Using SNMP for connection metrics

[Mike Green]

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!
