Interpreting the Histogram
The histogram can be seen as an indication of how much work a slave clock is doing to stay in sync with
the master clock.
Generally, a stable and accurate clock will show consistently stable offset (with variation in the order of a
few ppm). It means that it is not having to change its offset very much to stay in sync.
Show me
A histogram that shows a distributed range of offsets indicates an unstable clock - it is having to change its
offset significantly, and often, to stay in sync with the master clock. This can be due to overloaded network
links, or poorly-implemented EEE. A device in this state is highly likely to lose sync with the master clock.
