DESCRIPTION:
To
solve performance problems in modern computing infrastructures, often
comprising thousands of servers running hundreds of applications, spanning
multiple tiers, you need tools that go beyond mere reporting. You need tools that
enable performance analysis of application workflow across the entire
enterprise. That's what PDQ (Pretty Damn Quick) provides. PDQ is an open-source
performance analyzer based on the paradigm of queues. Queues are ubiquitous in
every computing environment as buffers, and since any application architecture
can be represented as a circuit of queueing delays, PDQ is a natural fit for
analyzing system performance.
Building on the success of the first edition, this considerably expanded second
edition now comprises four parts. Part I contains the foundational concepts, as
well as a new first chapter that explains the central role of queues in
successful performance analysis. Part II provides the basics of queueing theory
in a highly intelligible style for the non-mathematician; little more than
high-school algebra being required. Part III presents many practical examples
of how PDQ can be applied. The PDQ manual has been relegated to an appendix in
Part IV, along with solutions to the exercises contained in each chapter.
Throughout, the Perl code listings have been newly formatted to improve
readability. The PDQ code and updates to the PDQ manual are available from the
