This is gmond python module that allows SNMP polling of network switches to get interface packet and throughput metrics. * It works for Foundry NetIrons, and probably for any other SNMP enabled switch. * It requires pysnmp (available in debian repositorys) * Handles polling multiple switches from a single gmond. * Spoofs the switch hostname, so each switch shows up separately in ganglia If you're handling a large number of metrics, you may wish to set your sysctl settings as below: net.core.rmem_max=104857600 net.core.rmem_default=104857600 vm.dirty_ratio=100 vm.dirty_background_ratio=100 vm.dirty_expire_centisecs=720000
