If you have already opened Google Adsense account, configured and activated the same with Hub Pages, you can just log in your ID. Here you can view under ' Reports' that day's earnings. There is also drop down menu for viewing previous day, that particular month, etc.
There is one more method. You just go to 'my account' and then click on 'Affiliate Settings' under 'earnings'. Here you can view all kind of earnings, whatever you have configured.
Pl. go for details in: http://hubpages.com/community/Track-Individual-Hub...
On top of everything, please be patient for viewing your earnings, since you have just opened your account very recently (just some hours ago). You have to put lot of efforts on writing and creating viewers to your hub. Finally, there should be some interesting clicks on the advts. which obviously creates your earnings. All these things will take a minimum time at least.
My best wishes for your early earnings! Live Long Life and write more here!!
