snmpdf - display disk space usage on a network entity via SNMP
snmpdf [COMMON OPTIONS] [-Cu] AGENT
snmpdf is simply a networked verison of the typical df command. It
checks the disk space on the remote machine by examining the HOST-
RESOURCES-MIBs hrStorageTable or the UCD-SNMP-MIBs 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 con
sist 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 snmpcmd(1) manual page for a full
list of the possible formats for AGENT.
See the snmpd.conf(5) manual page on setting up the dskTable using the
disk directive in the snmpd.conf file.
Please see snmpcmd(1) for a list of possible values for COMMON
OPTIONS as well as their descriptions.
-Cu Forces the command to use dskTable in mib UCD-SNMP-MIB instead
of the default to determine the storage information. Generally,
the default use of hrStorageTable in mib HOST-RESOURCES-MIB is
preferred because it typically contains more information.
