How can I use the remote check capabilities and monitoring tools for diagnosing unusual behavior in a fleet of IoT devices?

 In the context of AWS, you can remotely check an IoT device and troubleshoot issues without physical access by using the several steps which are given below:-

Remotely monitoring and management tool

You can implement an RMM tool such as AWS IoT device management, or Azure IoT Hub. Here is the example given by using the AWS IoT device management:-

Aws iot describe-thing –thing-name MyIoTDevice

Data collection and analysis

You can collect relevant data from the IoT device such as sensor reading, logs, connectivity status, and firmware version. Here is the example given by using AWS IoT SDK:-

Import boto3

Iot_client = boto3.client(‘iot’)

Response = iot_client.describe_thing(

    thingName=’MyIoTDevice’

)

Print(response)

Remote diagnostics

You can perform remote diagnostics by sending commands or even Configurations to the IoT devices and observing their response. Here is the example given of sending a command by using IoT device management:-

Aws iot-data publish –topic “cmd/MyIoTDevice” –payload ‘{“command”: “restart”}’

Integration with monitoring system

You can integrate the IoT device with monitoring systems like Amazon Cloudwatch, Azure monitor, etc for real-time performance metrics and alerts. Here is the example given of cloud watch alarms creation by using the AWS command line interface:-

Aws cloud watch put-metric-alarm –alarm-name “HighTemperatureAlarm” 

--metric-name “Temperature” –namespace “MyIoTDeviceMetrics” 

--statistic “Average” –period 300 –threshold 50 –comparison-operator “GreaterThanThreshold” 

--evaluation-periods 1 –alarm-actions “arn:aws:sns:us-east-1:123456789012:MySNSAlarmTopic”
