Graphite

Graphite doesn't create all graphs

Asked by Wawrzyniec Niewodniczański

I use your python client example to feed graphite with some data. Some data means around 2000 metrics.

In listener.log I see traces of connection:
19/10/2012 13:35:01 :: MetricLineReceiver connection with 127.0.0.1:39068 established
19/10/2012 13:35:12 :: MetricLineReceiver connection with 127.0.0.1:39068 closed cleanly

I don't see any errors, but not all metrics are created. Indeed I see only 38 "creating database" entries in creates.log during first connection and another 49 during second.

OS metrics are fine (low load).

What might be a problem? I feed socket too quick?

It seems that after created the value adding is fine.

So is graph creating heavy process?

Yes, creating a file is a I/O intensive operation. There is an option in carbon.conf called "MAX_CREATES_PER_MIN"
That is the number of new files that will be created each minute.
If you have a fast system, you can increase this number to 100 or maybe 150 to speed things up.

Can you help with this problem?
