Each stats file contains accumulated data and statistics.
Note: The contents of this file depend on the current PTP mode and position of the clock in the PTP hierarchy. A stats file exists for each sync module and also for the server system clock.
The following table describes the values in a typical stats file:
| Name | Description |
|---|---|
| offset-from-master (ns) | Mean, min and max values are accumulated for these statistics. The number of samples taken during each period is recorded as is the start/end time of each sample period. |
| one-way-delay (ns) | |
| freq-adjustment-ppb (ppb) | |
| synchronized |
The stats file retains accumulated counts of each PTP message type sent or received from the server. The statistics file also records the number of PTP packets sent of received without being hardware timestamped. The number of samples taken during each period is recorded, as is the start/end time of each sample period. |
