Hello, I am using chrony 3.2 on RHEL 7.6. I was trying to find out why my clock seemed to be out of sync with the NTP server despite chrony running and the 1 NTP server I had configured was online. I turned on "log measurements" which in the chrony.conf man page says:
measurements This option is identical to the rawmeasurements option, except it logs only valid measurements from synchronised sources, i.e. measurements which passed the RFC 5905 tests 1 through 7. This can be useful for producing graphs of the source’s performance. This specifically says "only valid measurements from synchronised sources", but It was still showing log lines for the source. When I looked at `chrony sources -v` it listed the source state as "?", which is quite confusing because the source is not actually "unreachable". I tracked the issue down to the source reporting a root dispersion of 5.4 seconds. If I increase the "maxdistance" then chrony shows the source as online. Why does chrony show the source as " '?' = unreachable", instead of like "'x' = time may be in error"? Why are there lines in the measurements file when the source is not synchronised? My servers(doesn't include the NTP server) will be together on a LAN, without a gateway to the internet. The NTP server is provided by someone else, and I am not sure if it will be synced with an external source. Can someone provide some insight/recommendations here please? Should I just leave the maxdistance at 16.0? I am kind of inclined to blame the person managing the NTP server; they should probably sync its time regularly some how, either manually or from an external source (over internet or GPS, whatever).
