Monitoring a slow system

About this series
The typical UNIX® administrator has a key range of utilities, tricks, and systems he
or she uses regularly to aid in the process of administration. There are key utilities,
command-line chains, and scripts that are used to simplify different processes.
Some of these tools come with the operating system, but a majority of the tricks
come through years of experience and a desire to ease the system administrator's
life. The focus of this series is on getting the most from the available tools across a
range of different UNIX environments, including methods of simplifying
administration in a heterogeneous environment.
