site usage analysis report programmatically

Question

I have 1000 sites in my site collection and I want to get usage analysis report from each one of them(sites not sitecollection). Ofcourse I will not go manually and get this information. So i was thinking of doing it programmatically

Basically I need information about these two things

1) Requests and queries in the last day and the last 30 days. 2) Average number of requests per day over the last 30 days.

If anyone is having idea how to achieve this?

Note: I saw the Spusagereporttype which gives the report based on user,Os,browser..but I want the report for above mentioned points which we can see when we go to site and sitesettings ->siteusage report...so how to access that object model....
