I have always thought that no one should ever consider using alerts as a basis for triage24—despite the overwhelming number of client initiatives attempting (unsuccessfully) to do exactly that. Today there is the Information Technology Infrastructure Library (ITIL)25 , which was defined by the United Kingdom Computing and Telecommunications Agency as the generally accepted model for IT service management, of which performance is a designated discipline26.

Suddenly, business was not only looking over the shoulder of IT but actually assuming more direct responsibility for performance issues. This business participation accelerated the focus on transactions and user experience because these are the quantities that have meaning for business. 23 Emphasizing Transactions in Addition to Resources The essential difference between APM and availability management (AM) is the visibility into each and every user transaction. The transactional context is what makes analysis of a distributed computing problem tractable.

If you find that your current or proposed activity has missed a few points, then the next part of the book, “Planning an APM Initiative,” is where you will find some tactical activities to help address those gaps or to flesh out a comprehensive plan. If you have already completed the initiative planning and have made a technology selection, then you are ready for managing a deployment. I would expect you to skim over the remaining chapters in this first part and maybe find something you overlooked.
