By tracing, you are able to collect system data in real time that is when the process is running. A trace can be used to isolate and understand system problems and check where in the system you are faced with bottlenecks. Chapter 9 namely "Linux Trace Toolkit" of this book looks at just that. As I explained earlier, a profiler is a program which aids the programmer to analyse the performance of applications and the kernel there by help him optimise his programs.

Where as in the first chapter, the author had covered how one can profile using simple tools like ' date ', here chapter 10 he explores the use of a more complex profiler tool called oprofile.

The next chapter chapter 11 is my favourite. To those in the dark, UML is a complete Linux kernel which has its own scheduler and virtual memory system. UML has gained the fascination of programmers around the world mainly because it helps the programmer test his applications in a complete isolated Linux environment within the parent OS. I really liked the tips section in this chapter which revealed new insights into the working of UML.

Chapter 12 deals with the topic of Dynamic Probes. They help a programmer in acquiring diagnostic information without including special blocks of code in the program. Dynamic probes can also be used as a tracing mechanism for both user and kernel space.

If chapter 3 dealt with GNU debugger gdb , chapter 13 deals with kernel level debuggers. This chapter covers two kernel level debuggers kgdb and kdb.
