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

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.
