Path parameters

• model_id string | array[string] Required

  The unique identifier of the trained model or a model alias. It can be a comma-separated list or a wildcard expression.

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

  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.

        • allocation_count number Required

          The current number of nodes where the model is allocated.

        • state string Required

          Values are started, starting, or fully_allocated.

        • target_allocation_count number Required

          The desired number of nodes for model allocation.

      • cache_size number | string

        One of:

        _types:ByteSize number _types:ByteSize string
      • deployment_id string Required
      • error_count number Required

        The sum of error_count for all nodes in the deployment.

      • inference_count number Required

        The sum of inference_count for all nodes in the deployment.

      • 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
        • error_count number Required

          The number of errors when evaluating the trained model.

        • inference_count number Required

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

        • last_access number Required

          The epoch time stamp of the last inference call for the model on this node.

        • number_of_allocations number Required

          The number of allocations assigned to this node.

        • number_of_pending_requests number Required

          The number of inference requests queued to be processed.

        • rejection_execution_count number Required

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

        • routing_state object Required
        • start_time
        • threads_per_allocation number Required

          The number of threads used by each allocation during inference.

        • timeout_count number Required

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

      • number_of_allocations number Required

        The number of allocations requested.

      • queue_capacity number Required

        The number of inference requests that can be queued before new requests are rejected.

      • rejected_execution_count number Required

        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 Required

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

      • start_time number

        Time unit for milliseconds

      • state string Required

        Values are started, starting, or stopping.

      • threads_per_allocation number Required

        The number of threads used be each allocation during inference.

      • timeout_count number Required

        The sum of timeout_count for all nodes in the deployment.

    • inference_stats object
      Hide inference_stats attributes Show inference_stats attributes object

      • 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.

      • failure_count number Required

        The number of failures when using the model for inference.

      • inference_count number Required

        The total number of times the model has been called for inference. This is across all inference contexts, including all pipelines.

      • missing_all_fields_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.
