I checked it and it was indeed set to 50. I changed it to inf and I restarted nav and carbon.
Now I can see many new databases being created. Thank you very much for such swift response.
It's a shame, that carbon ignores exceeding creation requests silently (I even checked the creates.log for new databases)

After recreating whisper databases I can see some of the graphs. Now I have another problém - not all statistics are collected! I checked graphite and it displays only few of them. The nav systém have ran for a day now, so I would expect, that it is enough time to collect all informations.
In the screenshot (made from graphite webinterface) you can see various collected statistics - they are not even the same for various ports.
Did you configure Carbon's "MAX_CREATES_PER_MINUTE", as per. NAV's install instructions?
Carbon's default limit is maximum 50 new Whisper files created per minute; when more than 50 metrics are received within a 1 minute window, only the 50 first will be created by Carbon, the rest will be silently ignored.
Depending on the number of devices you have seeded into NAV, a setting of 50 may cause Carbon to take from many hours to several days to create Whisper files for all the metrics that NAV is throwing at it.
