[syslog-ng] Syslog-ng Statistics

Have anyone written any statistics package for syslog-ng? Id be interested in anything that would show information like number of messages received since last stats(XXXX), mb of messages received / sec, messages per prio etc etc etc :) Anything would be useful! Im looking for something similar to the output that you can get from bind and nsd for making graphs Best Regards Kenneth Gullberg
