Table 90 Events tab fields
Field Description
Index This index uniquely identifies an entry in the event table. Each entry
defines one event that is to be generated when the appropriate
conditions occur.
Description Specifies whether the event is a rising or falling event.
Type The type of notification that the Device Manager provides about this
event. In the case of log, an entry is made in the log table for each
event. In the case of trap, an SNMP trap is sent to one or more
management stations. Possible notifications follow:
• none
• log
• trap
• log-and-trap
Community The SNMP community string acts as a password. Only those
management applications with this community string can view the
alarms.
LastTimeSent The value of sysUpTime at the time this event entry last generated an
event. If this entry has not generated any events, this value is zero.
Owner If traps are specified to be sent to the owner, then this is the name of
the machine that will receive alarm traps.
Status Normally valid. A not-valid field indicates that an SNMP agent other
than the Device Manager has tried to modify an RMON parameter or
that network conditions have corrupted an SNMP packet sent by the
Device Manager. The status would temporarily appear as “under
creation” and then the status would become either “valid” or the field
would be deleted.
