Samir,

I find this query useful...

      select  first_time,  
              mb,  
              mb - (avg(mb) over ()) dev_from_avg  
      from    (select  trunc(first_time) first_time,  
               sum(blocks*block_size)/1048576 mb  
               from    v$archived_log  
               group by trunc(first_time))  
      order by first_time;  

Hope this helps....

-Tim
