Nmon tool

How to analyze nmon output or is there any tool for analyzing.

Well you can try the commands to get the output of Nmon tool,

The following command captures the data every 30 secs for an hour and stores output into the file.

nmon -f -s 30 -c 120

Above command creates the output file in the current directory called <hostname>_date_time.nmon

You can even
type the nmon -? command for brief details
or
Type the nmon -h command for full details.

I just hope this solves you r query.

There is such a tool, alas it is only for Excel (for crying out loud).

Basically you feed the file collected by NMON in daemon mode to it and can generate all sorts of graphs then.

The tools is called "NMON analyzer" and can be downloaded from the IBM website.
