[rrd-users] Getting AVG info from RRD Files

Hi Juvenal,

Hoe come? I copied and pasted the given URL in the browser and the nice docs came normally:

"rrdtool fetch filename CF [--resolution|-r resolution] [--start|-s start] [--end|-e end] [--daemon address]

DESCRIPTION
The fetch function ... will analyze the RRD and try to retrieve the data in the resolution requested. 
The data fetched is printed to stdout. *UNKNOWN* data is often represented by the string "NaN" 
depending on your OS's printf function." ...

And so on, There are also examples included, so you can "play" with them until getting what you 
need. Of course, you will have to process data provided by "fetch" accordingly to your wishes.

jh :)
