[source,js]
--------------------------------------------------
PUT _xpack/ml/anomaly_detectors/it-ops-kpi
{
    "description":"First simple job",
    "analysis_config":{
      "bucket_span": "5m",
      "latency": "0ms",
      "detectors":[
        {
          "detector_description": "low_sum(events_per_min)",
          "function":"low_sum",
          "field_name": "events_per_min"
        }
      ]
    },
    "data_description": {
