I would like to use something such as Iperf to regularly test bandwidth/throughput (other measures are a bonus) from point to point. Points being windows hosts unless someone knows how to do this from Cisco 3560/70's switches using IP SLA. I do not use Cisco routers.
The catch is that I would like to log either via SNMP or syslog the results. I don't see any way to using Iperf.
