4.6.2 Logs
VersaSync maintains different types of event logs (see below) to allow for traceability, and for
record keeping. Should you ever require technical support from Spectracom, you may be
asked for a copy of your logs to facilitate remote diagnosis.
Logs stored internally are being kept automatically, while the storage of log files in a remote
location has to be set up by the user.
For each type of log, four 75KB files are maintained internally on a revolving basis, i.e. the
oldest file will be overwritten, as soon as all four files have filled up with event data. The life
expectancy of a log file depends on the amount of data accumulating over time: Some types of
logs will fill up within days, while others can take months until they have reached their max-
imum storage capacity.
You can delete logs at any time, see "Clearing All Logs" on page220.
4.6.2.1 Types of Logs
VersaSync generates log files for the following event categories:
Alarms Log
Displays log entries for the Timing System, for example:
The Unit has Rebooted: VersaSync was either rebooted or power cycled.
In Holdover: Input references were available, but all input references have since been
lost. If the references are not restored before the Holdover period expires, time sync will
be lost.
No longer in Holdover: Input references were lost at one point (or declared not valid), but
have since been restored OR the Input references were not restored before the Holdover
period expired (Time Sync alarm is asserted).
In Sync: VersaSync is synchronized to its selected Time and 1PPS reference inputs.
