Graphite skips every third point
I launched statsd+graphite+grafana for test. And producing values from console, expect just linear graph. But there are zero values in every third position. I realise all of these tools are widely in use, so it's definitely my mistake. But can't find where exactly.
Here is screenshot of grafana
As you can see every 30s (every third point) is zero. Why?
I do this from shell to increment my counter twice a second:
while :; do
echo "test-service.nreq:1|c" | nc -w1 -u 127.0.0.1 8125
done
I thought there is statd who looses the values due to UDP. But according to log, it doesn't:

Resolved a problem. The problem been in Docker and Mac OS. It seems, there is always some time-skew in Mac OS docker. And due to problem like this statsd sent several values in same 10-second period. Graphite always account latest, and it was zero.
