The document discusses OpenNMS reporting enhancements. It describes the current status of reporting in OpenNMS, including performance data stored in RRD files and other data in SQL databases. It then discusses why a reporting engine would be useful, including easier customized reports, scheduling, and deployment. The document outlines how the OpenNMS reporting engine would work using JasperServer and its web service API to generate reports from OpenNMS data. Finally, it provides an example report and discusses alternatives to JasperServer before concluding with future perspectives.

14. Conclusion and
perspectives
• It´s the entering wedge
• It would be nice to put the basic reporting
stuff to the OpenNMS webapplication
• Provide a platform for reporting
• Create report-packages in the community
• Cool stuff for reporting in the pipeline
