Brocade FibreChannel This is gmond python module that allows SNMP polling of Fibrechannel switches to get interface packet and throughput metrics.

• It works for Brocade FC switches, and probably for any other SNMP enabled switch.
• It requires pysnmp (available in debian repositorys)
• Now executes SNMP queries as a separate thread
• Handles polling multiple switches from a single gmond.
• Spoofs the switch hostname, so each switch shows up separately in ganglia

• python pysnmp

• Save the fibrechannel.pyconf into directory and update the switch(s) name & IP's
• Save the fibrechannel.py into your ganglia python module dir eg: /usr/lib/ganglia/python_modules
• Update SNMP community / ports if necessary
• If FC metrics aren't appearing, increase your net.core.rmem_max and default 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
