       DESCRIPTION
           "This data type is used to model textual information
           in some character set.  A network management station
           should use a local algorithm to determine which
           character set is in use and how it should be
           displayed.  Note that this character set may be
           encoded with more than one octet per symbol, but will
           most often be NVT ASCII. When a size clause is
           specified for an object of this type, the size refers
           to the length in octets, not the number of symbols."

           sysUpTime in the SNMPv2-MIB [RFC1907] because

   hrStorageTable OBJECT-TYPE
       SYNTAX     SEQUENCE OF HrStorageEntry
       MAX-ACCESS not-accessible
       STATUS     current
       DESCRIPTION
           "The (conceptual) table of logical storage areas on
           the host.

           An entry shall be placed in the storage table for each
           logical area of storage that is allocated and has
           fixed resource limits.  The amount of storage
           represented in an entity is the amount actually usable
           by the requesting entity, and excludes loss due to
           formatting or file system reference information.

           These entries are associated with logical storage
           areas, as might be seen by an application, rather than
           physical storage entities which are typically seen by
           an operating system.  Storage such as tapes and
           floppies without file systems on them are typically
           not allocated in chunks by the operating system to
           requesting applications, and therefore shouldn't
           appear in this table.  Examples of valid storage for
           this table include disk partitions, file systems, ram
           (for some architectures this is further segmented into
           regular memory, extended memory, and so on), backing
           store for virtual memory (`swap space').

           This table is intended to be a useful diagnostic for
           `out of memory' and `out of buffers' types of
           failures.  In addition, it can be a useful performance
           monitoring tool for tracking memory, disk, or buffer
           usage."
