sfptpd generates state and statistical data in files in the
/var/lib/sfptpd directory. These files are
automatically generated whenever
sfptpd is running. No additional
configuration is required.
# ls /var/lib/sfptpd freq-correction-000f:53ff:fe11:2233 freq-correction-000f:53ff:fe44:5566 freq-correction-system interfaces ptp-nodes state-000f:53ff:fe44:5566 state-ntp state-ptp1 state-system stats-000f:53ff:fe44:5566 stats-000f:53ff:fe44:5566.json stats-ntp stats-ntp.json stats-ptp1 stats-ptp1.json stats-system stats-system.json topology version
Note: The stats-system file is only generated when the system clock is being synchronized to another clock in the host and is controlled by a local clock servo process. When running an NTP fallback configuration the system clock is synchronized by NTP, therefore no stats-system file is created.
