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)
