search-entities

Description

Searches for entities of the specified type. You can search for entities in your namespace and the public namespace that you’re tracking.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

search-entities is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: descriptions

Synopsis

  search-entities
--entity-types <value>
[--filters <value>]
[--namespace-version <value>]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]

Options

--entity-types (list)

The entity types for which to search.

(string)

Syntax:

"string" "string" ...

Where valid values are:
  DEVICE
  SERVICE
  DEVICE_MODEL
  CAPABILITY
  STATE
  ACTION
  EVENT
  PROPERTY
  MAPPING
  ENUM

--filters (list)

Optional filter to apply to the search. Valid filters are NAME NAMESPACE , SEMANTIC_TYPE_PATH and REFERENCED_ENTITY_ID . REFERENCED_ENTITY_ID filters on entities that are used by the entity in the result set. For example, you can filter on the ID of a property that is used in a state.

Multiple filters function as OR criteria in the query. Multiple values passed inside the filter function as AND criteria.

(structure)

An object that filters an entity search. Multiple filters function as OR criteria in the search. For example a search that includes a NAMESPACE and a REFERENCED_ENTITY_ID filter searches for entities in the specified namespace that use the entity specified by the value of REFERENCED_ENTITY_ID .

name -> (string)

The name of the entity search filter field. REFERENCED_ENTITY_ID filters on entities that are used by the entity in the result set. For example, you can filter on the ID of a property that is used in a state.

value -> (list)

An array of string values for the search filter field. Multiple values function as AND criteria in the search.

(string)

Shorthand Syntax:

name=string,value=string,string ...

JSON Syntax:

[
  {
    "name": "NAME"|"NAMESPACE"|"SEMANTIC_TYPE_PATH"|"REFERENCED_ENTITY_ID",
    "value": ["string", ...]
  }
  ...
]

--namespace-version (long)

The version of the user’s namespace. Defaults to the latest version of the user’s namespace.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a NextToken is provided in the command’s output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

Examples

To search for entities

The following search-entities example searches for all entities of type EVENT.

aws iotthingsgraph search-entities \
    --entity-types "EVENT"

Output:
