AWS IoT Events-Data examples using AWS CLI

The following code examples show you how to perform actions and implement common scenarios by using the AWS Command Line Interface with AWS IoT Events-Data.

Actions are code excerpts from larger programs and must be run in context. While actions show you how to call individual service functions, you can see actions in context in their related scenarios.

Each example includes a link to the complete source code, where you can find instructions on how to set up and run the code in context.

The following code example shows how to use batch-put-message.

AWS CLI

To send messages (inputs) to AWS IoT Events

The following batch-put-message example sends a set of messages to the AWS IoT Events system. Each message payload is transformed into the input you specify ( inputName ) and ingested into any detectors that monitor that input. If multiple messages are sent, the order in which the messages are processed isn't guaranteed. To guarantee ordering, you must send messages one at a time and wait for a successful response.

aws iotevents-data batch-put-message \ --cli-binary-format raw-in-base64-out \ --cli-input-json file://highPressureMessage.json

Contents of highPressureMessage.json:

{ "messages": [ { "messageId": "00001", "inputName": "PressureInput", "payload": "{\"motorid\": \"Fulton-A32\", \"sensorData\": {\"pressure\": 80, \"temperature\": 39} }" } ] }

Output:

{ "BatchPutMessageErrorEntries": [] }

The following code example shows how to use put-logging-options.

AWS CLI

To set logging options

The following list-tags-for-resource example sets or updates the AWS IoT Events logging options. If you update the value of any loggingOptions field, it takes up to one minute for the change to take effect. Also, if you change the policy attached to the role you specified in the roleArn field (for example, to correct an invalid policy) it takes up to five minutes for that change to take effect.

aws iotevents put-logging-options \ --cli-input-json file://logging-options.json

Contents of logging-options.json:

{ "loggingOptions": { "roleArn": "arn:aws:iam::123456789012:role/IoTEventsRole", "level": "DEBUG", "enabled": true, "detectorDebugOptions": [ { "detectorModelName": "motorDetectorModel", "keyValue": "Fulton-A32" } ] } }
