[time-nuts] monitoring NTP servers?

[Anders Wallin]

Hi all,
Is there a ready made set of scripts for monitoring a bunch of NTP servers?
Preferably for generic unix/linux like ubuntu.

I imagine it would look something like:
1. measure data with a test machine, either use output of "ntpq -p" or
perhaps python and ntplib. Variable measurement interval, perhaps 60s or so.
2. store relevant data into RRDTool database (offsets, delay, jitter, etc)
3. produce graphs with RRDGraph, and possibly Alarms (e-mail?) if a server
goes offline or way out of sync.

thanks,
Anders
