The flush function will now be called every 2 seconds.  But there will only be things to flush every 10 seconds - after a bucket boundary.  so 4 out of every 5 logs will say "flushing 0 metrics".  So in order to get useful information, we need to log 5 times (10 lines) every time we log.

I tried to adjust the numbers so that the log will be the same size - logging less often, but more lines each time it logs.  The FLUSH_LOGGING_INITIAL at 60 will report in 12 non-zero metric flushes.  The FLUSH_LOGGING_COUNT at 5 will report 1 non-zero metric flush
