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.

See 'aws help' for descriptions of global parameters.

Synopsis

  get-percentiles
[--index-name <value>]
--query-string <value>
[--aggregation-field <value>]
[--query-version <value>]
[--percents <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--index-name (string)

The name of the index to search.

--query-string (string)

The query string.

--aggregation-field (string)

The field to aggregate.

--query-version (string)

The query version.

--percents (list)

The percentile groups returned.

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.

See 'aws help' for descriptions of global parameters.

Examples

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
        }
    ]
}
