Here is a very nice introduction to code instrumentation from David Njoku. Instrumentation is very important for your code and read this article to learn why. Of course it is well-known that Oracle database is one of the most well-instrumented software in the world, but instrumentation is equally important for software of any scale.
The article does not give many details on the "how" part of instrumentation, as it puts more weight on the "why it is necessary". Although it gives a brief outline.
An open source solution for instrumenting your PL/SQL code is Logger. This is extremely useful for APEX applications where debugging can be really difficult if your code does not leave the appropriate traces behind in order to find out what has happened (i.e., it has not been instrumented!). Check it out.
Enjoy!
