STARCAT (STAtiscic Reporting, Collecting and Analysing Tool) is a toolkit to gather statistics out of several sources (for example, rrd-files, logfiles, DBMS,...) and create nice-looking reports out of them using XML-templates.
Cisco Perl Tools contains CIPAT (Cisco IP Accounting aggregator) and ISDN-Reporter (Cisco ISDN call aggregation and reportingtool). [NetProvisioning has moved to its own project page on SF]
