AWS IoT Core adds new logs to troubleshoot connectivity and authentication

Amazon Web Services has expanded AWS IoT Core's logging capabilities with two new CloudWatch log event types designed to help developers troubleshoot device connectivity and authentication issues across IoT deployments. The new Ping log event type captures MQTT Keep-alive messages, enabling administrators to identify devices or connections that fail to maintain active sessions. Meanwhile, the Connection.AuthNError log event type records rejected connection attempts due to authentication failures and provides detailed error codes to help diagnose credential and certificate problems. To enable these logging features, administrators need to configure event-level logging in their AWS IoT Core settings, specify the desired log level and CloudWatch log group destination, then opt into the new event types. The enhanced logging capabilities are now available across all AWS regions where IoT Core operates, providing IoT fleet managers with better visibility into connection health and security issues that can impact device performance and reliability.
