Apache's status module provides high-level metrics about its performance, and Apache logs offer even more detailed information about each client request. By consulting both sources, you can identify degradations and troubleshoot potential issues in real-time. The status module exposes various metrics, including total accesses/hits, CPU load, uptime, requests per second, and bytes per second. ExtendedStatus provides additional metrics, such as the number of bytes actually served. Apache logs offer customizable log formats, allowing you to track specific information about each request, including latency. Open-source tools like Apachetop and Atop can parse access logs for useful statistics and display them on the command line. These tools enable real-time monitoring of incoming requests and provide various metrics, such as the rate of requests and bytes served per second. Additionally, Datadog offers an integration with Apache to help visualize metrics from web servers in minutes, integrating with more than 850 technologies and providing context for performance metrics and event data from various sources.
