Search Anomaly Results tool

Introduced 2.12

This is an experimental feature and is not recommended for use in a production environment. For updates on the progress of the feature or if you want to leave feedback, see the associated GitHub issue.

The SearchAnomalyResultsTool retrieves information about anomaly detector results. For more information about anomaly detectors, see Anomaly detection.

Step 1: Register a flow agent that will run the SearchAnomalyResultsTool

A flow agent runs a sequence of tools in order and returns the last tool’s output. To create a flow agent, send the following register agent request:

POST /_plugins/_ml/agents/_register
{
  "name": "Test_Agent_For_Search_Anomaly_Results_Tool",
  "type": "flow",
  "description": "this is a test agent for the SearchAnomalyResultsTool",
  "memory": {
    "type": "demo"
  },
  "tools": [
    {
      "type": "SearchAnomalyResultsTool",
      "name": "DemoSearchAnomalyResultsTool",
      "parameters": {}
    }
  ]
}

copy

For parameter descriptions, see Register parameters.

OpenSearch responds with an agent ID:

{
  "agent_id": "HuJZYo0B9RaBCvhuUlpy"
}

Step 2: Run the agent

Run the agent by sending the following request:

POST /_plugins/_ml/agents/HuJZYo0B9RaBCvhuUlpy/_execute
{
  "parameters": {
    "question": "Do I have any anomalies?"
  }
}

copy

OpenSearch responds with a list of individual anomaly detectors set up on your cluster (where each result contains the detector ID, the anomaly grade, and the confidence level) and the total number of anomaly results found:

{
  "inference_results": [
    {
      "output": [
        {
          "name": "response",
          "result": "AnomalyResults=[{detectorId=ef9lYo0Bk4MTqircmjnm,grade=1.0,confidence=0.9403051246569198}{detectorId=E-JlYo0B9RaBCvhunFtw,grade=1.0,confidence=0.9163498216870274}]TotalAnomalyResults=2"
        }
      ]
    }
  ]
}

If no anomalies are found, OpenSearch responds with an empty array in the results:

{
  "inference_results": [
    {
      "output": [
        {
          "name": "response",
          "result": "AnomalyResults=[]TotalAnomalyResults=0"
        }
      ]
    }
  ]
}
