Basic Monitoring of I/O on AIX
This paper is intended to provide a detailed and example based description on basic I/O monitoring for people who are new to performance analysis on AIX. The focus is to give background information on I/O flow through AIX systems, a list of best practice approaches, rules of thumb and examples for I/O performance analysis in a step by step guide. By restricting the scope to the basic tools shipped with AIX 5.3L on POWER5 machines this paper does not cover all monitoring areas such as storage. The reason is that the tools used for that purpose do not fit into the approach covered by this paper.
