[hobbit] Question about RRDTOOL Graphs in Xymon

[Jim Sloan]

You can use rrdfetch to grab specific data (min, avg, max) for a specific time period, or you can use rrddump to dump the full rrd to an XML file that can be parsed with an xml parser.

With this data, you can do any calculations you want on it.

Thanks for your help, the biggest difficulty for me is to be understable in english;) in fact I know how to fetch data from rrd files but I would like to know how is the most simple procedure to calculate avg/max/min that RRDtool prints in graphs.

Check where you have $INSTALLDIR/data/rrd on your hobbit server and you
will find these rrd files for each server in their own directory. They
are NOT in text format and you need to use the rrd tools to access the
raw data. See the section on custom graphs for an example on how to
dump one of these files.

Xymon collects the information from, in your case, Solaris. Then it 
stores the data in an rrd (round robin database) for later display on a 
graph.
