Asunto: Re: [smokeping-users] Get jitter

You might have good enough links that there isn't
enough jitter (smoke) to actually show up.  You could
do an:

rrdtool dump <filename.rrd> > filename.xml

and view the raw data (smokeping logging can also be
enabled to get similar numbers).  If you haven't
worked with XML and RRDTool before, it can take a
little while to get your bearings, but it should be
obvious enough to tell if all the values are really
close together (meaning you don't have much jitter).

You could also experiment with SmokePinging "other
stuff" on the Internet until you find something that
shows some smoke.
