New question #233781 on Graphite: https://answers.launchpad.net/graphite/+question/233781
Hello, Perhaps I'm quite stupid but i can't configure the aggregation. Your help is welcome :) My program sends 13 metrics each 30 seconds and I want to aggregate it in one minute. To do this I use the storage-schemas.conf and storage-agregation.conf files (see at the end of this post). To test my configuration I send 2 metrics and 2 others 30 second after. metric1.Count 5050 1375974000 metric2.Temps 67 1375974000 metric1.Count 5050 1375974030 metric2.Temps 67 1375974030 I close the TCP connection at the end of the set (metric1 and metric2). Graphite create two tables: 09/08/2013 14:21:39 :: [creates] new metric APP.metric2.Temps matched schema APP 09/08/2013 14:21:39 :: [creates] new metric APP.metric2.Temps matched aggregation schema Temps 09/08/2013 14:21:39 :: [creates] creating database file /opt/graphite/storage/whisper/APP/metric2/Temps.wsp (archive=[(60, 44640)] xff=0.0 agg=average) 09/08/2013 14:21:39 :: [creates] new metric APP.metric1.Count matched schema APP 09/08/2013 14:21:39 :: [creates] new metric APP.metric1.Count matched aggregation schema Count 09/08/2013 14:21:39 :: [creates] creating database file /opt/graphite/storage/whisper/APP/metric1/Count.wsp (archive=[(60, 44640)] xff=0.0 agg=sum) As we can see the schema match to the configuration file and the good aggregation method is used. I can confirm this with whisper-info.py. I watch the result with graphite-web and metic1.Count is always at 5050 and not 10100. I don't understand why aggregation doesn't work.
