Table A-34
Event Table
FA MIB Object Name Type Product Mapping Access Description
*fcConnUnitEventIndex Unsigned32 An event index. R Each connectivity unit has its own event
buffer. As it wraps, it may write over
previous events. This object is an index
into the buffer. It is recommended that
this table be read using ‘getNext’s to
retrieve the initial table. The management
application should read the event table at
periodic intervals and then determine if
any new entries were added by
comparing the last known index value
with the current highest index value. The
management application should then
update its copy of the event table. If the
read interval is too long, it is possible that
there may be events that may not be
contained in the agent’s internal event
buffer. For example, an agent may read
events 50-75. At the next read interval,
fcConnUnitEventCurrID is 189. If the
management app tries to read event
index 76, and the agent’s internal buffer is
100 entries max, event index 76 will no
longer be available. The index value is an
incrementing integer starting from one
every time there is a table reset. On table
reset, all contents are emptied and all
indices are set to zero. When an event is
added to the table, the event is assigned
the next higher integer value than the last
item entered into the table. If the index
value reaches its maximum value, the
next item entered will cause the index
value to roll over and start at one again.
FcConnUnitREventTime DisplayString
(SIZE (15)) The time when the event
occurred. R This is the real time when the event
occurred. It has the following format:
DDMMYYYY HHMMSS
DD = day number, MM = month number,
YYYY = year number, HH = hour number,
MM= minute number, SS = seconds
number
If not applicable, return a NULL string.
