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)
