nmon - tuning and benchmark tool

28 March,2012 by Jack Vamvas

Nmon is a tuner and benchmark tool  on Linux.  Capture disk, cpu, memory , filesystem, resource usage, virtual memory

As a DB2 DBA it's a very effective method of capturing different types of in data in one interface.

nmon  is useful in operation with  DB2 and Linux IO testing tools

Notes

1) Download nmon from http://nmon.sourceforge.net/pmwiki.php

 

 

2)  tar –xvf  filename.tar.gz  on the target server

 

3) Locate the correct binary , in my case –  nmon_linux_x86_64

 

4) Use to check if nmon is running : ps -ef | grep nmon

 

5) Use the file output option to Save the data file for analysis.
An example command to execute nmon in background to collect the data:

nmon -f -s 10 -c 60

This generates data in current directory for 600 seconds

6)  Load output file into nmon Analyzer tool in Excel
