Statistics File Issues
ntpd
can generate a variety of statistics as it runs.
Over time, any of these statistics files may have undergone a change in its content or format which makes it difficult to analyze "previous" and "current" data.
Let's use this page to discuss these issues and evolve a solution.
What about generating a "comment line" as the first line generated for every statistics file?
Perhaps something like:
#loopstats v1
# day now offset freq*1e6 jitter stability*1e6 spoll
This way we could easily
grep
out the comment lines and/or use a perl program to combine data from different versions of each statistics file into the desired format.
