This part of the Blueworx Voice Response MIB tree can be used in generating SNMP traps from Blueworx Voice Response.
There are two ways in which alarms can be notified to an SNMP manager. One is the straightforward way of sending a trap for each alertable alarm. These are known as simple traps. The enterprise specific trap number for this trap is 1000001. This trap contains the following information:
alarmSequence |
Alarm sequence number. |
alarmID |
The unique number that identifies the alarm message. An explanation of each is available in the Problem Determination information. |
alarmTime |
The time at which the alarm was recorded. |
alarmClass |
Severity:
|
alarmMessage |
Brief message text. |
alarmErrno |
AIX errno value. |
parmCount |
The number of parameters. |
alarmParmValue |
The parameter values themselves. |
The other way is to implement trap-directed polling. With this, a single summary trap is sent whenever one or more alertable alarms occur within a certain configurable time, for example, 5 seconds. This trap lists the alertable alarms that have occurred in that time. The network management application can then get the alarm data in one, or only a few, GET requests. In this way the network management application is in control of the SNMP traffic, and can delay getting the alarm details if necessary to avoid excessive network load. These are known as summary traps. The enterprise specific trap number for this trap is 1000002. This trap contains the following information:
dtTrapAlarmTotal |
The number of alarms returned in this trap. |
latestSequence |
The sequence number of the last alarm in the trap. |
earliestSequence |
The sequence number of the first alarm in the trap. |
alarmID |
The alarm identifiers. |
Trap-directed polling is selected by specifying the -p flag on the dtsnmpd command (see dtsnmpd command). Both the maximum delay before sending the summary trap and the maximum number of alarms notified in this trap type can be specified through -n and -t command line options on the dtsnmpd command.
See Alertable alarms and DTalarm command for related information.
There is a single enterprise specific trap to notify a manager that Blueworx Voice Response has changed operating status. This is normally used by a network management application to detect Blueworx Voice Response starting up and shutting down. During normal operation, the status would not be expected to change.
The enterprise-specific trap number for this trap is 1000003. This trap is described in the Trap-types section of the MIB as dtStatusChange. The trap contains the new state of the Blueworx Voice Response system, using the dtStatus variable from the dtResources portion of the MIB.
This MIB group is used for any variables specific to TRAPs only. They will only appear in traps and cannot be otherwise be read or written.
