It was fun to try out this software. It lacks some features in the interface though... With some more automatic processing and UI improvements, it could definitely be a low-end rival to splunk, but right now it can only do a standard search on custom attributes or whole text (not with a proper full-text index though) or show stuff "around that message". That means basics only.<p>But with the development happening all the time, it's definitely a project worth keeping in bookmarks. If it can get some of the features available in octopussy without looking just as fugly, I'm in :)
