Interpretation of PTP4L and PHC2SYS syslog records

by YitzikC   Last Updated November 14, 2017 19:00 PM

I'm using the ptp4l and phc4sys services to syncronize the clocks of my Centos 7.4 servers to a central PTP source. The services regularly write syslog records like the one below. I haven't found any documentation explaining what each field here means, and what the units are. I'd appreciate any leads!

Nov 14 17:07:26 stg1 ptp4l: [718277.895] rms   74 max   99 freq  +8760 +/-  84 delay   535 +/-   0
Nov 14 17:07:27 stg1 phc2sys: [718278.105] phc offset       -62 s2 freq  +14460 delay   2117
