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.
