Search Anomaly Detectors tool

Introduced 2.13

The SearchAnomalyDetectorsTool retrieves information about anomaly detectors set up on your cluster. For more information about anomaly detectors, see Anomaly detection.

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

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_Detectors_Tool",
  "type": "flow",
  "description": "this is a test agent for the SearchAnomalyDetectorsTool",
  "memory": {
    "type": "demo"
  },
  "tools": [
      {
      "type": "SearchAnomalyDetectorsTool",
      "name": "DemoSearchAnomalyDetectorsTool",
      "parameters": {}
    }
  ]
}

For parameter descriptions, see Register parameters.

OpenSearch responds with an agent ID:

{
  "agent_id": "EuJYYo0B9RaBCvhuy1q8"
}

Step 2: Run the agent

Run the agent by sending the following request:

POST /_plugins/_ml/agents/EuJYYo0B9RaBCvhuy1q8/_execute
{
  "parameters": {
    "question": "Do I have any anomaly detectors?"
  }
}

OpenSearch responds with a list of anomaly detectors set up on your cluster and the total number of anomaly detectors:

{
  "inference_results": [
    {
      "output": [
        {
          "name": "response",
          "result": "AnomalyDetectors=[{id=y2M-Yo0B-yCFzT-N_XXU,name=sample-http-responses-detector,type=SINGLE_ENTITY,description=A sample detector to detect anomalies with HTTP response code logs.,index=[sample-http-responses],lastUpdateTime=1706750311891}]TotalAnomalyDetectors=1"
        }
      ]
    }
  ]
}
