hi,
Presently I collect CPU, Memory in USE, and Network traffic statics from
my windows terminal server "real servers" via snmp. I toss this
information into an rrd database for makeing pretty graphs along with
usage parsed from lvs stats. Finaly I take the CPU and Memory stats and
use them to adjust my weight tables. My script for doing this is still in
its infancy as I am getting stuff ready for this fall term, but it should
be fun to see how it all works out.
the script is in its infancy. I still need to finish up lots in it, and
more refined decision makeing. Add more output. Add in keepalive stuff
before snmp stuff so snmp stuff doesnt barf. etc etc etc its just a rough
example ;)

Hello -
I've seen many projects in which SNMP metrics have been used as a heartbeat,
but I was wondering if there was any implementation in which information
such as CPU/memory usage on the realserver was used as a decision factor for
load balancing.
I know this may be overreaching for something kernel-integrated, but wanted
to know if there were any LVS-associated projects that have tried this.
Thanks much in advance!
