[ aws . iot ]



Returns the count, average, sum, minimum, maximum, sum of squares, variance, and standard deviation for the specified aggregated field. If the aggregation field is of type String , only the count statistic is returned.

Requires permission to access the GetStatistics action.

See 'aws help' for descriptions of global parameters.

--query-string <value>

[--generate-cli-skeleton <value>]


--index-name (string)

The name of the index to search. The default value is AWS_Things .

--query-string (string)

The query used to search. You can specify "*" for the query string to get the count of all indexed things in your Amazon Web Services account.

--aggregation-field (string)

The aggregation field name.

--query-version (string)

The version of the query used to search.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.


To search the device index for aggregate data

The following get-statistics example returns the number of things that have a property called connectivity.connected set to false (that is, the number of devices that are not connected) in their device shadow.

aws iot get-statistics \
    --index-name AWS_Things \
    --query-string "connectivity.connected:false"


    "statistics": {
        "count": 6

For more information, see Getting Statistics About Your Device Fleet in the AWS IoT Developer Guide.
