NMON - powerful open source performance monitoring

Andy Wojnarek
Talk Description: 

Nigel's performance Monitor for Linux on POWER, x86, x86_64, Mainframe & now ARM (Raspberry Pi). This powerful utility was developed by Nigel Griffiths while working at IBM aimed at the IBM centric operating systems. Later it was written for Linux as well, targeting running on the IBM platforms and in 2009 it was open sourced.

The utility has two modes:

* In Online Mode it uses curses for efficient screen handling, which updates the terminal frequently for real-time monitoring.

* In Capture Mode, the data is saved to a file in CSV format for later processing and graphing. The file also includes important configuration details that are useful for recommending tuning.

In this talk I will show the strengths of nmon, and some tips and tricks in using this utilities.
