When generating the statistics and tracking logs from chrony, I see the following headers (along with the accompanying data):
Tracking:
=== Date (UTC), Time, IP Address, St, Freq ppm, Skew ppm, Offset, L, Co, Offset sd, Rem. corr., Root delay, Root disp., Max. error ===
Statistics:
=== Date (UTC), Time, IP Address, Std dev'n, Est offset, Offset sd, Diff freq, Est skew, Stress, Ns, Bs, Nr, Asym ===
For the tracking file, I'm trying to understand what the following mean:
- Co
- Rem. corr.
- Max. error
For the statistics file, I'm trying to understand the following:
- Est offset (vs the regular offset)
- Diff freq
- Stress
- Ns, Bs, Nr, and Asym
I'd appreciate any guidance or links to documentation that explains what these variables represent. Thanks.
I read through the chrony documentation online (https://chrony.tuxfamily.org/faq.html) and found good information on most of the fields in the tracking log; I could not find information on all of them, however. I was also not able to find much information on the header fields in the statistics log.
