[Click] Click Footprint

[Eddie Kohler]

Hi Alastair,

If you're talking about kernel Click, there are a couple places you  
can look.  "lsmod" will tell you the size of the binary module.   
Then /click/meminfo will tell you the number of blocks of memory that  
have been allocated so far, but not the size.  If you want size too  
that should be pretty easy to add; grep in linuxmodule/module.cc and  
lib/glue.cc for references to the click_outstanding_news variable to  
get a sense for how we keep track of it; send a patch when you get it  
working.  It is hard to tell how many *packets* are stored within  
Click at any given moment; /proc/slabinfo or something similar will  
tell you how many packets the whole Linux kernel has outstanding.
