As my personal servers are running Ubuntu I opted for the source install, however for some reason Urchin sees it as Fedora? It works, but it's a very odd thing to report...
As the software is commercial you have to get a license. Fortunately once it's installed you can simply follow the wizard to get your license key and have the data passed back to your server.
You can then go about setting up "profiles". If you're familiar with Google Analytics then most of the jargon is almost identical.
The key difference is that Urchin can parse physical log files both local and remote ie. on the same server or anywhere else (as long as they can be accessed via FTP, HTTP or HTTPS). Unfortunately it doesn't seem to offer support for SCP or Rsync, which would be very handy.
You can easily setup a new site profile by following the online wizard and choose multiple log sources.
The reporting interface is very similar to the old Analytics one pre-upgrade. You can choose from 3 different views, depending on which type of report you want to see.
Nothing too exciting there.
Where it gets interesting is in the speed of the interface. As it's running on one of my machines on our network I don't have to contend with the rest of the internet, so it's way faster.
The simpler UI renders different views a lot faster as well.
As it's working on local log files (my config choice) it can also give me bandwidth usage which is kind of useful. (I didn't realise GoogleBot had used nearly 7 Gigs so far this month on one site!)
The other really cool thing is the update frequency.
One of the major downsides of Analytics, especially since it went "free" is that the data is nowhere near "real time".
With Urchin you can get updates as often as you want.
If you're a stats junky you could choose to have it update every hour if you want. Plus you can choose which minute of the hour (handy if you have multiple profiles on the one machine and don't want CPU meltdown!)
I'll try and setup a few more profiles, schedule updates etc., and see how it handles things.
So far I like it, though some of the interface options are a bit counter-intuitive. Fortunately the contextual help / documentation is pretty clear, so I haven't run into any "show stoppers" just yet!
