Amazon IoT metrics and dimensions - Amazon IoT Core
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Amazon IoT metrics and dimensions

When you interact with Amazon IoT, the service sends metrics and dimensions to CloudWatch every minute. You can use Amazon IoT, use the CloudWatch console or Amazon CLI to view these metrics.

To view metrics using the CloudWatch console, open the CloudWatch console. In the navigation pane, choose Metrics and then choose All metrics. In the Browse tab, search for Amazon IoT to view the list of metrics. Metrics are grouped first by the service namespace, and then by the various dimension combinations within each namespace.

To view metrics using Amazon CLI, run the following command.

aws cloudwatch list-metrics --namespace "Amazon/IoT"

While the count is generally accurate, the distributed architecture of Amazon IoT Core makes it difficult to maintain a precise count of registered things.

The statistic to use for this metric is:

  • Max to report the total number of things that have been registered. For a count of things registered during the CloudWatch aggregation window, see the RegisterThingFailed metric.

Dimensions: ClaimCertificateId

CreateKeysAndCertificateFailed

The metric is emitted in both Success (value = 0) and Failure (value = 1) cases. This metric can be used to track the number of certificates created and registered during the CloudWatch-supported aggregation windows, such as 5 min. or 1 hour.

The statistics available for this metric are:

  • Sum to report the number of failed calls.

  • SampleCount to report the total number of successful and failed calls.

CreateCertificateFromCsrFailed

The number of failures that occurred by calls to the CreateCertificateFromCsr MQTT API.

The metric is emitted in both Success (value = 0) and Failure (value = 1) cases. This metric can be used to track the number of things registered during the CloudWatch-supported aggregation windows, such as 5 min. or 1 hour.

The statistics available for this metric are:

  • Sum to report the number of failed calls.

  • SampleCount to report the total number of successful and failed calls.

RegisterThingFailed

The number of failures that occurred by calls to the RegisterThing MQTT API.

The metric is emitted in both Success (value = 0) and Failure (value = 1) cases. This metric can be used to track the number of things registered during the CloudWatch-supported aggregation windows, such as 5 min. or 1 hour. For the total number of things registered , see the ApproximateNumberOfThingsRegistered metric.

The statistics available for this metric are:

The following table shows the metrics for Amazon IoT Core for LoRaWAN. For more information, see Amazon IoT Core for LoRaWAN metrics.

Amazon IoT Core for LoRaWAN metrics
Metric Description

Active devices/gateways

The number of active LoRaWAN devices and gateways in your account.

Uplink message count

The number of uplink messages that are sent within a specified time duration for all active gateways and devices in your Amazon Web Services account. Uplink messages are messages that are sent from your device to Amazon IoT Core for LoRaWAN.

Downlink message count

The number of downlink messages that are sent within a specified time duration for all active gateways and devices in your Amazon Web Services account. Downlink messages are messages that are sent from Amazon IoT Core for LoRaWAN to your device.

Message loss rate

After you've added your device and connected to Amazon IoT Core for LoRaWAN, your device can initiate an uplink message to start exchanging messages with the cloud. You can use this metric to then track the rate of uplink messages that are lost.

Join metrics

After you've added your device and gateway, you perform a join procedure so that your device can send uplink data and communicate with Amazon IoT Core for LoRaWAN. You can use this metric to obtain information about join metrics for all active devices in your Amazon Web Services account.

Average received signal strength indicator (RSSI)

You can use this metric to monitor the average RSSI (Received signal strength indicator) within the specified time duration. RSSI is a measurement that indicates if the signal is strong enough for a good wireless connection. This value is negative and must be closer to zero for a strong connection.

Average signal to noise ratio (SNR)

You can use this metric to monitor the average SNR (Signal-to-noise ratio) within the specified time duration. SNR is a measurement that indicates if the received signal is strong enough compared to the noise level for a good wireless connection. The SNR value is positive and must be greater than zero to indicate that the signal power is stronger than the noise power.

Gateway availability

You can use this metric to obtain information about the availability of this gateway within a specified time duration. This metric displays the websocket connection time of this gateway for a specified time duration.
