Service endpoints

Services to be checked should be defined in a JSON file as an array of objects. The service has to have a name to be displayed and a statusCheck definition, which is an object that requires the url and httpMethod fields to be defined.

Example configuration:

[
  {
    "name": "integration SIT",
    "statusCheck": {
      "url": "https://127.0.0.1:8081/integration/health",
      "httpMethod": "GET"
     }
  },
  {
    "name": "integration PreProd",
    "statusCheck": {
      "url": "https://127.0.0.1:9080/integration/testpost",

     }
  }
