             Summary: UI: REST API Changes in Storm
                 Key: AMBARI-7721
                 URL: https://issues.apache.org/jira/browse/AMBARI-7721
             Project: Ambari
          Issue Type: Bug
          Components: ambari-web
    Affects Versions: 1.7.0
            Reporter: Oleg Nechiporenko
            Assignee: Oleg Nechiporenko
            Priority: Critical
             Fix For: 1.7.0


We need to make changes for Storm rest api metrics from UI side.
In stack 2.2 STORM_REST_API will not be included. All api calls will be added to STORM_UI_SERVER.

Example:
{code}
http://c6402.ambari.apache.org:8080/api/v1/clusters/c1/hosts/c6402.ambari.apache.org/host_components/STORM_UI_SERVER
{code}

{code}
"metrics" : {
    "api" : {
      "v1" : {
        "cluster" : {
          "summary" : {
            "executorsTotal" : 28.0,
            "nimbusUptime" : "15m 1s",
            "slotsFree" : 0.0,
            "slotsTotal" : 2.0,
            "slotsUsed" : 2.0,
            "supervisors" : 1.0,
            "tasksTotal" : 28.0
          }
        },
        "topology" : {
          "summary" : [
            {
              "executorsTotal" : 28.0,
              "uptime" : "5m 59s",
              "schedulerInfo" : null,
              "name" : "WordCountida8c06640_date2901141",
              "workersTotal" : 2.0,
              "status" : "ACTIVE",
              "owner" : "",
              "tasksTotal" : 28.0,
              "id" : "WordCountida8c06640_date2901141-2-1412195707"
            }
          ]
        }
      }
{code}

Note: Now we need to calculate a number of topologies from this data.
