The text discusses the importance of health checks in containerized applications on AWS Elastic Container Service (ECS), particularly intermittent health checks that can lead to unpredictable behavior, higher costs, and performance issues. It highlights the challenges posed by these errors, including brief periods of downtime for end users and impact on scalability. The article then introduces Lumigo, a troubleshooting platform built for microservices, which provides deep insights into the behavior and performance of serverless and containerized applications. Lumigo offers features such as a comprehensive dashboard, a powerful tracer that allows tracing of application execution, real-time logs, and crash detection capabilities to help identify and resolve issues with intermittent health checks. Strategies for improving health check reliability are also discussed, including retrying health check requests, setting timeouts, and paying attention to error handling within the application.
