I am currently running a trial version of Opsview Enterprise (latest version of course) on a VM Ubuntu Server v12.04.
Installed the reports module as detailed in the documentation although whenever I click on any of the items (Repository, Analysis views, Reports, etc) I receive a wonderful Tomcat 404 :)
I've posted an example of the text below. Not much else to say I suppose.
Please let me know of any text/logs you may require and I will have them posted to you ASAP.
