The purpose of cfgstoragemaker is to remotely generate an mrtg config file in order to graph all storage devices (disk, memory and swap) of one or more specific host(s) via snmp.
as you can imagine, it was heavily inspired by cfgmaker.
one of the most important advantages of cfgstoragemaker is that you don't have to install and run mrtg on the servers you want to monitor, everything is done remotely on a distinct and centralized monitoring host. the datas are acquired by snmp.
moreover, you don't have to worry about the list of all the mounted partitions and their size, cfgstoragemaker will do that for you.
