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
