Re: tool for nfs load

The site provides the details about using gnuplot but, I've generally found it easier to import the data from the raw file generated by collectL into Microsoft Excel and using its graphing capabilities.  I'm sure the much more savvy Gnuplot user could make it shine for you.

 

Anyway, the raw file is typically a compressed text file if the compressed option is configured.  Otherwise it's just a standard text file that you can import into any application that can manipulate delimited text files.

 

Experiment and enjoy but, be aware that depending on the settings you pass the utility you can potentially generate a rather large volume of data.  The good thing is, the utility will allow for a specific range of data points to be observed by using whatever metric of interest that's offered.

There's another tool I've used called "collectL".  It's on the same lines as SAR (which is also very good) but offers a much greater degree of sampling grandularity.  It'll also work well with tools like excel or gnuplot for graphing. 
 
Anyway, here's the link: http://collectl.sourceforge.net/
