I started by looking <br />at the ntpdate utility, but it doesn't provide options for the query <br />count and timeout. I then looked at the perl Net::NTP perl module, but <br />its not suitable for direct use as a smokeping probe. The Net::NTP <br />module doesn't support a configuration timeout or error handling <br />routines. If you just wanted to write an NTP probe to measure NTP <br />response time and query success, it wouldn't be too difficult. <br />Implementing NTP authentication and NTP server response <br />parsing/integrity checking would be more difficult.<br /><br />Clinton.<br /><br />On 2013-06-12 02:36 PM, Aaron Toponce wrote:<br />> Has there been any thought abo

This is<br />after taking it down to 10 pings every 300 seconds. Also, it seems curl(1)<br />blocks, and prevents the other curl(1) probes from executing as seen in<br />http://zen.ae7.st/smokeping/?target=Internet. There are no gaps in the graphs<br />for the other probes (FPing, SSH and DNS).<br /><br />So, I guess take it down to 5 pings per 300 seconds?

It is pretty easy to add an NTP monitor to those other tools: nagios has the built-in check, and it's trivial to add a graph to cacti (here's a host that this discussion made me realize had an issue that needed correcting the other day):<br /><br /><br /><br />If you really want to add something to smoking, there are various examples from those other monitoring systems you might be able to convert over.<br /><br />The one I had grabbed back when I added NTP graphing uses:<br /><br /> /usr/bin/ntpq -c \"host $host\" -c ass -c rv<br /><br />but I did not save a reference to where I got it from, but perhaps you want to look at the these others that are similar:<br /><br /> http://docs.cacti.net/usertemplate:graph:ntp<br /> http://forums.cacti.net/about32521.html<br /><br />for pote
