2 troubling concerns: 1) NTP's 'rawstats' file fails to write (or even be created). Oddly, peerstats, loopstats, clockstats, and sysstats all write and update as expected. Please see my ntp.conf file at the bottom of this message. I don't believe that the config file is the problem, but maybe I'm wrong.
2) Peerstats updates in a bizarre fashion. If the system time is close to my reference time (GPS/PPS), then it updates every 16 seconds as indicated by the 'poll' field that I see with the 'ntpq -p' command. However when I manually fudge the system time by X minutes using the 'date' command, peerstats will not update itself for X minutes. Once X minutes have passed, the offset is sub-millisecond, and peerstats will resume logging its results ever 16 seconds. My goal is to monitor the offset after I manually fudge the system time, to see the rate that NTP adjusts system time. Oddly, peerstats will not update if I fudge the system time by -5 minutes, and rawstats fails to write at all. At the very least, this gives me a chance to document my thoughts. Any opinions on this behavior are greatly appreciated. /etc/ntp.conf: *********************************************************** ftfile /var/log/ntpstats/drift logfile /var/log/ntpstats/xntpd statsdir /var/log/ntpstats/ enable stats statistics loopstats peerstats clockstats sysstats rawstats #statistics rawstats filegen rawstats file rawstats1 type dat enable filegen loopstats file loopstats type day enable filegen peerstats file peerstats type day enable filegen clockstats file clockstats type day enable filegen sysstats file sysstats type day enable filegen rawstats file rawstats type day enable enable kernel server 127.127.1.0 # Local clock fudge 127.127.1.0 stratum 8 # Local stratum server 127.127.30.0 prefer # GPS clock ************************************************************ _______________________________________________ pool mailing list [email protected] http://lists.ntp.org/listinfo/pool
