Log Data as the Basis for Effective Debugging
In this chapter, we walked through the basics of collecting, displaying, and interpreting data about a running system with PF enabled. Knowing how to find and use information about how your system behaves is useful for several purposes.
Keeping track of the status of a running system is useful in itself, but the ability to read and interpret log data is even more essential when testing your setup. Another prime use for log data is for tracking the effect of changes you make in the configuration, such as when tuning your system to give optimal performance. In the next chapter, we’ll focus on checking your configuration and tuning it for optimal performance, based on log data and other observations.
