http://api.example.comElasticsearch provides REST APIs that are used by the UI components and can be called directly to configure and access Elasticsearch features.
This documentation is derived from the main branch of the elasticsearch-specification repository. It is provided under license Attribution-NonCommercial-NoDerivatives 4.0 International.
This documentation contains work-in-progress information for future Elastic Stack releases.
Last update on Jul 23, 2025.
This API is provided under license Apache 2.0.
The API accepts 3 different authentication methods:
Elasticsearch APIs support key-based authentication. You must create an API key and use the encoded value in the request header. For example:
curl -X GET "${ES_URL}/_cat/indices?v=true" \
-H "Authorization: ApiKey ${API_KEY}"
To get API keys, use the /_security/api_key APIs.
Elasticsearch APIs support the use of bearer tokens in the Authorization HTTP header to authenticate with the API.
For examples, refer to Token-based authentication services

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.

}The compact and aligned text (CAT) APIs aim are intended only for human consumption using the Kibana console or command line. They are not intended for use by applications. For application consumption, it's recommend to use a corresponding JSON API.
All the cat commands accept a query string parameter help to see all the headers and info they provide, and the /_cat command alone lists all the available commands.
All methods and paths for this operation:
Get the cluster's index aliases, including filter and routing information. This API does not return data stream aliases.
IMPORTANT: CAT APIs are only intended for human consumption using the command line or the Kibana console. They are not intended for use by applications. For application consumption, use the aliases API.

List of columns to appear in the response. Supports simple wildcards.
List of columns that determine how the table should be sorted.
Sorting defaults to ascending and can be changed by setting :asc
or :desc as a suffix to the column name.
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.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.
The period to wait for a connection to the master node.
If the master node is not available before the timeout expires, the request fails and returns an error.
To indicated that the request should never timeout, you can set it to -1.
Values are -1 or 0.

]IMPORTANT: CAT APIs are only intended for human consumption using the command line or Kibana console.
They are not intended for use by applications. For application consumption, use the cluster health API.
This API is often used to check malfunctioning clusters.
To help you track cluster health alongside log files and alerting systems, the API returns timestamps in two formats:
HH:MM:SS, which is human-readable but includes no date information;
Unix epoch time, which is machine-sortable and includes date information.
The latter format is useful for cluster recoveries that take multiple days.
You can use the cat health API to verify cluster health across multiple nodes.
You also can use the API to track the recovery of a large cluster over a longer period of time.
monitorThe unit used to display time values.
Values are nanos, micros, ms, s, m, h, or d.
If true, returns HH:MM:SS and Unix epoch timestamps.

are still processed because it is possible that not all fields are missing.data.out_of_order_timestamps (or doot, dataOutOfOrderTimestamps): The number of input documents that have a timestamp chronologically
preceding the start of the current anomaly detection bucket offset by the
latency window. This information is applicable only when you provide data
to the anomaly detection job by using the post data API. These out of order
documents are discarded, since jobs require time series data to be in
ascending chronological order.data.processed_fields (or dpf, dataProcessedFields): The total number of fields in all the documents that have been processed by

is cumulative for all detectors in the job.model.bytes (or mb, modelBytes): The number of bytes of memory used by the models. This is the maximum value
since the last time the model was persisted. If the job is closed, this
value indicates the latest size.model.bytes_exceeded (or mbe, modelBytesExceeded): The number of bytes over the high limit for memory usage at the last
allocation failure.model.categorization_status (or mcs, modelCategorizationStatus): The status of categorization for the job: ok or warn. If ok,
categorization is performing acceptably well (or not being used at all). If
warn, categorization is detecting a distribution of categories that
suggests the input data is inappropriate for categorization. Problems could
be that there is only one category, more than 90% of categories are rare,
the number of categories is greater than 50% of the number of categorized
documents, there are no frequently matched categories, or more than 50% of
categories are dead.model.categorized_doc_count (or mcdc, modelCategorizedDocCount): The number of documents that have had a field categorized.model.dead_category_count (or mdcc, modelDeadCategoryCount): The number of categories created by categorization that will never be
assigned again because another category’s definition makes it a superset of
the dead category. Dead categories are a side effect of the way
categorization has no prior training.model.failed_category_count (or mdcc, modelFailedCategoryCount): The number of times that categorization wanted to create a new category but
couldn’t because the job had hit its model memory limit. This count does
not track which specific categories failed to be created. Therefore, you
cannot use this value to determine the number of unique categories that
were missed.model.frequent_category_count (or mfcc, modelFrequentCategoryCount): The number of categories that match more than 1% of categorized documents.model.log_time (or mlt, modelLogTime): The timestamp when the model stats were gathered, according to server time.model.memory_limit (or mml, modelMemoryLimit): The timestamp when the model stats were gathered, according to server time.model.memory_status (or mms, modelMemoryStatus): The status of the mathematical models: ok, soft_limit, or hard_limit.
If ok, the models stayed below the configured value. If soft_limit, the
models used more than 60% of the configured memory limit and older unused
models will be pruned to free up space. Additionally, in categorization jobs
no further category examples will be stored. If hard_limit, the models
used more space than the configured memory limit. As a result, not all
incoming data was processed.model.over_fields (or mof, modelOverFields): The number of over field values that were analyzed by the models. This
value is cumulative for all detectors in the job.model.partition_fields (or mpf, modelPartitionFields): The number of partition field values that were analyzed by the models. This
value is cumulative for all detectors in the job.model.rare_category_count (or mrcc, modelRareCategoryCount): The number of categories that match just one categorized document.model.timestamp (or mt, modelTimestamp): The timestamp of the last record when the model stats were gathered.model.total_category_count (or mtcc, modelTotalCategoryCount): The number of categories created by categorization.node.address (or na, nodeAddress): The network address of the node that runs the job.

for open jobs.opened_time (or ot): For open jobs only, the elapsed time for which the job has been open.state (or s): The status of the anomaly detection job: closed, closing, failed,
opened, or opening. If closed, the job finished successfully with its
model state persisted. The job must be opened before it can accept further
data. If closing, the job close action is in progress and has not yet
completed. A closing job cannot accept further data. If failed, the job
did not finish successfully due to an error. This situation can occur due
to invalid input data, a fatal error occurring during the analysis, or an
external interaction such as the process being killed by the Linux out of
memory (OOM) killer. If the job had irrevocably failed, it must be force
closed and then deleted. If the datafeed can be corrected, the job can be
closed and then re-opened. If opened, the job is available to receive and
process data. If opening, the job open action is in progress and has not
yet completed.Comma-separated list of column names or column aliases used to sort the response.

processed due to insufficient model memory.model.by_fields (or mbf, modelByFields): The number of by field values that were analyzed by the models. This value
is cumulative for all detectors in the job.model.bytes (or mb, modelBytes): The number of bytes of memory used by the models. This is the maximum value
since the last time the model was persisted. If the job is closed, this
value indicates the latest size.model.bytes_exceeded (or mbe, modelBytesExceeded): The number of bytes over the high limit for memory usage at the last
allocation failure.model.categorization_status (or mcs, modelCategorizationStatus): The status of categorization for the job: ok or warn. If ok,
categorization is performing acceptably well (or not being used at all). If
warn, categorization is detecting a distribution of categories that
suggests the input data is inappropriate for categorization. Problems could
be that there is only one category, more than 90% of categories are rare,
the number of categories is greater than 50% of the number of categorized
documents, there are no frequently matched categories, or more than 50% of
categories are dead.model.categorized_doc_count (or mcdc, modelCategorizedDocCount): The number of documents that have had a field categorized.model.dead_category_count (or mdcc, modelDeadCategoryCount): The number of categories created by categorization that will never be
assigned again because another category’s definition makes it a superset of
the dead category. Dead categories are a side effect of the way
categorization has no prior training.model.failed_category_count (or mdcc, modelFailedCategoryCount): The number of times that categorization wanted to create a new category but
couldn’t because the job had hit its model memory limit. This count does
not track which specific categories failed to be created. Therefore, you
cannot use this value to determine the number of unique categories that
were missed.model.frequent_category_count (or mfcc, modelFrequentCategoryCount): The number of categories that match more than 1% of categorized documents.model.log_time (or mlt, modelLogTime): The timestamp when the model stats were gathered, according to server time.model.memory_limit (or mml, modelMemoryLimit): The timestamp when the model stats were gathered, according to server time.model.memory_status (or mms, modelMemoryStatus): The status of the mathematical models: ok, soft_limit, or hard_limit.
If ok, the models stayed below the configured value. If soft_limit, the
models used more than 60% of the configured memory limit and older unused
models will be pruned to free up space. Additionally, in categorization jobs
no further category examples will be stored. If hard_limit, the models
used more space than the configured memory limit. As a result, not all
incoming data was processed.model.over_fields (or mof, modelOverFields): The number of over field values that were analyzed by the models. This
value is cumulative for all detectors in the job.model.partition_fields (or mpf, modelPartitionFields): The number of partition field values that were analyzed by the models. This
value is cumulative for all detectors in the job.model.rare_category_count (or mrcc, modelRareCategoryCount): The number of categories that match just one categorized document.model.timestamp (or mt, modelTimestamp): The timestamp of the last record when the model stats were gathered.model.total_category_count (or mtcc, modelTotalCategoryCount): The number of categories created by categorization.node.address (or na, nodeAddress): The network address of the node that runs the job.

available only for open jobs.node.id (or ni, nodeId): The unique identifier of the node that runs the job. This information is
available only for open jobs.node.name (or nn, nodeName): The name of the node that runs the job. This information is available only
for open jobs.opened_time (or ot): For open jobs only, the elapsed time for which the job has been open.state (or s): The status of the anomaly detection job: closed, closing, failed,
opened, or opening. If closed, the job finished successfully with its
model state persisted. The job must be opened before it can accept further
data. If closing, the job close action is in progress and has not yet
completed. A closing job cannot accept further data. If failed, the job
did not finish successfully due to an error. This situation can occur due
to invalid input data, a fatal error occurring during the analysis, or an
external interaction such as the process being killed by the Linux out of
memory (OOM) killer. If the job had irrevocably failed, it must be force
closed and then deleted. If the datafeed can be corrected, the job can be
closed and then re-opened. If opened, the job is available to receive and
process data. If opening, the job open action is in progress and has not
yet completed.The unit used to display time values.
Values are nanos, micros, ms, s, m, h, or d.

]All methods and paths for this operation:
Get information about ongoing and completed shard recoveries. Shard recovery is the process of initializing a shard copy, such as restoring a primary shard from a snapshot or syncing a replica shard from a primary shard. When a shard recovery completes, the recovered shard is available for search and indexing. For data streams, the API returns information about the stream’s backing indices. IMPORTANT: cat APIs are only intended for human consumption using the command line or Kibana console. They are not intended for use by applications. For application consumption, use the index recovery API.

index (or i, idx): The name of the index.shard (or s, sh): The name of the shard.prirep (or p, pr, primaryOrReplica): The shard type. Returned values are 'primary' or 'replica'.ip: IP address of the segment’s shard, such as '127.0.1.1'.segment: The name of the segment, such as '_0'. The segment name is derived from the segment generation and used internally to create file names in the directory of the shard.generation: Generation number, such as '0'. Elasticsearch increments this generation number for each segment written. Elasticsearch then uses this number to derive the segment name.docs.count: The number of documents as reported by Lucene. This excludes deleted documents and counts any nested documents separately from their parents. It also excludes documents which were indexed recently and do not yet belong to a segment.docs.deleted: The number of deleted documents as reported by Lucene, which may be higher or lower than the number of delete operations you have performed. This number excludes deletes that were performed recently and do not yet belong to a segment. Deleted documents are cleaned up by the automatic merge process if it makes sense to do so. Also, Elasticsearch creates extra deleted documents to internally track the recent history of operations on a shard.size: The disk space used by the segment, such as '50kb'.size.memory: The bytes of segment data stored in memory for efficient search, such as '1264'. A value of '-1' indicates Elasticsearch was unable to compute this number.committed: If 'true', the segments is synced to disk. Segments that are synced can survive a hard reboot. If 'false', the data from uncommitted segments is also stored in the transaction log so that Elasticsearch is able to replay changes on the next start.searchable: If 'true', the segment is searchable. If 'false', the segment has most likely been written to disk but needs a refresh to be searchable.version: The version of Lucene used to write the segment.compound: If 'true', the segment is stored in a compound file. This means Lucene merged all files from the segment in a single file to save file descriptors.id: The ID of the node, such as 'k0zy'.Values are index, i, idx, shard, s, sh, prirep, p, pr, primaryOrReplica, ip, segment, generation, docs.count, docs.deleted, size, size.memory, committed, searchable, version, compound, or id.

Get explanations for shard allocations in the cluster. This API accepts the current_node, index, primary and shard parameters in the request body or in query parameters, but not in both at the same time. 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. Refer to the linked documentation for examples of how to troubleshoot allocation issues using this API.
The name of the index that you would like an explanation for.
An identifier for the shard that you would like an explanation for.
If true, returns an explanation for the primary shard for the specified shard ID.

}Update the cluster voting config exclusions by node IDs or node names. By default, if there are more than three master-eligible nodes in the cluster and you remove fewer than half of the master-eligible nodes in the cluster at once, the voting configuration automatically shrinks. If you want to shrink the voting configuration to contain fewer than three nodes or to remove half or more of the master-eligible nodes in the cluster at once, use this API to remove departing nodes from the voting configuration manually. The API adds an entry for each specified node to the cluster’s voting configuration exclusions list. It then waits until the cluster has reconfigured its voting configuration to exclude the specified nodes.
Clusters should have no voting configuration exclusions in normal operation.
Once the excluded nodes have stopped, clear the voting configuration exclusions with DELETE /_cluster/voting_config_exclusions.
This API waits for the nodes to be fully removed from the cluster before it returns.
If your cluster has voting configuration exclusions for nodes that you no longer intend to remove, use DELETE /_cluster/voting_config_exclusions?wait_for_removal=false to clear the voting configuration exclusions without waiting for the nodes to leave the cluster.
A response to POST /_cluster/voting_config_exclusions with an HTTP status code of 200 OK guarantees that the node has been removed from the voting configuration and will not be reinstated until the voting configuration exclusions are cleared by calling DELETE /_cluster/voting_config_exclusions.
If the call to POST /_cluster/voting_config_exclusions fails or returns a response with an HTTP status code other than 200 OK then the node may not have been removed from the voting configuration.
In that case, you may safely retry the call.
NOTE: Voting exclusions are required only when you remove at least half of the master-eligible nodes from a cluster in a short time period. They are not required when removing master-ineligible nodes or when removing fewer than half of the master-eligible nodes.

You can also configure dynamic settings locally on an unstarted or shut down node in elasticsearch.yml.
Updates made with this API can be persistent, which apply across cluster restarts, or transient, which reset after a cluster restart. You can also reset transient or persistent settings by assigning them a null value.
If you configure the same setting using multiple methods, Elasticsearch applies the settings in following order of precedence: 1) Transient setting; 2) Persistent setting; 3) elasticsearch.yml setting; 4) Default setting value.
For example, you can apply a transient setting to override a persistent setting or elasticsearch.yml setting.
However, a change to an elasticsearch.yml setting will not override a defined transient or persistent setting.
TIP: In Elastic Cloud, use the user settings feature to configure all cluster settings. This method automatically rejects unsafe settings that could break your cluster.
If you run Elasticsearch on your own hardware, use this API to configure dynamic cluster settings.
Only use elasticsearch.yml for static cluster settings and node settings.
The API doesn’t require a restart and ensures a setting’s value is the same on all nodes.
WARNING: Transient cluster settings are no longer recommended. Use persistent cluster settings instead. If a cluster becomes unstable, transient settings can clear unexpectedly, resulting in a potentially undesired cluster configuration.
Return settings in flat format (default: false)

You can also use the API to get the health status of only specified data streams and indices. For data streams, the API retrieves the health status of the stream’s backing indices.
The cluster health status is: green, yellow or red. On the shard level, a red status indicates that the specific shard is not allocated in the cluster. Yellow means that the primary shard is allocated but replicas are not. Green means that all shards are allocated. The index level status is controlled by the worst shard status.
One of the main benefits of the API is the ability to wait until the cluster reaches a certain high watermark health level. The cluster status is controlled by the worst index status.

Get information about cluster-level changes (such as create index, update mapping, allocate or fail shard) that have not yet taken effect.
NOTE: This API returns a list of any pending updates to the cluster state. These are distinct from the tasks reported by the task management API which include periodic tasks and tasks initiated by the user, such as node stats, search queries, or create index requests. However, if a user-initiated task such as a create index command causes a cluster state update, the activity of this task might be reported by both task api and pending cluster tasks API.

This API returns information that reflects current state on the local cluster.
The connected field does not necessarily reflect whether a remote cluster is down or unavailable, only whether there is currently an open connection to it.
Elasticsearch does not spontaneously try to reconnect to a disconnected remote cluster.
To trigger a reconnection, attempt a cross-cluster search, ES|QL cross-cluster search, or try the resolve cluster endpoint.

Manually change the allocation of individual shards in the cluster. For example, a shard can be moved from one node to another explicitly, an allocation can be canceled, and an unassigned shard can be explicitly allocated to a specific node.
It is important to note that after processing any reroute commands Elasticsearch will perform rebalancing as normal (respecting the values of settings such as cluster.routing.rebalance.enable) in order to remain in a balanced state.
For example, if the requested allocation includes moving a shard from node1 to node2 then this may cause a shard to be moved from node2 back to node1 to even things out.
The cluster can be set to disable allocations using the cluster.routing.allocation.enable setting.
If allocations are disabled then the only allocations that will be performed are explicit ones given using the reroute command, and consequent allocations due to rebalancing.
The cluster will attempt to allocate a shard a maximum of index.allocation.max_retries times in a row (defaults to 5), before giving up and leaving the shard unallocated.
This scenario can be caused by structural problems such as having an analyzer which refers to a stopwords file which doesn’t exist on all nodes.
Once the problem has been corrected, allocation can be manually retried by calling the reroute API with the ?retry_failed URI query parameter, which will attempt a single retry round for these shards.
If true, then the request simulates the operation. It will calculate the result of applying the commands to the current cluster state and return the resulting cluster state after the commands (and rebalancing) have been applied; it will not actually perform the requested changes.
If true, then the response contains an explanation of why the commands can or cannot run.
Limits the information returned to the specified metrics.
If true, then retries allocation of shards that are blocked due to too many subsequent allocation failures.
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.

}All methods and paths for this operation:
Get comprehensive information about the state of the cluster.
The cluster state is an internal data structure which keeps track of a variety of information needed by every node, including the identity and attributes of the other nodes in the cluster; cluster-wide settings; index metadata, including the mapping and settings for each index; the location and status of every shard copy in the cluster.
The elected master node ensures that every node in the cluster has a copy of the same cluster state. This API lets you retrieve a representation of this internal state for debugging or diagnostic purposes. You may need to consult the Elasticsearch source code to determine the precise meaning of the response.
By default the API will route requests to the elected master node since this node is the authoritative source of cluster states.
You can also retrieve the cluster state held on the node handling the API request by adding the ?local=true query parameter.
Elasticsearch may need to expend significant effort to compute a response to this API in larger clusters, and the response may comprise a very large quantity of data. If you use this API repeatedly, your cluster may become unstable.
WARNING: The response is a representation of an internal data structure. Its format is not subject to the same compatibility guarantees as other more stable APIs and may change from version to version. Do not query this API using external monitoring tools. Instead, obtain the information you require using other more stable cluster APIs.

Secure settings are stored in an on-disk keystore. Certain of these settings are reloadable. That is, you can change them on disk and reload them without restarting any nodes in the cluster. When you have updated reloadable secure settings in your keystore, you can use this API to reload those settings on each node.
When the Elasticsearch keystore is password protected and not simply obfuscated, you must provide the password for the keystore when you reload the secure settings. Reloading the settings for the whole cluster assumes that the keystores for all nodes are protected with the same password; this method is allowed only when inter-node communications are encrypted. Alternatively, you can reload the secure settings on each node by locally accessing the API and passing the node-specific Elasticsearch keystore password.

All methods and paths for this operation:
Get a report with the health status of an Elasticsearch cluster. The report contains a list of indicators that compose Elasticsearch functionality.
Each indicator has a health status of: green, unknown, yellow or red. The indicator will provide an explanation and metadata describing the reason for its current health status.
The cluster’s status is controlled by the worst indicator status.
In the event that an indicator’s status is non-green, a list of impacts may be present in the indicator result which detail the functionalities that are negatively affected by the health issue. Each impact carries with it a severity level, an area of the system that is affected, and a simple description of the impact on the system.
Some health indicators can determine the root cause of a health problem and prescribe a set of steps that can be performed in order to improve the health of the system. The root cause and remediation steps are encapsulated in a diagnosis. A diagnosis contains a cause detailing a root cause analysis, an action containing a brief description of the steps to take to fix the problem, the list of affected resources (if applicable), and a detailed step-by-step troubleshooting guide to fix the diagnosed problem.
NOTE: The health indicators perform root cause analysis of non-green health statuses. This can be computationally expensive when called frequently. When setting up automated polling of the API for health status, set verbose to false to disable the more expensive analysis logic.

The connector and sync jobs APIs provide a convenient way to create and manage Elastic connectors and sync jobs in an internal index.
Connectors are Elasticsearch integrations for syncing content from third-party data sources, which can be deployed on Elastic Cloud or hosted on your own infrastructure.
This API provides an alternative to relying solely on Kibana UI for connector and sync job management. The API comes with a set of validations and assertions to ensure that the state representation in the internal index remains valid.
This API requires the manage_connector privilege or, for read-only endpoints, the monitor_connector privilege.
Update the last_seen field in the connector and set it to the current timestamp.
