Instrumentation allows you to determine the running state of a system once it has been deployed. This is crucially important today since the people supporting systems are unlikely to be the same people who developed them. Like good error handling, instrumentation is best done at development time. A sound instrumentation policy must be established at the beginning of the development process to determine what should be instrumented, why, where, and how.
