Monitoring Apache web server performance

This text discusses the monitoring of Apache performance in a three-part series. It begins by explaining what Apache is and its history, as well as comparing it to other popular web servers like NGINX and IIS. The key performance metrics that should be monitored are then outlined, including throughput and latency metrics, resource utilization and activity metrics, host-level resource metrics, and errors. These metrics can help identify bottlenecks or performance problems before they become user-facing issues. The text also delves into the differences between Apache's Multi-Processing Modules (MPMs) for Unix-like systems: prefork, worker, and event. It concludes by stating that the next step is to start collecting these metrics and parsing logs in order to monitor Apache web server performance effectively.
