A logger represents logging settings for the AWS IoT Greengrass group, which can be stored in CloudWatch and the local file system of your core device.

All log entries include a timestamp, log level, and information about the event. For more information, see Monitoring with AWS IoT Greengrass Logs in the Developer Guide .

In an AWS CloudFormation template, the Loggers property of the AWS::Greengrass::LoggerDefinitionVersion resource contains a list of Logger property types.

Example

// The code below shows an example of how to instantiate this type.

  component: 'component',
  id: 'id',
  level: 'level',
  type: 'type',

  // the properties below are optional

Properties

NameTypeDescription
componentstringThe source of the log event.
idstringA descriptive or arbitrary ID for the logger.
levelstringThe log-level threshold.
typestringThe storage mechanism for log events.
space?numberThe amount of file space (in KB) to use when writing logs to the local file system.

component

Type: string

The source of the log event.

Valid values are GreengrassSystem or Lambda . When GreengrassSystem is used, events from Greengrass system components are logged. When Lambda is used, events from user-defined Lambda functions are logged.
