.SH NAME
snmpdf - display disk space usage on a network entity via SNMP
.SH SYNOPSIS
.B snmpdf
[COMMON OPTIONS] [\-Cu] [\-Ch] AGENT
.SH DESCRIPTION
.B snmpdf
is simply a networked version 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.
.PP
AGENT identifies a target SNMP agent, which is instrumented
to monitor the given 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
.I snmpcmd(1)
manual page for a full list of the possible formats for AGENT.
.PP
See the
.I snmpd.conf(5)
manual page on setting up the dskTable using the 
.I disk
directive in the snmpd.conf file.

.B \-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.
.TP
.B \-Ch
Print sizes in human readable format (i.e. MiB, GiB, TiB)
.TP
.B \-CH
Print sizes in human readable SI format (i.e. MB, GB, TB)
