Spring boot actuator healthcheck (AbstractHealthIndicator) response with indented JSON

I am Spring Boot Actuator /health endpoints to monitor an application but the results is always like that:

"{ "summary" : { "results" : [ ], "duration" : 0, "executionSummaryText" : "Up and running", "failResults" : [ ] }, "applicationID" : "858", "subApplicationID" : "85822", "applicationName" : "app", "subApplicationName" : "app_reg", "applicationVersion" : null, "applicationBuildDate" : "2019-02-28 16:14:09", "applicationBuildLevel" : "5.2.0-SNAPSHOT", "timestamp" : "2019-02-28 17:16:15", "Host" : "host", "workloadStatus" : "Up and running", "detectionTime" : 3, "isaliveStatus" : "ENABLED" }"

but I want it to look like that:

    "{ 
    "summary":
    {
        "results":[],
        "duration":0,
        "executionSummaryText":"Up and running",
        "failResults":[]
    },
        "applicationID":"858",
        "subApplicationID":"85822",
        "applicationName":"app",
        "subApplicationName":"app_reg",
        "applicationVersion":null,
        "applicationBuildDate":"2019-02-28 13:19:35",
        "applicationBuildLevel":"5.2.0-SNAPSHOT",
        "timestamp":"2019-02-28 14:21:33",
        "Host":"host",
        "workloadStatus":"Up and running",
        "detectionTime":4,
        "isaliveStatus":"ENABLED"
     }"

I tried all of the following but it did not work:

http.mappers.jsonPrettyPrint=true

spring.jackson.serialization.indent_output=true

objectMapper.enable(SerializationFeature.INDENT_OUTPUT);

but none of them worked. Is there a configuration to make it work for JSON output?

You need to enable INDENT_OUTPUT serialization feature using properties available in the Appendix A. Assuming you have not created the ObjectMapper bean yourself as per this guide the Spring Boot property is: 

spring.jackson.serialization.indent_output=true

Do note this is a global change affect all endpoints which are returning JSON by serializing objects with Jackson.
