--
-- User History Collection Group (usrHistory)
--
-- The usrHistory group combines mechanisms seen in the alarm and
-- history groups to provide user-specified history collection,
-- utilizing two additional control tables and one additional data
-- table. This function has traditionally been done by NMS
-- applications, via periodic polling.  The usrHistory group allows
-- this task to be offloaded to an RMON probe.
--
-- Data (an ASN.1 INTEGER based object) is collected in the same
-- manner as any history data table (e.g. etherHistoryTable) except
-- that the user specifies the MIB instances to be collected. Objects
-- are collected in bucket-groups, with the intent that all MIB
-- instances in the same bucket-group are collected as atomically as
-- possible by the RMON probe.
--
-- The usrHistoryControlTable is a one-dimensional read-create table.
-- Each row configures a collection of user history buckets, much
-- the same as a historyControlEntry, except that the creation of a
-- row in this table will cause one or more associated instances in
-- the usrHistoryObjectTable to be created. The user specifies the
-- number of bucket elements (rows in the usrHistoryObjectTable)
-- requested, as well as the number of buckets requested.
--
-- The usrHistoryObjectTable is a 2-d read-write table.
-- Each row configures a single MIB instance to be collected.
-- All rows with the same major index constitute a bucket-group.
--
-- The usrHistoryTable is a 3-d read-only table containing
-- the data of associated usrHistoryControlEntries. Each
-- entry represents the value of a single MIB instance
-- during a specific sampling interval (or the rate of
-- change during the interval).
--
-- A sample value is stored in two objects - an absolute value and
-- a status object. This allows numbers from -(2G-1) to +4G to be
-- stored.  The status object also indicates whether a sample is
-- valid. This allows data collection to continue if periodic
-- retrieval of a particular instance fails for any reason.
--
-- Row Creation Order Relationships
--

-- The static nature of the usrHistoryObjectTable creates
-- some row creation/modification issues. The rows in this
-- table need to be set before the associated
-- usrHistoryControlEntry can be activated.
--
-- Note that the usrHistoryObject entries associated with a
-- particular usrHistoryControlEntry are not required to
-- be active before the control entry is activated. However,
-- the usrHistory data entries associated with an inactive
-- usrHistoryObject entry will be inactive (i.e.
-- usrHistoryValStatus == valueNotAvailable).

        When the associated usrHistoryControlBucketsRequested

        object is created or modified, the probe should set
        this object as closely to the requested value as is
        possible for the particular  probe implementation and
        available resources.  The probe must not lower this
        value except as a result of a modification to the associated
        usrHistoryControlBucketsRequested object.

        The associated usrHistoryControlBucketsRequested object
        should be set before or at the same time as this object
        to allow the probe to accurately estimate the resources
        required for this usrHistoryControlEntry.

        There will be times when the actual number of buckets
        associated with this entry is less than the value of
        this object.  In this case, at the end of each sampling
        interval, a new bucket will be added to the usrHistoryTable.

        When the number of buckets reaches the value of this object
        and a new bucket is to be added to the usrHistoryTable,
        the oldest bucket associated with this usrHistoryControlEntry
        shall be deleted by the agent so that the new bucket can be
        added.

        When the value of this object changes to a value less than
        the current value, entries are deleted from the
        usrHistoryTable associated with this usrHistoryControlEntry.
        Enough of the oldest of these entries shall be deleted by the
        agent so that their number remains less than or equal to the
        new value of this object.

        When the value of this object changes to a value greater
        than the current value, the number of associated usrHistory
        entries may be allowed to grow."

    STATUS current
    DESCRIPTION
        "This data type is used to communicate with a modem or a

        remote device through the serial interface.  Commands are
        represented as two character sequences beginning with
        the `^' character.

        The following commands are recognized by the device (note
        that command characters are case sensitive):

           ^s  Send string that follows which is terminated by the
               next command or the end of string.
           ^c  Delay for the number of seconds that follows.  Toss
               out any data received rather than storing it in a
               buffer for parsing.
           ^t  Set timeout to the value represented by the decimal
               digits that follow.  The default timeout is 20
               seconds. Note that this timeout may be overridden
               by a smaller serialTimeout configured for the

               associated serial interface (see serialConfigTable).
           ^w  Wait for the reply string that follows which is
               terminated by the next command or the end of string.
               Partial and case insensitive matching is applied, ie.
               if the reply string (any case combination) is found
               anywhere in the received string, then the a match is
               found.  If the current timeout elapses without a match,
               then the remaining control string is ignored.
           ^!  The ^ character.
           ^d  Delay the number of seconds specified by the decimal
               digits that follow.
           ^b  Send break for the number of milliseconds specified by
               the decimal digits that follow.  If no digits follow,
               break will be enforced for 250 milliseconds by default.

        The following ASCII control characters may be inserted into
        the `^s' send string or the `^w' reply string:

           ^@    0x00
           ^A    0x01
            ..
           ^M    0x0D
            ..
           ^Z    0x1A
           ^[    0x1B
           ^    0x1C
           ^]    0x1D
           ^^    0x1E
           ^_    0x1F

        Binary data may also be inserted into the data stream.  The
        control sequence for each byte of binary data is ^0x##, where
        ## is the hexadecimal representation of the data byte.  Two
        ASCII characters (0-9, a-f, A-F) must follow the `^0x'
        control prefix.  For example, `^0x0D^0x0A' is interpreted as a
        carriage return followed by a line feed."
