistry) -> registry.observationConfig().observationPredicate(predicate)
}
There is no facility for disabling observations with XML support.
Instead, simply do not set the observation-registry-ref attribute.

Trace Listing
Spring Security tracks the following spans on each request:
-
spring.security.http.requests
- a span that wraps the entire filter chain, including the request -
spring.security.http.chains.before
- a span that wraps the receiving part of the security filters -
spring.security.http.chains.after
- a span that wraps the returning part of the security filters -
spring.security.http.secured.requests
- a span that wraps the now-secured application request -
spring.security.http.unsecured.requests
- a span that wraps requests that Spring Security does not secure -
spring.security.authentications
- a span that wraps authentication attempts -
spring.security.authorizations
- a span that wraps authorization attempts
spring.security.http.chains.before + spring.security.http.secured.requests + spring.security.http.chains.after = spring.security.http.requests
spring.security.http.chains.before + spring.security.http.chains.after = Spring Security’s part of the request
