Description The table of connectivity unit events. Errors, warnings, and information should be
reported in this table.
Note (v3.0 only) This table contains the 64 most-recent event log entries.
(v4.0 only) This table contains the 255 most-recent event log entries.
(v4.2 only) This table contains the 2048 most-recent event log entries.
(v4.4 only) This table contains the 1024 most-recent event log entries.
Only external RAS log messages are supported. Fabric OS v4.4.0 does not have Panic
or Debug level messages. All messages are documented in the Fabric OS System
Error Message Reference Manual.
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. It is recommended that this
table is 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 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.
