Hi, Martin !

Got you a solution for solaris ... or someone else ?

.. and second, who knows a good pluggin for monitoring timeservers for 
themselves  ?

thanks & cheers,

Hey Henrik,

Thanks for this, I didn't even know I wanted one of these until it was 
mentioned!

Only issue for me is a Solaris-specific one, in that "rv 0 offset" 
doesn't work because the default Solaris ntpq program doesn't 
understand 0 as a valid association. I'm still trying to figure out a 
different way of getting the system time offset on a Solaris box 
(without installing a different NTP client!), have you heard of anything?

What do I need to do to make the graphs appear?

Heh, I didn't realize that had snuck into the distribution :-)

It's using data from "ntpq", running as a client-side add-on
on the box that you want to monitor ntp for. It's dead simple:


#!/bin/sh

# This script is an extension for the BB client running on
# your server. It will feed data about the local NTP daemon
# into Hobbit, where the offset between the NTP reference
# clock and the local clock will be graphed.

$BB $BBDISP "data $MACHINE.ntpstat

`ntpq -c \"rv 0 offset\"`
"

exit 0

"ntpq -c peers" also reports offset.
On solaris 9/10 clients, you could use:


$BB $BBDISP "data $MACHINE.ntpstat

`echo offset=\`ntpq -c peers | tail +3 | head -1 | awk '{ print $9 }'\``
"
exit 0
