HTTP Exchanges (httpexchanges)

The httpexchanges endpoint provides information about HTTP request-response exchanges.

Retrieving the HTTP Exchanges

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

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

The resulting response is similar to the following:

Content-Type: application/vnd.spring-boot.actuator.v3+json
Content-Length: 511

  "exchanges" : [ {
