Relatively good resolution. Relative to what? :) Deviation requires you have something to measure against. A “source of truth”. So what are you measuring deviation from?
From a system administration perspective , I want all my systems to be consistent. I’ll say that right == consistently wrong For many purposes. The inconsistency is what causes all manner of hair pulling for me as a system administrator across any meaningful fleet size. Very quickly you run into SSL and LDAP authentication issues. I do frequently run date/time checks to generate the cloud of data points , and I do log NTPD client and server via snmp using librenms . I’m about to dive into netdata graphing as well. I’m using a raspberry pi with gps hat for my master time source. Shortly I’ll be having a total of three systems (two using the same hat , one using the adafruit hat and being a pi2). I’ve got some interest in multiple way comparison and will follow this thread shortly. I’ll blog my setup and post a link. > On Dec 26, 2018, at 10:31, Chris Howard <[email protected]> wrote: > > > > I see the different forms of deviation measurements and they are all > one-to-one comparisons. > > Is there anything to be learned from doing mass data gathering? > > For example, if I had a device of relatively good resolution that would let me > timestamp the events from 100 different clocks, then questions about the > change of the mean of the cloud of events, distance from the mean of > individual > events, etc. could be obtained. > > One of many things I have learned hanging around here is that some > very very smart people have already thought of anything that > might come to me. > > It seems like, if there were a significant number of clocks involved, the mean > of the cloud of events would help cancel out positive and negatives and > particularly > remove the short term randomness ? > > So, has this sort of thing been done? > Why is everything one-to-one only? > > > > _______________________________________________ > time-nuts mailing list -- [email protected] > To unsubscribe, go to > http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com > and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
