Hi, I am using ntpv4.2.0 and have a question about the system statistics interpretation on my NTP server.
The ntp page on monitoring options lists 11 'system stat' fields as follows. http://www.eecis.udel.edu/~mills/ntp/html/monopt.html MJD date time past midnight time since restart packets received last hour server packets received last hour current version packets last hour previous version packets last hour access denied packets last hour bad length or format packets last hour bad authentication packets last hour rate exceeded packets last hour A sample of my daily filegen output is as follows (12 fields): 54493 514.622 117 12 3 12 0 0 0 0 0 0 54493 4118.319 118 14 2 14 0 0 0 0 0 0 54493 7722.012 119 13 3 13 0 0 0 0 0 0 It is critical for me to understand the meaning of each of the stats to properly monitor my NTP deployment. Can someone please point me to more detailed descriptions or maybe just confirm and comment on my guesses below. My interpretation of the stats meaning (for my 1st line output listed above) is as below: 54493 - MJD date 514.622 - UTC time past midnight in seconds 117 - time since restart (in hours? or is this just a record count?) 12 - packets received last hour (NTP req packets from clients last hour) 3 - Server Packets received last hour (packets from other servers??) 12 - current version packets last hour (NTP req packets from clients using same version of NTP) 0 - previous version packets last hour 0 - access denied packets last hour (not allowed to synchronize with me???) 0 - bad length or format packets last hour 0 - bad authentication packets last hour (bad MD5 check??) 0 - rate exceeded packets last hour (exceeded the min poll rate or some such?) 0 - extra field not described on web???? Most critical for me is that I understand that "packets received last hour" is really a count of NTP requests from clients. I want to use this to get a rough idea of the load on my server to use for scaling and monitoring. thanks, Steve _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
