Event table
The objects described in this section are in a table format indexed by World Wide Name and
Index. The maximum index is determined based on the number of events in the table. An
example of how to access one of these objects given a WWN of 100000c0dd0090a7 is:
"snmpget localhost public
fcmgmt.connSet.connUnitEventTable.connUnitEventEntry.connUnitEventUnitId.
16.0.0.192.221.0.144.167.0.0.0.0.0.0.0.0.1".
connUnitEventUnitId (1.3.6.1.3.94.1.11.1.1)
The connUnitId of the connectivity unit that contains this event table.
■ Syntax—FcGlobalId
■ Access—Read-only
■ Status—Mandatory
■ Return value—World Wide Name of the switch (for example, 10 00 00 C0 DD 00 71 C9
00 00 00 00 00 00 00 00)
connUnitEventIndex (1.3.6.1.3.94.1.11.1.2)
Each connectivity unit has its own event buffer. As it wraps, it can write over previous events.
This object is an index into the buffer. HP recommends that this table be read using getNexts
to retrieve the initial table. The management application reads the event table at periodic
intervals and determines if any new entries were added by comparing the last known index
value with the current highest index value. The management application updates its copy of
the event table. If the read interval is too long, it is possible that there can 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, connUnitEventCurrID is 189. If the management application
tries to read event index 76, and the agent's internal buffer is 100 entries max, event index 76 is
no longer 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 indexes 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 causes the index
value to roll over and start at one again.
