Get a document count Generally available

GET /_cat/count/{index}
Api key auth

All methods and paths for this operation:

POST /_cat/count

GET /_cat/count
POST /_cat/count/{index}
GET /_cat/count/{index}

Get quick access to a document count for a data stream, an index, or an entire cluster. The document count only includes live documents, not deleted documents which have not yet been removed by the merge process.

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 count API.

NOTE: Starting in Elasticsearch 9.3.0, this endpoint also supports the POST method. This is primarily intended for project routing in serverless environments.

Required authorization

  • Index privileges: read

Path parameters

  • index string | array[string] Required

    A comma-separated list of data streams, indices, and aliases used to limit the request. It supports wildcards (*). To target all data streams and indices, omit this parameter or use * or _all.

Query parameters

  • h string | array[string]

    A comma-separated list of columns names to display. It supports simple wildcards.

    Supported values include:

    • epoch (or t, time): The Unix epoch time in seconds since 1970-01-01 00:00:00.
    • timestamp (or ts, hms, hhmmss): The current time in HH:MM:SS format.
    • count (or dc, docs.count, docsCount): The document count in the cluster or index.

    Values are epoch, t, time, timestamp, ts, hms, hhmmss, count, dc, docs.count, or docsCount.

  • s string | array[string]

    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.

  • format string

    Specifies the format to return the columnar data in, can be set to text, json, cbor, yaml, or smile.

    Default value is text.

  • help boolean

    When set to true will output available columns. This option can't be combined with any other query string option.

    Default value is false.

  • v boolean

    When set to true will enable verbose output.

    Default value is false.

  • bytes string

    Sets the units for columns that contain a byte-size value. Note that byte-size value units work in terms of powers of 1024. For instance 1kb means 1024 bytes, not 1000 bytes. If omitted, byte-size values are rendered with a suffix such as kb, mb, or gb, chosen such that the numeric value of the column is as small as possible whilst still being at least 1.0. If given, byte-size values are rendered as an integer with no suffix, representing the value of the column in the chosen unit. Values that are not an exact multiple of the chosen unit are rounded down.

    Values are b, kb, mb, gb, tb, or pb.

  • time string

    Sets the units for columns that contain a time duration. If omitted, time duration values are rendered with a suffix such as ms, s, m or h, chosen such that the numeric value of the column is as small as possible whilst still being at least 1.0. If given, time duration values are rendered as an integer with no suffix. Values that are not an exact multiple of the chosen unit are rounded down.

    Values are nanos, micros, ms, s, m, h, or d.
