If you think you found an issue and would like to report it we ask that you consider the following things before submitting an issue:
First make sure that it truly is an issue. If Cacti does not behave the way you expected look at the documentation, mailing lists, and forums to see if this is a known behavior. If you are unsure ask on the forums (forums.cacti.net) or ask the users mailing list (email@example.com).
Once you have established that it is an issue the most important thing you can do is come up with a description of the issue and an explanation of how to reproduce it. Screen shots and debug information are always welcomed.
When you do write up the issue report do not include a prose description of what you did to make the issue occur. Instead give a detailed description of the actions you took to cause the issue. Include the buttons, links, inputed text, changed items, actions, etc.
Once you have your full description and actions you took that reproduce the issue, don't forget some of the most important information:
Now you are ready to write a issue report. Start out with a clear description of the issue - how you expect Cacti to behave and how it is behaving. While the issue maybe obvious to you it may not be obvious to someone else.
Happy issue reporting!
