Thanks! I have got some parent graphs, if anyone is interested; http://www.sput.nl/ntpstats/remote/ The scripts generate meta files, so each image has its own expiry date and refresh time.

I believe the problem is the positive frequency value, as it seems to have no trouble graphing saturn's negative values properly. At any rate, adding the option '--alt-y-grid' should solve the problem. I put the script I use for apollo's plots in my scripts/ntp directory for an example: http://saturn.dennishilberg.com/scripts/ntp/graph_ntp_values.apollo Hope that helps, -- Dennis Hilberg Jr NTP Server Information: http://saturn.dennishilberg.com/ntp.php ___ questions mailing list questions@lists.ntp.org https://lists.ntp.org/mailman/listinfo/questions

It will do what you are asking for. I have my scripts available that I use to create my RRDtool plots. Check out http://saturn.dennishilberg.com/ntp.html for the data plots, and http://saturn.dennishilberg.com/scripts/ntp for the actual scripts. Also, be sure to check out Steven Bjork's website http://www.wraith.sf.ca.us/ntp/index.html#monitoring for help with creating RRDtool plots with ntp. It helped me out a lot with figuring out RRDtool, as documentation alone is not much help. The documentation is somewhat helpful though, http://oss.oetiker.ch/rrdtool/doc/index.en.html . But it's much more helpful to see some scripts in action rather than rely completely on the documentation, IMHO.

It doesn't do negative numbers. You should look into RRDTool, as it solves most of your issues. I'm pretty sure that I've seen graphs produced by RRD in use with NTP by others that read this group. (I have not yet, myself). http://oss.oetiker.ch/rrdtool/ Cheers, Roger ___ questions mailing list questions@lists.ntp.org https://lists.ntp.org/mailman/listinfo/questions
Re: [ntp:questions] NTP MRTG graphs?
Pete, The graphs produced by me and shown on web pages and in my book use MatLab programs. I am happy to share those for folks who have that product, which is endemic to just about every engineering department in the country.

There is some information at: http://support.ntp.org/Support/MonitoringAndControllingNTP and I think it would be Swell if more people added more notes or scripts there. H ___ questions mailing list questions@lists.ntp.org https://lists.ntp.org/mailman/listinfo/questions
