Best practices for AIX monitoring | How to analyze the statistics data

Get AIX statistics data using nmon

Overview

Use the nmon data collection model to collect detailed status data about the operating system for further analysis.

This example collects nmon performance results 180 times with an interval of 60 seconds, writing results to file: hostname.

The t parameter is used to focus our attention on the status of the top processes.

nmon -f -t -r hostname -s 60 -c 180

A result file named hostname_timeSeries.nmon will be generated in the current directory.
