Ravi Lachhman discusses the importance of logging in software engineering, emphasizing that as systems grow more distributed and complex, effective log management becomes crucial for monitoring system health and performance. Logs, which capture event outputs from systems, require careful engineering consideration, including decisions on verbosity and logging architecture. The article highlights the challenges of logging, such as the sheer volume of logs generated and the impact on system resources, and introduces Fluentd as a solution for achieving a consistent logging format. By integrating Fluentd with Harness ECS Delegate and leveraging AWS Firelens, log routing and aggregation are optimized, enhancing the ability to monitor and respond to system events. The piece underscores the value of using tools like Harness to transform logs into actionable insights and improve the confidence in system deployments.
