Dear DRBD,

I would like to request a feature for DRBD.  I would be interested in 
showing the data rate sent over the network to the other host in 
/proc/drbd.  This would enable me to monitor bottlenecks and predict 
limitations easily.

I am interested in knowing whether this is the sort of feature it would 
be possible for a user like my self with a few years C experience to add 
my self?  If so, whether any user might give me a pointer or two?

For instance, keeping an array of the last 15 minutes, holding a total 
of data transfer in and out, so that a 1-minute, 5-minute and 15-minute 
rate could be displayed, with the array rotated every new minute.

Please also let me know if this is a really bad idea!

Regards,

Ben.

PS, another feature that would be very useful for me is another version 
of /proc/drbd showing output as XML, say /proc/drbd_xml.  Then my self 
or other users could program our own extensions with ease.  A good DTD 
with comments could aid users tracking problems.  Again let me know if 
this is a bad idea!
