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:

HTTP/1.1 200 OK
Content-Type: application/vnd.spring-boot.actuator.v3+json
Content-Length: 511

{
  "exchanges" : [ {
    "timestamp" : "2022-12-22T13:43:41Z",
    "request" : {
      "uri" : "https://api.example.com",
      "method" : "GET",
      "headers" : {
        "Accept" : [ "application/json" ]
      }
    },
    "response" : {
      "status" : 200,
      "headers" : {
        "Content-Type" : [ "application/json" ]
      }
    },
    "principal" : {
      "name" : "alice"
    },
    "session" : {
      "id" : "d86fa04f-9652-4181-9957-c989cbfbca64"
    },
    "timeTaken" : "PT0.023S"
  } ]
}
