Get trained models usage info Generally available

GET /_ml/trained_models/_stats

You can get usage information for multiple trained models in a single API request by using a comma-separated list of model IDs or a wildcard expression.

Required authorization

  • Cluster privileges: monitor_ml

Query parameters

  • allow_no_match boolean

    Specifies what to do when the request:

    • Contains wildcard expressions and there are no models that match.
    • Contains the _all string or no identifiers and there are no matches.
    • Contains wildcard expressions and there are only partial matches.

    If true, it returns an empty array when there are no matches and the subset of results when there are partial matches.

  • from number

    Skips the specified number of models.

  • size number

    Specifies the maximum number of models to obtain.

Responses

  • 200 application/json
    Hide response attributes Show response attributes object
    • count number Required

      The total number of trained model statistics that matched the requested ID patterns. Could be higher than the number of items in the trained_model_stats array as the size of the array is restricted by the supplied size parameter.

    • trained_model_stats array[object] Required

      An array of trained model statistics, which are sorted by the model_id value in ascending order.

          • min_number_of_allocations number

            Specifies the minimum number of allocations to scale to. If set, it must be greater than or equal to 0. If not defined, the deployment scales to 0.

          • max_number_of_allocations number

            Specifies the maximum number of allocations to scale to. If set, it must be greater than or equal to min_number_of_allocations.

          • allocation_count number Required

            The current number of nodes where the model is allocated.

            Values are started, starting, or fully_allocated.

          • target_allocation_count number Required

            The desired number of nodes for model allocation.

        • cache_size number | string

        • model_id string Required
        • nodes array[object] Required

          The deployment stats for each node that currently has the model allocated. In serverless, stats are reported for a single unnamed virtual node.

          • average_inference_time_ms_last_minute
          • average_inference_time_ms_excluding_cache_hits
          • error_count number

            The number of errors when evaluating the trained model.

          • inference_count number

            The total number of inference calls made against this node for this model.

          • inference_cache_hit_count number
          • inference_cache_hit_count_last_minute number
          • last_access
          • number_of_allocations number

            The number of allocations assigned to this node.

          • number_of_pending_requests number

            The number of inference requests queued to be processed.

          • peak_throughput_per_minute number Required
          • rejected_execution_count number

            The number of inference requests that were not processed because the queue was full.

          • routing_state object Required
          • start_time
          • threads_per_allocation number

            The number of threads used by each allocation during inference.

          • throughput_last_minute number Required
          • timeout_count number

            The number of inference requests that timed out before being processed.

        • number_of_allocations number

          The number of allocations requested.

        • peak_throughput_per_minute number Required

        • rejected_execution_count number

          The sum of rejected_execution_count for all nodes in the deployment. Individual nodes reject an inference request if the inference queue is full. The queue size is controlled by the queue_capacity setting in the start trained model deployment API.

        • reason string

          The reason for the current deployment state. Usually only populated when the model is not deployed to a node.

        • start_time number

        • cache_miss_count number Required

          The number of times the model was loaded for inference and was not retrieved from the cache. If this number is close to the inference_count, the cache is not being appropriately used. This can be solved by increasing the cache size or its time-to-live (TTL). Refer to general machine learning settings for the appropriate settings.

          The number of failures when using the model for inference.

        • inference_count number Required

          The number of inference calls where all the training features for the model were missing.

        • timestamp number

          Time unit for milliseconds

      • ingest object

        A collection of ingest stats for the model across all nodes. The values are summations of the individual node statistics. The format matches the ingest section in the nodes stats API.
