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=2020-07-24T17%3A18%3A06.292Z&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" : "2020-07-24T17:18:06.297Z",
    "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
