+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)
+  * Handles polling multiple switches from a single gmond.
+  * Spoofs the switch hostname, so each switch shows up separately in ganglia
+
+## DEPENDS
+  * python pysnmp
+
+## USAGE
+  * 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 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

+This is a GMOND Python Module that gets metrics from EMC RecoverPoint replication appliances.
+
+## DEPENDS
+  * python YAML
+  * paramiko modules
+  * ssh access to the recoverpoint appliance (paramiko can use ssh keys if required)
+
+## USAGE
+  * Save the recoverpoint.pyconf into /etc/ganglia/conf.d directory and update the management IP and sitenames (the sitenames have been lowercase'd)
+  * Save the recoverpoint.py into your ganglia python module dir eg: /usr/lib/ganglia/python_modules.  Update the username/passwords if necessary.
+  * Restart gmond and a "recoverpoint" host should appear in ganglia.
