Description

Currently response for http://c6401.ambari.apache.org:8080/api/v1/clusters/c/alert_definitions?fields=* is:

{
  "href" : "http://c6401.ambari.apache.org:8080/api/v1/clusters/c/alert_definitions?fields=*",
  "items" : [
    {
      "href" : "http://c6401.ambari.apache.org:8080/api/v1/clusters/c/alert_definitions/1",
      "AlertDefinition" : {
        "cluster_name" : "c",
        "component_name" : "HISTORYSERVER",
        "enabled" : true,
        "id" : 1,
        "interval" : 1,
        "label" : "History Server Web UI",
        "name" : "mapreduce_history_server_webui",
        "scope" : "ANY",
        "service_name" : "MAPREDUCE2",
        "source" : {
          "type" : "WEB"
        }
      }
    }...

but response for http://c6401.ambari.apache.org:8080/api/v1/clusters/c/alert_definitions/1 is:

{
  "href" : "http://c6401.ambari.apache.org:8080/api/v1/clusters/c/alert_definitions/1",
  "AlertDefinition" : {
    "cluster_name" : "c",
    "component_name" : "HISTORYSERVER",
    "enabled" : true,
    "id" : 1,
    "interval" : 1,
    "label" : "History Server Web UI",
    "name" : "mapreduce_history_server_webui",
    "scope" : "ANY",
    "service_name" : "MAPREDUCE2",
    "source" : {
      "reporting" : {
        "ok" : {
          "text" : "HTTP {0} response in {3:.4f} seconds"
        },
        "warning" : {
          "text" : "HTTP {0} response in {3:.4f} seconds"
        },
        "critical" : {
          "text" : "Connection failed to {1}:{2}"
        }
      },
      "type" : "WEB",
      "uri" : {
        "http" : "{{mapred-site/mapreduce.jobhistory.webapp.address}}",
        "https" : "{{mapred-site/mapreduce.jobhistory.webapp.https.address}}",
        "https_property" : "{{mapred-site/mapreduce.jobhistory.http.policy}}",
        "https_property_value" : "HTTPS_ONLY",
        "default_port" : 0.0
      }
    }
  }
}

And for mapping data on UI we need the full source data. Currently we need to make one request for all alert_definitions with all data except source and one request for each alert_definition just to get all source data.
So after this change only one request will be enough to get all alert_definitions data.
