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=/manageThe 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:

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

The heapdump endpoint provides a heap dump from the application’s JVM.
10.1. Retrieving the Heap Dump
To retrieve the heap dump, make a GET request to /actuator/heapdump.
The response is binary data and can be large.
Its format depends upon the JVM on which the application is running.
When running on a HotSpot JVM the format is HPROF
and on OpenJ9 it is PHD.
Typically, you should save the response to disk for subsequent analysis.
When using curl, this can be achieved by using the -O option, as shown in the following example:
$ curl 'http://localhost:8080/actuator/heapdump' -OThe preceding example results in a file named heapdump being written to the current working directory.

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
