This API documentation describes Spring Boot Actuators web endpoints.

1. Overview

Before you proceed, you should read the following topics:

In order to get the correct JSON responses documented below, Jackson must be available.

1.1. URLs

By default, all web endpoints are available beneath the path /actuator with URLs of the form /actuator/{id}. The /actuator base path can be configured by using the management.endpoints.web.base-path property, as shown in the following example:

management.endpoints.web.base-path=/manage

The preceding application.properties example changes the form of the endpoint URLs from /actuator/{id} to /manage/{id}. For example, the URL info endpoint would become /manage/info.

1.2. Timestamps

All timestamps that are consumed by the endpoints, either as query parameters or in the request body, must be formatted as an offset date and time as specified in ISO 8601.

2. Audit Events (auditevents)

The auditevents endpoint provides information about the application’s audit events.

2.1. Retrieving Audit Events

To retrieve the audit events, make a GET request to /actuator/auditevents, as shown in the following curl-based example:

$ curl 'http://localhost:8080/actuator/auditevents?principal=alice&after=2022-04-21T08%3A50%3A42.834Z&type=logout' -i -X GET

The preceding example retrieves logout events for the principal, alice, that occurred after 09:37 on 7 November 2017 in the UTC timezone. The resulting response is similar to the following:

HTTP/1.1 200 OK
Content-Type: application/vnd.spring-boot.actuator.v3+json
Content-Length: 121

{
  "events" : [ {
    "timestamp" : "2022-04-21T08:50:42.835Z",
    "principal" : "alice",
    "type" : "logout"
  } ]
}

2.1.1. Query Parameters

The endpoint uses query parameters to limit the events that it returns. The following table shows the supported query parameters:

Parameter Description

after

Restricts the events to those that occurred after the given time. Optional.

principal

Restricts the events to those with the given principal. Optional.

type

Restricts the events to those with the given type. Optional.

2.1.2. Response Structure

The response contains details of all of the audit events that matched the query. The following table describes the structure of the response:

Path Type Description

events

Array

An array of audit events.

events.[].timestamp

String

The timestamp of when the event occurred.

events.[].principal

3.1. Retrieving the Beans

To retrieve the beans, make a GET request to /actuator/beans, as shown in the following curl-based example:

$ curl 'http://localhost:8080/actuator/beans' -i -X GET

The resulting response is similar to the following:

Content-Length: 113

{
  "target" : "java.util.concurrent.ConcurrentHashMap",
  "name" : "cities",
  "cacheManager" : "cacheManager"

Parameter Description

cacheManager

Name of the cacheManager to qualify the cache. May be omitted if the cache name is unique.

threads.[].lockInfo.className

String

Fully qualified class name of the lock object.

threads.[].lockInfo.identityHashCode

Number

Identity hash code of the lock object.

threads.[].lockedMonitors

Array

Monitors locked by this thread, if any

threads.[].lockedMonitors.[].className

String

Class name of the lock object.

threads.[].lockedMonitors.[].identityHashCode

Number

Identity hash code of the lock object.

threads.[].lockOwnerName

String

Name of the thread that owns the object on which the thread is blocked, if any.

threads.[].priority

Number

Priority of the thread. Only available on Java 9 or later.

threads.[].stackTrace

Array

Stack trace of the thread.

threads.[].stackTrace.[].classLoaderName

String

Name of the class loader of the class that contains the execution point identified by this entry, if any. Only available on Java 9 or later.

threads.[].stackTrace.[].className

String

Name of the class that contains the execution point identified by this entry.

threads.[].stackTrace.[].fileName

String

Name of the source file that contains the execution point identified by this entry, if any.

threads.[].stackTrace.[].lineNumber

threads.[].stackTrace.[].nativeMethod

Boolean

Whether the execution point is a native method.

threads.[].suspended

Boolean

Whether the thread is suspended.

threads.[].threadId

Number

ID of the thread.

threads.[].threadName

String

Name of the thread.

threads.[].threadState

String

State of the thread (NEW, RUNNABLE, BLOCKED, WAITING, TIMED_WAITING, TERMINATED).

threads.[].waitedCount

Number

Total number of times that the thread has waited for notification.

threads.[].waitedTime

Number

Time in milliseconds that the thread has spent waiting. -1 if thread contention monitoring is disabled

25.2. Retrieving the Thread Dump as Text

To retrieve the thread dump as text, make a GET request to /actuator/threaddump that accepts text/plain, as shown in the following curl-based example:

$ curl 'http://localhost:8080/actuator/threaddump' -i -X GET \
    -H 'Accept: text/plain'

The resulting response is similar to the following:

HTTP/1.1 200 OK
Content-Type: text/plain;charset=UTF-8
Content-Length: 67131
