Using Apache2.26 Balancer-Manager effectively

Hi

I have successfuly set up Apache 2.26+a pack of 4 mongrels on a
Wndows 2003 Server.

Looking at the Balancer-Manager,there are certain info displayed for
each mongrel process such as

Worker URL : http://127.0.0.1:9001
Route : 1
Route Redir Factor Set :0
Status : OK
Elected : 237
To :150K

From :1.3M

Apart from Worker URL and Status, what does the rest mean ?

Are there any docs or resources that can explain how to use the
balancer-manager effectively ?
