@ustcweizhou is just calling the wrapper for the system in millis, which
was added to the profiler. For the remaining cases, the nano time will be used
(getDuration()).
His use of getDurationInMillis() looks good because inside the method I
convert the nanoseconds to milliseconds:
(stopTickNanoSeconds - startTickNanoSeconds) /
(long)Math.pow(MILLIS_FACTOR, EXPONENT);
LGTM :+1:

> We got a lot of debug message in management-server.log every 1.5 seconds.
> The cluster.heartbeat.interval is set to 1500 by default. As it was not
> changed after its first commit, so I think it is 1500 ms.
> However, The durations are less than 10ms actually.
