Thanks for the comments, Todd. Regarding the logs -- you can set the log location in ntp.conf (I use an nfs mount so logging data from all the servers is on my data processing system). On my Debian systems, there is a script called (surprisingly) ntp in the /etc/cron.daily directory that does the log pruning. I've modified mine to tweak the number of days logs it keeps, and to remove the gzip stage. One problem is that if you keep lots of days worth of logs and create a long-term plot from it, the program can take a long time to run. It doesn't keep a lot of data in memory, so it's looping through maybe 100 MB of log data. You can also get cases where Grace is unhappy because it's being fed too large a data set (though it will usually plot OK). To address both these problems, I just added a new option that allows averaging the data points down to a smaller number before feeding them to Grace. It makes a modest difference in speed (because it still has to loop through the main log file to pull out the individual server data) but keeps Grace happy and makes the long term plots a bit smoother looking. I plan to upload that version by the end of the weekend.
