# Configure Logging for AWS IoT Wireless
<a name="configure-logging"></a>

Before you can monitor and log AWS IoT Wireless activity, first enable logging for your AWS IoT Wireless resources. You can enable logging by using the AWS IoT console, the AWS IoT Wireless API, or the AWS CLI.

When starting to monitor AWS IoT Wireless resources, you can use the default configuration. To do this, you can skip this topic and proceed to [Monitor AWS IoT Wireless using CloudWatch Logs](cloud-watch-logs.md) to monitor your logs. After reviewing the initial logs, you can change the default log level to `ERROR`, which is less verbose. You can then set a more verbose, resource-specific log level on resources that might need more attention. Log levels can be changed whenever you want.

## AWS IoT Wireless resources and log levels
<a name="log-levels-resources"></a>

Before you use the console or the API, use the following table to learn about the different log levels and the resources that you can configure logging for. The table shows parameters that you see in the CloudWatch logs when you monitor the resources. How you configure the logging for your resources will determine the logs you see in the console.

For information about what a sample CloudWatch logs looks like and how you can use these parameters to log useful information about the AWS IoT Wireless resources, see [View CloudWatch AWS IoT Wireless log entries](cwl-format.md).


**Log levels and resources**  

| Name | Possible values | Description | 
| --- | --- | --- | 
| logLevel |  `INFO`, `ERROR`, or `DISABLED`  |  [\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/iot-wireless/latest/developerguide/configure-logging.html)  | 
| resource |  `WirelessGateway`, `WirelessDevice`, or `FuotaTask`  |  The type of the resource, which can be `WirelessGateway`, `WirelessDevice`, or `FuotaTask`.  | 
| wirelessGatewayType | LoRaWAN | The type of the wireless gateway, when resource is WirelessGateway, which is always LoRaWAN. | 
| wirelessDeviceType | LoRaWAN or Sidewalk | The type of the wireless device, when resource is WirelessDevice, which can be LoRaWAN or Sidewalk. | 
| fuotaTaskType | LoRaWAN | The type of the FUOTA task, when resource is fuotaTask, which is always LoRaWAN. | 
| wirelessGatewayId | - | The identifier of the wireless gateway, when resource is WirelessGateway. | 
| wirelessDeviceId | - | The identifier of the wireless device, when resource is WirelessDevice. | 
| fuotaTaskId | - | The identifier of the FUOTA task, when resource is FuotaTask. | 
| event | Join, Rejoin, Registration, Uplink\$1data, Downlink\$1data, CUPS\$1Request, Certificate, and Fuota | The type of event being logged, which depends on whether the resource that you're logging is a wireless device, a wireless gateway, or a FUOTA task. For more information, see [View CloudWatch AWS IoT Wireless log entries](cwl-format.md).  |
