Get the autoscaling capacity Added in 7.11.0

GET /_autoscaling/capacity

NOTE: This feature is designed for indirect use by Elasticsearch Service, Elastic Cloud Enterprise, and Elastic Cloud on Kubernetes. Direct use is not supported.

This API gets the current autoscaling capacity based on the configured autoscaling policy. It will return information to size the cluster appropriately to the current workload.

The required_capacity is calculated as the maximum of the required_capacity result of all individual deciders that are enabled for the policy.

The operator should verify that the current_nodes match the operator’s knowledge of the cluster to avoid making autoscaling decisions based on stale or incomplete information.

The response contains decider-specific information you can use to diagnose how and why autoscaling determined a certain capacity was required. This information is provided for diagnosis only. Do not use this information to make autoscaling decisions.

Reset the features Technical preview

POST /_features/_reset

Clear all of the state information stored in system indices by Elasticsearch features, including the security and machine learning indices.

WARNING: Intended for development and testing use only. Do not reset features on a production cluster.

Return a cluster to the same state as a new installation by resetting the feature state for all Elasticsearch features. This deletes all state information stored in system indices.

The response code is HTTP 200 if the state is successfully reset for all features. It is HTTP 500 if the reset operation failed for any feature.

Note that select features might provide a way to reset particular system indices. Using this API resets all features, both those that are built-in and implemented as plugins.

To list the features that will be affected, use the get features API.

IMPORTANT: The features installed on the node you submit this request to are the features that will be reset. Run on the master node if you have any doubts about which plugins are installed on individual nodes.

Query parameters

  • Period to wait for a connection to the master node.

    Values are -1 or 0.

Run multiple Fleet searches Technical preview

GET /_fleet/_fleet_msearch

Run several Fleet searches with a single API request. The API follows the same structure as the multi search API. However, similar to the Fleet search API, it supports the wait_for_checkpoints parameter.

Query parameters

  • 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. For example, a request targeting foo*,bar* returns an error if an index starts with foo but no index starts with bar.

  • If true, network roundtrips between the coordinating node and remote clusters are minimized for cross-cluster search requests.

  • expand_wildcards string | array[string]

    Type of index that wildcard expressions can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams.

    Supported values include:

    • all: Match any data stream or index, including hidden ones.
    • open: Match open, non-hidden indices. Also matches any non-hidden data stream.
    • closed: Match closed, non-hidden indices. Also matches any non-hidden data stream. Data streams cannot be closed.
    • hidden: Match hidden data streams and hidden indices. Must be combined with open, closed, or both.
    • none: Wildcard expressions are not accepted.

    Values are all, open, closed, hidden, or none.

  • If true, concrete, expanded or aliased indices are ignored when frozen.

  • If true, missing or closed indices are not included in the response.

  • Maximum number of concurrent searches the multi search API can execute.

  • Maximum number of concurrent shard requests that each sub-search request executes per node.

  • Defines a threshold that enforces a pre-filter roundtrip to prefilter search shards based on query rewriting if the number of shards the search request expands to exceeds the threshold. This filter roundtrip can limit the number of shards significantly if for instance a shard can not match any documents based on its rewrite method i.e., if date filters are mandatory to match but the shard bounds and the query are disjoint.

  • Indicates whether global term and document frequencies should be used when scoring returned documents.

    Supported values include:

    • query_then_fetch: Documents are scored using local term and document frequencies for the shard. This is usually faster but less accurate.
    • dfs_query_then_fetch: Documents are scored using global term and document frequencies across all shards. This is usually slower but more accurate.

    Values are query_then_fetch or dfs_query_then_fetch.

  • If true, hits.total are returned as an integer in the response. Defaults to false, which returns an object.

  • typed_keys boolean

    Specifies whether aggregation and suggester names should be prefixed by their respective types in the response.

  • A comma separated list of checkpoints. When configured, the search API will only be executed on a shard after the relevant checkpoint has become visible for search. Defaults to an empty list which will cause Elasticsearch to immediately execute the search.

  • If true, returns partial results if there are shard request timeouts or shard failures. If false, returns an error with no partial results. Defaults to the configured cluster setting search.default_allow_partial_results, which is true by default.

Add an index block Added in 7.9.0

PUT /{index}/_block/{block}

Add an index block to an index. Index blocks limit the operations allowed on an index by blocking specific operation types.

Path parameters

  • index string Required

    A comma-separated list or wildcard expression of index names used to limit the request. By default, you must explicitly name the indices you are adding blocks to. To allow the adding of blocks to indices with _all, *, or other wildcard expressions, change the action.destructive_requires_name setting to false. You can update this setting in the elasticsearch.yml file or by using the cluster update settings API.

  • block string Required

    The block type to add to the index.

    Supported values include:

    • metadata: Disable metadata changes, such as closing the index.
    • read: Disable read operations.
    • read_only: Disable write operations and metadata changes.
    • write: Disable write operations. However, metadata changes are still allowed.

    Values are metadata, read, read_only, or write.

Query parameters

  • 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. For example, a request targeting foo*,bar* returns an error if an index starts with foo but no index starts with bar.

  • expand_wildcards string | array[string]

    The 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. It supports comma-separated values, such as open,hidden.

    Supported values include:

    • all: Match any data stream or index, including hidden ones.

    • closed: Match closed, non-hidden indices. Also matches any non-hidden data stream. Data streams cannot be closed.
    • hidden: Match hidden data streams and hidden indices. Must be combined with open, closed, or both.
    • none: Wildcard expressions are not accepted.

    Values are all, open, closed, hidden, or none.

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

  • The period to wait for the master node. If the master node is not available before the timeout expires, the request fails and returns an error. It can also be set to -1 to indicate that the request should never timeout.

    Values are -1 or 0.

  • timeout string

    The period to wait for a response from all relevant nodes in the cluster after updating the cluster metadata. If no response is received before the timeout expires, the cluster metadata update still applies but the response will indicate that it was not completely acknowledged. It can also be set to -1 to indicate that the request should never timeout.

    Values are -1 or 0.

Update index settings

PUT /_settings

Changes dynamic index settings in real time. For data streams, index setting changes are applied to all backing indices by default.

To revert a setting to the default value, use a null value. The list of per-index settings that can be updated dynamically on live indices can be found in index module documentation. To preserve existing settings from being updated, set the preserve_existing parameter to true.

NOTE: You can only define new analyzers on closed indices. To add an analyzer, you must close the index, define the analyzer, and reopen the index. You cannot close the write index of a data stream. To update the analyzer for a data stream's write index and future backing indices, update the analyzer in the index template used by the stream. Then roll over the data stream to apply the new analyzer to the stream's write index and future backing indices. This affects searches and any new data added to the stream after the rollover. However, it does not affect the data stream's backing indices or their existing data. To change the analyzer for existing backing indices, you must create a new data stream and reindex your data into it.

    • If specified, this is the timestamp used to calculate the index age for its phase transitions. Use this setting if you create a new index that contains old data and want to use the original creation date to calculate the index age. Specified as a Unix epoch value in milliseconds.

    • Set to true to parse the origination date from the index name. This origination date is used to calculate the index age for its phase transitions. The index name must match the pattern .*-{date_format}-\d+, where the date_format is yyyy.MM.dd and the trailing digits are optional. An index that was rolled over would normally match the full format, for example logs-2016.10.31-000002). If the index name doesn’t match the pattern, index creation fails.

    • step object
      Hide step attribute Show step attribute object
      • 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.

    • The index alias to update when the index rolls over. Specify when using a policy that contains a rollover action. When the index rolls over, the alias is updated to reflect that the index is no longer the write index. For more information about rolling indices, see Rollover.

    • prefer_ilm boolean | string

      Preference for the system that manages a data stream backing index (preferring ILM when both ILM and DLM are applicable for an index).

    • coerce boolean
    • Hide total_fields attributes Show total_fields attributes object
      • limit number | string

        The maximum number of fields in an index. Field and object mappings, as well as field aliases count towards this limit. The limit is in place to prevent mappings and searches from becoming too large. Higher values can lead to performance degradations and memory issues, especially in clusters with a high load or few resources.

      • ignore_dynamic_beyond_limit boolean | string

        This setting determines what happens when a dynamically mapped field would exceed the total fields limit. When set to false (the default), the index request of the document that tries to add a dynamic field to the mapping will fail with the message Limit of total fields [X] has been exceeded. When set to true, the index request will not fail. Instead, fields that would exceed the limit are not added to the mapping, similar to dynamic: false. The fields that were not added to the mapping will be added to the _ignored field.

    • depth object
      Hide depth attribute Show depth attribute object
      • limit number

        The maximum depth for a field, which is measured as the number of inner objects. For instance, if all fields are defined at the root object level, then the depth is 1. If there is one object mapping, then the depth is 2, etc.

    • Hide nested_fields attribute Show nested_fields attribute object
      • limit number

        The maximum number of distinct nested mappings in an index. The nested type should only be used in special cases, when arrays of objects need to be queried independently of each other. To safeguard against poorly designed mappings, this setting limits the number of unique nested types per index.

    • Hide nested_objects attribute Show nested_objects attribute object
      • limit number

        The maximum number of nested JSON objects that a single document can contain across all nested types. This limit helps to prevent out of memory errors when a document contains too many nested objects.

    • Hide field_name_length attribute Show field_name_length attribute object
      • limit number

        Setting for the maximum length of a field name. This setting isn’t really something that addresses mappings explosion but might still be useful if you want to limit the field length. It usually shouldn’t be necessary to set this setting. The default is okay unless a user starts to add a huge number of fields with really long names. Default is Long.MAX_VALUE (no limit).

      • limit number

        Number of outstanding bytes that may be consumed by indexing requests. When this limit is reached or exceeded, the node will reject new coordinating and primary operations. When replica operations consume 1.5x this limit, the node will reject new replica operations. Defaults to 10% of the heap.

    • allow_mmap boolean

      You can restrict the use of the mmapfs and the related hybridfs store type via the setting node.store.allow_mmap. This is a boolean setting indicating whether or not memory-mapping is allowed. The default is to allow it. This setting is useful, for example, if you are in an environment where you can not control the ability to create a lot of memory maps so you need disable the ability to use memory-mapping.

Shrink an index Added in 5.0.0

POST /{index}/_shrink/{target}

Shrink an index into a new index with fewer primary shards.

Before you can shrink an index:

  • The index must be read-only.
  • A copy of every shard in the index must reside on the same node.
  • The index must have a green health status.

To make shard allocation easier, we recommend you also remove the index's replica shards. You can later re-add replica shards as part of the shrink operation.

The requested number of primary shards in the target index must be a factor of the number of shards in the source index. For example an index with 8 primary shards can be shrunk into 4, 2 or 1 primary shards or an index with 15 primary shards can be shrunk into 5, 3 or 1. If the number of shards in the index is a prime number it can only be shrunk into a single primary shard Before shrinking, a (primary or replica) copy of every shard in the index must be present on the same node.

The current write index on a data stream cannot be shrunk. In order to shrink the current write index, the data stream must first be rolled over so that a new write index is created and then the previous write index can be shrunk.

A shrink operation:

  • Creates a new target index with the same definition as the source index, but with a smaller number of primary shards.
  • Hard-links segments from the source index into the target index. If the file system does not support hard-linking, then all segments are copied into the new index, which is a much more time consuming process. Also if using multiple data paths, shards on different data paths require a full copy of segment files if they are not on the same disk since hardlinks do not work across disks.
  • Recovers the target index as though it were a closed index which had just been re-opened. Recovers shards to the .routing.allocation.initial_recovery._id index setting.

IMPORTANT: Indices can only be shrunk if they satisfy the following requirements:

  • The target index must not exist.
  • The source index must have more primary shards than the target index.
  • The number of primary shards in the target index must be a factor of the number of primary shards in the source index. The source index must have more primary shards than the target index.
  • The index must not contain more than 2,147,483,519 documents in total across all shards that will be shrunk into a single shard on the target index as this is the maximum number of docs that can fit into a single shard.
  • The node handling the shrink process must have sufficient free disk space to accommodate a second copy of the existing index.

Path parameters

  • index string Required

    Name of the source index to shrink.

  • target string Required

    Name of the target index to create.

Query parameters

  • 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.

    Values are -1 or 0.

  • timeout string

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

    Values are -1 or 0.

  • wait_for_active_shards number | string

          An array of strings that defines the fields that will be included in the analysis.

      • query object

        The Elasticsearch query domain-specific language (DSL). This value corresponds to the query object in an Elasticsearch search POST body. All the options that are supported by Elasticsearch can be used, as this object is passed verbatim to Elasticsearch. By default, this property has the following value: {"match_all": {}}.

        Query DSL
    • analysis object Required
      Hide analysis attributes Show analysis attributes 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.

        • 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.

        • 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.

        • 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.

        • 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.

          Hide feature_processors attributes Show feature_processors attributes object
        • 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.

        • 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.

        • 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.

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

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

        • 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).

        • 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.

        • 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.

        • 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.

      • Hide outlier_detection attributes Show outlier_detection attributes object
        • Specifies whether the feature influence calculation is enabled.

        • 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.

        • 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.

        • 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.

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

      • 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.

    A comma-separated list of data streams, indices, and index aliases used to limit the request. Wildcard (*) expressions are supported. To target all data streams and indices in a cluster, omit this parameter or use _all or *.

Query parameters

  • 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. For example, a request targeting foo*,bar* returns an error if an index starts with foo but no index starts with bar.

  • expand_wildcards string | array[string]

    Whether to expand wildcard expression to concrete indices that are open, closed or both.

    Supported values include:

    • all: Match any data stream or index, including hidden ones.
    • open: Match open, non-hidden indices. Also matches any non-hidden data stream.
    • closed: Match closed, non-hidden indices. Also matches any non-hidden data stream. Data streams cannot be closed.
    • hidden: Match hidden data streams and hidden indices. Must be combined with open, closed, or both.
    • none: Wildcard expressions are not accepted.

    Values are all, open, closed, hidden, or none.

  • If true, missing or closed indices are not included in the response.

Get transforms Added in 7.5.0

GET /_transform

Get configuration information for transforms.

Query parameters

  • Specifies what to do when the request:

    1. Contains wildcard expressions and there are no transforms that match.
    2. Contains the _all string or no identifiers and there are no matches.

  • from number

    Skips the specified number of transforms.

  • size number

    Specifies the maximum number of transforms to obtain.

  • Excludes fields that were automatically added when creating the transform. 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
    • transforms array[object] Required
      Hide transforms attributes Show transforms attributes object
      • Hide authorization attributes Show authorization attributes object

          • id string Required

            The identifier for the API key.

          • name string Required

            The name of the API key.

        • roles array[string]

          If a user ID was used for the most recent update to the transform, its roles at the time of the update are listed in the response.

        • If a service account was used for the most recent update to the transform, the account name is listed in the response.

      • Time unit for milliseconds

      • create_time_string string | number

        A date and time, either as a string whose format can depend on the context (defaulting to ISO 8601), or a number of milliseconds since the Epoch. Elasticsearch accepts both as input, but will generally output a string representation.

      • Free text description of the transform.

      • dest object Required
        Hide dest attributes Show dest attributes object
      • 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.

      • latest object
        Hide latest attributes Show latest attributes object
        • sort string Required

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

      • settings object
        Hide settings attributes Show settings attributes object
        • Specifies whether the transform checkpoint ranges should be optimized for performance. Such optimization can align checkpoint ranges with the date histogram interval when date histogram is specified as a group source in the transform config. As a result, less document updates in the destination index will be performed thus improving overall performance.

        • Defines if dates in the ouput should be written as ISO formatted string or as millis since epoch. epoch_millis was the default for transforms created before version 7.11. For compatible output set this value to true.

        • Specifies whether the transform should deduce the destination index mappings from the transform configuration.

        • Specifies a limit on the number of input documents per second. This setting throttles the transform by adding a wait time between search requests. The default value is null, which disables throttling.

        • Defines the initial page size to use for the composite aggregation for each checkpoint. If circuit breaker exceptions occur, the page size is dynamically adjusted to a lower value. The minimum value is 10 and the maximum is 65,536.

        • unattended boolean

          If true, the transform runs in unattended mode. In unattended mode, the transform retries indefinitely in case of an error which means the transform never fails. Setting the number of retries other than infinite fails in validation.

Acknowledge a watch

POST /_watcher/watch/{watch_id}/_ack/{action_id}

Acknowledging a watch enables you to manually throttle the execution of the watch's actions.

The acknowledgement state of an action is stored in the status.actions.<id>.ack.state structure.

IMPORTANT: If the specified watch is currently being executed, this API will return an error The reason for this behavior is to prevent overwriting the watch status from a watch execution.

Acknowledging an action throttles further executions of that action until its ack.state is reset to awaits_successful_execution. This happens when the condition of the watch is not met (the condition evaluates to false).

Path parameters

  • watch_id string Required

    The watch identifier.

  • action_id string | array[string] Required

    A comma-separated list of the action identifiers to acknowledge. If you omit this parameter, all of the actions of the watch are acknowledged.

          The largest size of the execution thread pool, which indicates the largest number of concurrent running watches.

        • queue_size number Required

          The number of watches that were triggered and are currently queued.

      • queued_watches array[object]

        Watcher moderates the execution of watches such that their execution won't put too much pressure on the node and its resources. If too many watches trigger concurrently and there isn't enough capacity to run them all, some of the watches are queued, waiting for the current running watches to finish.s The queued watches metric gives insight on these queued watches.

        To include this metric, the metric option should include queued_watches or _all.
