HOWTO: Collect an AIX performance baseline
User Rating: / 8

Use nmon as basis for performance analysis

Too often I visit customers and "discover" that they have one of many condiftions that make analysis of performance very difficult. Generally there is either too little, too much, or (too) different data collected to do a proper analysis. At the end of this article I provide a script as an example of how performance data collection can be standardized. In between I discuss the reasoning for the number of collections, as well as number and duration of the samples.

Although many customers have adopted the use of nmon for collecting performance statistics their collection process is rarely standardized. When it is standardized the intended detail of data is often lost in the reports because the defaults taken or chosen are not sized right.
