If you have multiple sites or multiple directories in your site for different subjects and you have placed Adsense codes in your site, I am sure you would like to know: (a) from which site or directory you are earning the most / least, (b) which Adsense ads are being clicked and (c) from which page?
CREATE CHANNELS FOR EACH SITE
To get separate stats for each site / section / directory / page with Adsense, you need to create channels for each one. Create a channel with a relevant name and generate a code for that channel. Paste that particular Adsense code to the concerned pages / sites.
GET CHANNEL STATS IN REAL TIME
Google now provides Channel Data in real time. Earlier, it used to provide data for '2 days before'. Follow the procedure mentioned below :

1. From 'Date Range' drop down menu, select 'today'.
2. Check the radio button : Group data by 'Channel'.
3. On the right hand panel, check the radio button 'Channel data'.
4. Click on 'Select ALL' at the bottom of channel list.
5. Click on 'Display Report'.

Now you get the seggregated report for clicks generated for each channel.
WHICH ADS ARE BEING CLICKED AND FROM WHICH PAGE?
It is very important to know that which pages / sites are generating good Adsense revenue and which are not. We can work upon those poorly performing pages. If we can get to know about which ads are being clicked, that would make us feel more informed for many obvious reasons.
Currently Google does not provide this data. But you can still get it from a very nice and detailed free web stat service, Add Free Stats.
Add Free Stats provides a very detailed web stats which satisfies most webmasters. You may open a free account at : http://www5.addfreestats.com, get the code and paste it at the bottom of each of your pages.
Make sure that in 'Your Account' section you mark 'Yes' for 'Exit link tracking'.
Now check your stats at Add Free Stats, and you will find a "A" icon beside the visitors' ip. That means that visitor has clicked on an Adsense code. Place your mouse over the icon, and you can see which ad has been clicked.
You can also generate a separate report of pages that have generated Adsense click. Select 'Exit Links/Adsense' from the drop down menu marked as 'Pages'. Here you get a folder icon named Adsense, the number of Adsense clicks etc. Click on the Adsense folder icon and you get the number of Adsense clicks on each page and which ads are clicked on that page. Click on the 'hour glass' icon and you get the CTR, PV too for each page.
I am no way connected to Add Free Stats. I am just a happy user. Any webmaster working seriously towards Adsense earning, must have this tool.
