Couriergraph - a RRDtool frontend for Postfix queue-statistics

Couriergraph is a very simple mail statistics RRDtool frontend for Postfix that produces daily, weekly, monthly and yearly graphs of Courier's POP3, IMAP, POP3s and IMAPs logins.

Download it New version: 02/02/2006

Changes:
* Fixed regexp for the logs
* Now we have only one graph; POP and IMAP are drawn into the same window,
  and POP/SSL and IMAP/SSL are "stacked" areas on top of the normal POP and
  IMAP graphs.
* Removed unneeded variables and functions

Couriergraph Mini-FAQ

How is it possible that in the day graph I see a maximum of 3 msg/min and the peak only tops at 0.75 msg/min?

The drawed value in the graph is a "rate": queuegraph collects the number of queuefiles every minute and rrdtool does "consolidate" the data for the graph being draw. For the first graph the consolidation is done on eight minutes, which means that if three queuefiles were found in eight minutes, the value would be 0.375 messages / minute.
