[Lustre-discuss] lustre dstat plugin

[Brock Palen]

I have wrote a lustre dstat plugin.  You can find it on my blog:

http://www.mlds-networks.com/index.php/component/option,com_mojo/ 
Itemid,29/p,31/

It only works on clients, and has not been tested on multiple mounts,  
Its very simple just reads /proc/

Example:

dstat -a -M lustre

----total-cpu-usage---- -dsk/total- -net/total- ---paging-- ---
