AWS IoT Event-Based Logging

AWS IoT now supports event-based logging, a new capability that helps developers reduce Amazon CloudWatch costs while improving log management efficiency. This feature enables targeted logging for individual events with customizable log levels and Amazon CloudWatch log group destinations.

With Event-Based Logging, you can set different log levels for different types of IoT events based on their operational importance. For example, you can configure INFO-level logging for certificateProvider events while maintaining ERROR-level logging for less critical activities like connectivity events. The granularity allows you to maintain comprehensive visibility into your IoT operations without the overhead of logging every activity at the same verbosity level, improving log searchability and analysis efficiency while helping to reduce costs.

What to do

  • Configure Event-Based Logging through the AWS IoT console, CLI, or API.
  • Set different log levels for various IoT events based on operational importance.
  • Visit the AWS IoT Developer Guide to learn more about configuring Event-Based Logging.
