[ntp:questions] noise and stability values

Hi folks,

A few years ago I started graphing my NTP server's performance. The 
machine ran Debian lenny with ntp v4.2.4. However, after recently 
upgrading to squeeze, which comes with ntp v4.2.6, I noticed that two 
system variables included in my graphs -- noise and stability -- are no 
longer present: neither in the output of "ntpq -c rv", nor in its 
associated manual, ntpq.html, which is part of the ntp-doc package. Well, 
actually the noise variable wasn't mentioned in the previous version of 
the manual either (dated July 28, 2005), but is was present in the output 
from the above command.

So, can ntpq no longer be used to examine a system's noise and stability 
variables, or is it currently necessary to use different command?
