Path parameters

• index string | array[string] Required

  A comma-delimited list of index patterns.

Query parameters

• timeout string

  The 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.

  • indices array[object] Required

    An array of follower index statistics.

    Hide indices attributes Show indices attributes object

    • index string Required
    • shards array[object] Required

      • bytes_read number Required

        The total of transferred bytes read from the leader. This is only an estimate and does not account for compression if enabled.

      • failed_read_requests number Required

        The number of failed reads.

      • failed_write_requests number Required

        The number of failed bulk write requests on the follower.

      • fatal_exception object

        Cause and details about a request failure. This class defines the properties common to all error types. Additional details are also provided, that depend on the error type.

        • type string Required

          The type of error

        • reason
