I started by looking at the ntpdate utility, but it doesn't provide options for the query count and timeout. I then looked at the perl Net::NTP perl module, but its not suitable for direct use as a smokeping probe. The Net::NTP module doesn't support a configuration timeout or error handling routines. If you just wanted to write an NTP probe to measure NTP response time and query success, it wouldn't be too difficult. Implementing NTP authentication and NTP server response parsing/integrity checking would be more difficult. Clinton.

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

Since I use multiple tools for different purposes mine aren't done directly in smokeping, though I do use ping for some things. 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): 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. The one I had grabbed back when I added NTP graphing uses: /usr/bin/ntpq -c \"host $host\" -c ass -c rv 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: http://docs.cacti.net/usertemplate:graph:ntp http://forums.cacti.net/about32521.html for potential conversion to smokeping if that's your preferred tool. -p -------------- next part -------------- An HTML attachment was scrubbed...
