is simply a networked verison of the typical df command. It
checks the disk space on the remote machine by examining the
HOST-RESOURCES-MIB’s hrStorageTable or the UCD-SNMP-MIB’s dskTable.
By default, the hrStorageTable is preferred as it typically contains
more information. However, the -Cu argument can be passed to snmpdf
to force the usage of the dskTable.
AGENT identifies a target SNMP agent, which is instrumented
to monitor the gievn objects. At its simplest, the AGENT
specification will consist of a hostname or an IPv4
address. In this situation, the command will attempt
communication with the agent, using UDP/IPv4 to port 161
of the given target host. See the
manual page for a full list of the possible formats for AGENT.
