However, what about the .count metric also sent for timers? Each sample contains the count of occurences per flush interval, so you want these samples summed-up, not averaged!

According to me correct solution will be pass actual sampling rate to central statsd servet for .count metric of timers.

foo:8|ms
foo:5|ms
foo:3|ms

should becomes: (if given sampling rate is 0.1)
foo:8|ms:5|ms:3|[email protected]

what you think ? I could have tried this but I don't have that much knowledge of node js language.
