For number 2 you need the remote servers to "broadcast" various
load information (CPU usage, memory usage, load average, etc) and
somehow have the load balancer "listen" on that broadcast to obtain
that info.

part #2 sounds more like the kind of a task you would want to use at
least an external process, if not a separate physical machine for.
Basically, you are looking for an intelligent load balancer, correct?

Subject: Re: Howto implement a new algorithm scheduler in
mod_proxy_balancer
Sounds like 2 questions there: (1) is there anyway to create some sort
of scheduler that does periodic functions and (2) how to obtain
external
server info (like CPU, etc...).
Re #1: Under 2.2, there is a monitor hook, but it is pretty limited.
Best thing is to create an external process which runs separately and
adjusts shared memory data.
Re #2: It ain't trivial.

hi,
I saw the link.
So one more question.
Can I development a scheduler that receive datas from cluster.
For example:
If machine1 == overloaded CPU
sent requisition to machine2
How to do scheduler (via programming) obtain information of CPU from
others machines ??
Thank You

It's not yet in the stable branch 2.2, but you can find it in the
trunk:
http://svn.apache.org/viewvc/httpd/httpd/trunk/modules/proxy/
examples/
to watch it with a browser, or
http://svn.apache.org/repos/asf/httpd/httpd/trunk/modules/proxy/

as a URL to check it out via svn.

Not sure what the question is... is it how to test your algo or
how
to implement it?
There is a quick-and-dirty example submodule in trunk (under
modules/
proxy/examples)
that give some basic overview.

Hi,
I wanted implement a new algorithm scheduler to
mod_proxy_balancer.
I built a new algorithm and want test in apache2.
Thank you
