NAME

   snmpdf - display disk space usage on a network entity via SNMP

SYNOPSIS

   snmpdf [COMMON OPTIONS] [-Cu] [-Ch] AGENT

DESCRIPTION

   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.

   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 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.

OPTIONS

   COMMON OPTIONS
           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.

   -Ch     Print sizes in human readable format (i.e. MiB, GiB, TiB)

   -CH     Print sizes in human readable SI format (i.e. MB, GB, TB)
