Audit de la performance des systèmes Unix

Abstract : For a global company, the performance problematic is important, thus it allows a service according to end users or customers’ expectations, avoids unavaibility of her services and servers and finally optimizes the use of resources. In general this company has a core-team dedicated to this task. Each specialist is in charge of an array servers regarding to his skills. This document refers specially to possible tunables parameters and these who take place in operating system like Solaris, AIX and Redhat Enterprise. These optimizations are related with four different type of components reviewed sequentially: processor, memory, disk system and network according to the methodology path used in the performance audit. These components have to be monitored through specific metrics and commands, the output data must be analyzed and studied so that we can propose hints and tweaks. Nevertheless for a machine; some resources are virtualized or shared through different servers, some statements have to be reconsidered and thus modify our usual admitted approach in tuning. In order to help the specialist, some tools are used, here they are briefly evaluated also.
