Explain the shard allocations Added in 5.0.0

GET /_cluster/allocation/explain
Api key auth Basic auth Bearer auth

Get explanations for shard allocations in the cluster. For unassigned shards, it provides an explanation for why the shard is unassigned. For assigned shards, it provides an explanation for why the shard is remaining on its current node and has not moved or rebalanced to another node. This API can be very useful when attempting to diagnose why a shard is unassigned or why a shard continues to remain on its current node when you might expect otherwise.

Query parameters

application/json

Body

  • current_node string

    Specifies the node ID or the name of the node to only explain a shard that is currently located on the specified node.

  • index string
  • primary boolean

    If true, returns explanation for the primary shard for the given shard ID.

  • shard number

    Specifies the ID of the shard that you would like an explanation for.

          A string that contains each boundary character.

        • boundary_max_scan number

          How far to scan for boundary characters.

        • boundary_scanner string

          Values are chars, sentence, or word.

        • boundary_scanner_locale string

          Controls which locale is used to search for sentence and word boundaries. This parameter takes a form of a language tag, for example: "en-US", "fr-FR", "ja-JP".

Get aliases

GET /_alias
Api key auth Basic auth Bearer auth

Retrieves information for one or more data stream or index aliases.

Query parameters

  • allow_no_indices boolean

    If false, the request returns an error if any wildcard expression, index alias, or _all value targets only missing or closed indices. This behavior applies even if the request targets other open indices.

  • expand_wildcards string | array[string]

    Type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. Supports comma-separated values, such as open,hidden. Valid values are: all, open, closed, hidden, none.

  • ignore_unavailable boolean

    If false, the request returns an error if it targets a missing or closed index.

  • master_timeout string

    Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.

            External documentation
          • index_routing string

            Value used to route indexing operations to a specific shard. If specified, this overwrites the routing value for indexing operations.

          • is_write_index boolean

            If true, the index is the write index for the alias.

          • routing string

            Value used to route indexing and search operations to a specific shard.

          • search_routing string

            Value used to route search operations to a specific shard. If specified, this overwrites the routing value for search operations.

          • is_hidden boolean

            If true, the alias is hidden. All indices for the alias must have the same is_hidden value.

Get data frame analytics job configuration info Added in 7.3.0

GET /_ml/data_frame/analytics/{id}
Api key auth Basic auth Bearer auth

You can get information for multiple data frame analytics jobs in a single API request by using a comma-separated list of data frame analytics jobs or a wildcard expression.

Path parameters

  • id string Required

    Identifier for the data frame analytics job. If you do not specify this option, the API returns information for the first hundred data frame analytics jobs.

Query parameters

  • allow_no_match boolean

    Specifies what to do when the request:

    1. Contains wildcard expressions and there are no data frame analytics jobs that match.
    2. Contains the _all string or no identifiers and there are no matches.
    3. Contains wildcard expressions and there are only partial matches.

    The default value returns an empty data_frame_analytics array when there are no matches and the subset of results when there are partial matches. If this parameter is false, the request returns a 404 status code when there are no matches or only partial matches.

  • from number

    Skips the specified number of data frame analytics jobs.

  • size number

    Specifies the maximum number of data frame analytics jobs to obtain.

  • exclude_generated boolean

    Indicates if certain fields should be removed from the configuration on retrieval. This allows the configuration to be in an acceptable format to be retrieved and then added to another cluster.

Responses

  • 200 application/json
    Hide response attributes Show response attributes object
    • count number Required
    • data_frame_analytics array[object] Required

      An array of data frame analytics job resources, which are sorted by the id value in ascending order.

      Hide data_frame_analytics attributes Show data_frame_analytics attributes object
      • allow_lazy_start boolean
      • analysis object Required
        Hide analysis attributes Show analysis attributes object
        • classification object
          Hide classification attributes Show classification attributes object
          • alpha number

            Advanced configuration option. Machine learning uses loss guided tree growing, which means that the decision trees grow where the regularized loss decreases most quickly. This parameter affects loss calculations by acting as a multiplier of the tree depth. Higher alpha values result in shallower trees and faster training times. By default, this value is calculated during hyperparameter optimization. It must be greater than or equal to zero.

          • dependent_variable string Required

            Defines which field of the document is to be predicted. It must match one of the fields in the index being used to train. If this field is missing from a document, then that document will not be used for training, but a prediction with the trained model will be generated for it. It is also known as continuous target variable. For classification analysis, the data type of the field must be numeric (integer, short, long, byte), categorical (ip or keyword), or boolean. There must be no more than 30 different values in this field. For regression analysis, the data type of the field must be numeric.

          • downsample_factor number

            Advanced configuration option. Controls the fraction of data that is used to compute the derivatives of the loss function for tree training. A small value results in the use of a small fraction of the data. If this value is set to be less than 1, accuracy typically improves. However, too small a value may result in poor convergence for the ensemble and so require more trees. By default, this value is calculated during hyperparameter optimization. It must be greater than zero and less than or equal to 1.

          • early_stopping_enabled boolean

            Advanced configuration option. Specifies whether the training process should finish if it is not finding any better performing models. If disabled, the training process can take significantly longer and the chance of finding a better performing model is unremarkable.

          • eta number

            Advanced configuration option. The shrinkage applied to the weights. Smaller values result in larger forests which have a better generalization error. However, larger forests cause slower training. By default, this value is calculated during hyperparameter optimization. It must be a value between 0.001 and 1.

          • eta_growth_rate_per_tree number

            Advanced configuration option. Specifies the rate at which eta increases for each new tree that is added to the forest. For example, a rate of 1.05 increases eta by 5% for each extra tree. By default, this value is calculated during hyperparameter optimization. It must be between 0.5 and 2.

          • feature_bag_fraction number

            Advanced configuration option. Defines the fraction of features that will be used when selecting a random bag for each candidate split. By default, this value is calculated during hyperparameter optimization.

          • feature_processors array[object]

            Advanced configuration option. A collection of feature preprocessors that modify one or more included fields. The analysis uses the resulting one or more features instead of the original document field. However, these features are ephemeral; they are not stored in the destination index. Multiple feature_processors entries can refer to the same document fields. Automatic categorical feature encoding still occurs for the fields that are unprocessed by a custom processor or that have categorical values. Use this property only if you want to override the automatic feature encoding of the specified fields.

          • gamma number

            Advanced configuration option. Regularization parameter to prevent overfitting on the training data set. Multiplies a linear penalty associated with the size of individual trees in the forest. A high gamma value causes training to prefer small trees. A small gamma value results in larger individual trees and slower training. By default, this value is calculated during hyperparameter optimization. It must be a nonnegative value.

          • lambda number

            Advanced configuration option. Regularization parameter to prevent overfitting on the training data set. Multiplies an L2 regularization term which applies to leaf weights of the individual trees in the forest. A high lambda value causes training to favor small leaf weights. This behavior makes the prediction function smoother at the expense of potentially not being able to capture relevant relationships between the features and the dependent variable. A small lambda value results in large individual trees and slower training. By default, this value is calculated during hyperparameter optimization. It must be a nonnegative value.

          • max_optimization_rounds_per_hyperparameter number

            Advanced configuration option. A multiplier responsible for determining the maximum number of hyperparameter optimization steps in the Bayesian optimization procedure. The maximum number of steps is determined based on the number of undefined hyperparameters times the maximum optimization rounds per hyperparameter. By default, this value is calculated during hyperparameter optimization.

          • max_trees number

            Advanced configuration option. Defines the maximum number of decision trees in the forest. The maximum value is 2000. By default, this value is calculated during hyperparameter optimization.

          • num_top_feature_importance_values number

            Advanced configuration option. Specifies the maximum number of feature importance values per document to return. By default, no feature importance calculation occurs.

          • prediction_field_name string

            Path to field or array of paths. Some API's support wildcards in the path to select multiple fields.

          • randomize_seed number

            Defines the seed for the random generator that is used to pick training data. By default, it is randomly generated. Set it to a specific value to use the same training data each time you start a job (assuming other related parameters such as source and analyzed_fields are the same).

          • soft_tree_depth_limit number

            Advanced configuration option. Machine learning uses loss guided tree growing, which means that the decision trees grow where the regularized loss decreases most quickly. This soft limit combines with the soft_tree_depth_tolerance to penalize trees that exceed the specified depth; the regularized loss increases quickly beyond this depth. By default, this value is calculated during hyperparameter optimization. It must be greater than or equal to 0.

          • soft_tree_depth_tolerance number

            Advanced configuration option. This option controls how quickly the regularized loss increases when the tree depth exceeds soft_tree_depth_limit. By default, this value is calculated during hyperparameter optimization. It must be greater than or equal to 0.01.

          • training_percent
          • class_assignment_objective string
          • num_top_classes number

            Defines the number of categories for which the predicted probabilities are reported. It must be non-negative or -1. If it is -1 or greater than the total number of categories, probabilities are reported for all categories; if you have a large number of categories, there could be a significant effect on the size of your destination index. NOTE: To use the AUC ROC evaluation method, num_top_classes must be set to -1 or a value greater than or equal to the total number of categories.

        • outlier_detection object
          Hide outlier_detection attributes Show outlier_detection attributes object
          • compute_feature_influence boolean

            Specifies whether the feature influence calculation is enabled.

          • feature_influence_threshold number

            The minimum outlier score that a document needs to have in order to calculate its feature influence score. Value range: 0-1.

          • method string

            The method that outlier detection uses. Available methods are lof, ldof, distance_kth_nn, distance_knn, and ensemble. The default value is ensemble, which means that outlier detection uses an ensemble of different methods and normalises and combines their individual outlier scores to obtain the overall outlier score.

          • n_neighbors number

            Defines the value for how many nearest neighbors each method of outlier detection uses to calculate its outlier score. When the value is not set, different values are used for different ensemble members. This default behavior helps improve the diversity in the ensemble; only override it if you are confident that the value you choose is appropriate for the data set.

          • outlier_fraction number

            The proportion of the data set that is assumed to be outlying prior to outlier detection. For example, 0.05 means it is assumed that 5% of values are real outliers and 95% are inliers.

          • standardization_enabled boolean

            If true, the following operation is performed on the columns before computing outlier scores: (x_i - mean(x_i)) / sd(x_i).

        • regression object
          Hide regression attributes Show regression attributes object
          • alpha number

            Advanced configuration option. Machine learning uses loss guided tree growing, which means that the decision trees grow where the regularized loss decreases most quickly. This parameter affects loss calculations by acting as a multiplier of the tree depth. Higher alpha values result in shallower trees and faster training times. By default, this value is calculated during hyperparameter optimization. It must be greater than or equal to zero.

          • dependent_variable string Required

            Defines which field of the document is to be predicted. It must match one of the fields in the index being used to train. If this field is missing from a document, then that document will not be used for training, but a prediction with the trained model will be generated for it. It is also known as continuous target variable. For classification analysis, the data type of the field must be numeric (integer, short, long, byte), categorical (ip or keyword), or boolean. There must be no more than 30 different values in this field. For regression analysis, the data type of the field must be numeric.

          • downsample_factor number

            Advanced configuration option. Controls the fraction of data that is used to compute the derivatives of the loss function for tree training. A small value results in the use of a small fraction of the data. If this value is set to be less than 1, accuracy typically improves. However, too small a value may result in poor convergence for the ensemble and so require more trees. By default, this value is calculated during hyperparameter optimization. It must be greater than zero and less than or equal to 1.

          • early_stopping_enabled boolean

            Advanced configuration option. Specifies whether the training process should finish if it is not finding any better performing models. If disabled, the training process can take significantly longer and the chance of finding a better performing model is unremarkable.

          • eta number

            Advanced configuration option. The shrinkage applied to the weights. Smaller values result in larger forests which have a better generalization error. However, larger forests cause slower training. By default, this value is calculated during hyperparameter optimization. It must be a value between 0.001 and 1.

          • eta_growth_rate_per_tree number

            Advanced configuration option. Specifies the rate at which eta increases for each new tree that is added to the forest. For example, a rate of 1.05 increases eta by 5% for each extra tree. By default, this value is calculated during hyperparameter optimization. It must be between 0.5 and 2.

          • feature_bag_fraction number

            Advanced configuration option. Defines the fraction of features that will be used when selecting a random bag for each candidate split. By default, this value is calculated during hyperparameter optimization.

          • feature_processors array[object]

            Advanced configuration option. A collection of feature preprocessors that modify one or more included fields. The analysis uses the resulting one or more features instead of the original document field. However, these features are ephemeral; they are not stored in the destination index. Multiple feature_processors entries can refer to the same document fields. Automatic categorical feature encoding still occurs for the fields that are unprocessed by a custom processor or that have categorical values. Use this property only if you want to override the automatic feature encoding of the specified fields.

            Advanced configuration option. A multiplier responsible for determining the maximum number of hyperparameter optimization steps in the Bayesian optimization procedure. The maximum number of steps is determined based on the number of undefined hyperparameters times the maximum optimization rounds per hyperparameter. By default, this value is calculated during hyperparameter optimization.

          • max_trees number

          • num_top_feature_importance_values number

            Advanced configuration option. Specifies the maximum number of feature importance values per document to return. By default, no feature importance calculation occurs.

          • prediction_field_name string

            Path to field or array of paths. Some API's support wildcards in the path to select multiple fields.

          • randomize_seed number

            Defines the seed for the random generator that is used to pick training data. By default, it is randomly generated. Set it to a specific value to use the same training data each time you start a job (assuming other related parameters such as source and analyzed_fields are the same).

          • soft_tree_depth_limit number

            Advanced configuration option. Machine learning uses loss guided tree growing, which means that the decision trees grow where the regularized loss decreases most quickly. This soft limit combines with the soft_tree_depth_tolerance to penalize trees that exceed the specified depth; the regularized loss increases quickly beyond this depth. By default, this value is calculated during hyperparameter optimization. It must be greater than or equal to 0.

          • soft_tree_depth_tolerance number

Authenticate SAML Added in 7.5.0

POST /_security/saml/authenticate
Api key auth Basic auth Bearer auth

Submit a SAML response message to Elasticsearch for consumption.

NOTE: This API is intended for use by custom web applications other than Kibana. If you are using Kibana, refer to the documentation for configuring SAML single-sign-on on the Elastic Stack.

The SAML message that is submitted can be:

  • A response to a SAML authentication request that was previously created using the SAML prepare authentication API.
  • An unsolicited SAML message in the case of an IdP-initiated single sign-on (SSO) flow.

In either case, the SAML message needs to be a base64 encoded XML document with a root element of <Response>.

After successful validation, Elasticsearch responds with an Elasticsearch internal access token and refresh token that can be subsequently used for authentication. This API endpoint essentially exchanges SAML responses that indicate successful authentication in the IdP for Elasticsearch access and refresh tokens, which can be used for authentication against Elasticsearch.

        • config object
          Hide config attributes Show config attributes object
          • ignore_unavailable boolean

            If false, the snapshot fails if any data stream or index in indices is missing or closed. If true, the snapshot ignores missing or closed data streams and indices.

          • indices string | array[string]
          • include_global_state boolean

            If true, the current global state is included in the snapshot.

          • feature_states array[string]

            A list of feature states to be included in this snapshot. A list of features available for inclusion in the snapshot and their descriptions be can be retrieved using the get features API. Each feature state includes one or more system indices containing data necessary for the function of that feature. Providing an empty array will include no feature states in the snapshot, regardless of the value of include_global_state. By default, all available feature states will be included in the snapshot if include_global_state is true, or no feature states if include_global_state is false.

        • repository string Required
        • retention object
          Hide retention attributes Show retention attributes object
          • expire_after string Required

            A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

          • max_count number Required

            Maximum number of snapshots to retain, even if the snapshots have not yet expired. If the number of snapshots in the repository exceeds this limit, the policy retains the most recent snapshots and deletes older snapshots.

          • min_count number Required

            Minimum number of snapshots to retain, even if the snapshots have expired.

        • schedule string Required
