Sastragraph is an IP accounting package used for monitoring interfaces on routers via SNMP. It makes logfiles with traffic reports on a daily basis, and produces graphics by using rrdtool. It has the ability to display dynamically generated graphics and daily traffic statistics via CGI script.
Release Notes: The DS in rrd files was changed from COUNTER to ABSOLUTE. Files with traffic statistics are now generated. Logging to syslog is now done. A CGI interface for checking date to date traffic statistics was added (from sasacct). Compatibility with the sasacct package was added in order to produce a full accounting system.
