Monitoring Websites

With performance data, you can establish patterns that define peak periods of activity, audit capacity, build detailed upgrade plans, and learn how all the parts of your system really interact. Unfortunately, administrators are often unable to act on the data they collect—sometimes because they don't have a roadmap. The goal of this chapter is to help you not only collect the right data, but also to beat the odds and intelligently tune your system in the process of maximizing performance across the entire web service.

To help you with your task, the following major performance and optimization areas are discussed in this chapter:

  • Memory usage
  • Processor utilization
  • Disk I/O
  • Network bandwidth
  • Bandwidth throttling
  • Web connections
  • HTTP compression
  • Site configuration
