[rrd-users] Re: Retrieving numeric data from rrdtool graph command

[Darryl Dunkin]

Yes, use 'print' in your graph parameters and the results will be
printed to stdout.

Results will include your image size (0x0 if you only used the print
statements) and the results.

Subject: [rrd-users] Retrieving numeric data from rrdtool graph command

Gang:

This is probably a newbie question, but I did make the attempt to  
read the docs and search the web, so forgive me if this is real  
obvious and feel free to point me to a URL.

I have a graph defined using RRDTool 1.2 that uses a VDEF to return a  
95th percentile calculation. It works fine, and that number appears  
nicely on the graph.

My question: Can I get that number some other way, outside the graph,  
so that I can use it in a script?
