Web log analysis is a critical tool for understanding and improving the performance, security, and user experience of web services. Monitoring web access logs helps identify errors and troubleshoot issues, detect malicious activities, and ensure operational excellence by analyzing traffic patterns and HTTP status codes. These logs also provide valuable insights for search engine optimization (SEO) by tracking site indexing activities and addressing disparities in traffic measurements due to ad blockers. Furthermore, web logs reveal user experience metrics by detailing site latency and user-agent information, which are crucial for optimizing site performance, especially for mobile users. Integrating web logs with other observability data creates a comprehensive overview that can drive significant system improvements across various operational areas.
