Getting CPU/Memory information and graph structure of a topology?

[hilfi alkaff]

Hi,

I am currently trying to develop a scheduler following
http://xumingming.sinaapp.com/885/twitter-storm-how-to-develop-a-pluggable-scheduler/but
I could not find ways to get the aforementioned information from
inside
the scheduler. Is there anything that I miss?

Thanks
