How graphite handle same second hits?

Asked by julien

hi,

Let's say carbon receives these 3 identical hits

live.search.hit 1 1409831470
live.search.hit 1 1409831470
live.search.hit 1 1409831470

Will I see in graphite live.search.hit = 3 at this second?

Hi julien,

No, for same timestamp metrics will be overwritten. And not only for same timestamp, but for all timestamps matching with lowest retention. I.e. if you have retention = 60 s there's no need to send metrics more often than once per 60 s - last one will overwrite previous ones from same minute.
Thing what are you looking for is calling statsd - it has counters, timers etc. Check that link for details - http://blog.pkhamre.com/2012/07/24/understanding-statsd-and-graphite/
