We would like to change the wlc scheduling algorithm to take into account,
CPU loads, memory usages, and network load of the real servers.

The approach is to periodically cheek these parameters, and update the
weight
assigned to each real server, according to a given function.

A first such approach has been made by Jeremy Kerr, that take into account
CPU loads, in LVS.

Yes,  I have to include monitoring tools in the Piranha software. This is
why
I am looking to the source files in order to have a global comprehensive
view
of the software.

So, could you please be more accurate ?. In particular, about the relation
between the
different components of the software.

Thanks in advance,
