Re: [ntp:questions] MSF Anthorn, UK down
Hello! Why have such important service no backup transmitter/antenna like DCF77?

Whereas DCF77 might have a backup transmitter (I don't know), I observe DCF77 being down very often, albeit for short durations (5-10 mins). When I do receive it the signal is strong, so I don't think my observations are due to being too far away (I'm in Northern Belgium).

[ntp:questions] nagios
I am trying to monitor NTP servers with nagios. I use the standard plugin check_ntp_peer. It appears that it is only checking the offset and jitter of the currently selected peer. When I run check_ntp_peer with some threshold it returns the same values as present on the ntpq output line with * at the beginning. I think this is wrong. It should do the equivalent of ntpq -c rv and pick the offset and sys_jitter values from there. Is anyone aware of a nagios plugin that does that? ___ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions

Hi Mostly too weak in Lancashire UK but at least it has a very accurate phase shift seconds marker. MSF and GPS for me have occasional blackouts, ISTR inversion layer effects used to be common in this area but apparently it's now unknown. MSF was ok as fallback on rare occasions when internet was down. David ___ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions

H Ok I see that this one at least uses ntpq -c readvar. I would prefer an implementation that uses the readvar packet itself, as I think that it can return more precision than ntpq does.
