connUnitEventEntry
OID 1.3.6.1.3.94.1.11.1
Description Each entry contains information on a specific event for the given connectivity unit.
Index connUnitEventUnitId
connUnitEventIndex
connUnitEventUnitId
OID 1.3.6.1.3.94.1.11.1.1
Description The connUnitId of the connectivity unit that contains this event table.
Note Same as connUnitId.
connUnitEventIndex
OID 1.3.6.1.3.94.1.11.1.2
Description Each connectivity unit has its own event buffer. As it wraps, it might write over previous
events. This object is an index into the buffer. HP recommends that this table be read
using getNext commands to retrieve the initial table.
The management application should read the event table at periodic intervals and then
determine whether 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 might be
events that might not be contained in the agent's internal event buffer.
For Example:
An agent might read events 50-75.
At the next read interval, connUnitEventCurrID is 189. If the management application
tries to read event index 76 and the agent's internal buffer is 100 entries maximum,
event index 76 is no longer available.
The index value is an incrementing integer starting from 1 every time there is a table
reset. On table reset, all contents are emptied and all indices are set to 0. 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 causes the index value to roll over and start at 1 again.
Note Mapped to swEventIndex.
connUnitEventId
OID 1.3.6.1.3.94.1.11.1.3
Description The internal event ID. Incremented for each event, ranging between 0 and
connUnitMaxEvents. Not used as table index to simplify the agent implementation. When
the ID reaches the end of the range specified by connUnitMaxEvents, it rolls over to start
at 0. This value is set back to 0 at reset. The relationship of this value to the index is that
internal event ID might represent a smaller number than a 32-bit integer (for example,
maximum 100 entries) and would have a value range only up to connUnitMaxEvents.
Note Same function as connUnitEventIndex.
