get-percentiles

Description

Groups the aggregated values that match the query into percentile groupings. The default percentile groupings are: 1,5,25,50,75,95,99, although you can specify your own when you call GetPercentiles . This function returns a value for each percentile group specified (or the default percentile groupings). The percentile group "1" contains the aggregated field value that occurs in approximately one percent of the values that match the query. The percentile group "5" contains the aggregated field value that occurs in approximately five percent of the values that match the query, and so on. The result is an approximation, the more values that match the query, the more accurate the percentile values.

Requires permission to access the GetPercentiles action.

Options

--index-name (string)

The name of the index to search.

--query-string (string)

The search query string.

--aggregation-field (string)

The field to aggregate.

--query-version (string)

The query version.

--percents (list)

The percentile groups returned.

(double)

Syntax:

double double ...

--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.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To group the aggregated values that match the query into percentile groupings

You can use the following setup script to create 10 things representing 10 temperature sensors. Each new thing has 1 attribute.

# Bash script. If in other shells, type `bash` before running
Temperatures=(70 71 72 73 74 75 47 97 98 99)
for ((i=0; i<10 ; i++))
do
    thing=$(aws iot create-thing --thing-name "TempSensor$i" --attribute-payload attributes="{temperature=${Temperatures[i]}}")
    aws iot describe-thing --thing-name "TempSensor$i"
done

Example output of the setup script:

{
    "version": 1,
    "thingName": "TempSensor0",
    "defaultClientId": "TempSensor0",
    "attributes": {
        "temperature": "70"
    },
    "thingArn": "arn:aws:iot:us-east-1:123456789012:thing/TempSensor0",
    "thingId": "example1-90ab-cdef-fedc-ba987example"
}

The following get-percentiles example queries the 10 sensors created by the setup script and returns a value for each percentile group specified. The percentile group "10" contains the aggregated field value that occurs in approximately 10 percent of the values that match the query. In the following output, {"percent": 10.0, "value": 67.7} means approximately 10.0% of the temperature values are below 67.7.

aws iot get-percentiles \
    --aggregation-field "attributes.temperature" \
    --query-string "thingName:TempSensor*" \
    --percents 10 25 50 75 90

Output:

{
    "percentiles": [
        {
            "percent": 10.0,
            "value": 67.7
        },
        {
            "percent": 25.0,
            "value": 71.25
        },
        {
            "percent": 50.0,
            "value": 73.5
        },
        {
            "percent": 75.0,
            "value": 91.5
        },
        {
            "percent": 90.0,
            "value": 98.1
        }
    ]
}
