Workload Designer can generate alerts for either an event or an exception.
- Events can be:
- Planned or scheduled, such as a weekend time period begins
- Unplanned, such as a node going down
- Exceptions are generated when a query exceeds some user-defined threshold.
TDWM generates the alerts using the DBCMNGR.AlertRequest table, using the same mapping as the Alert Request data collector. The contents of the jobName, message, and description columns are specified by the TDWM software.
The following table illustrates the mapping.
| Teradata Alerts SNMP Fields | Value | TDWM-Specific Contents |
|---|---|---|
| alertId | 0 (unused) | |
| alertName | AlertRequest.jobName | TDWM: HostID=hostId, SesNum=sessionNumber, ReqNum=requestNumber |
| source | Viewpoint | |
| systemName | Teradata system for which the Alert Request data collector is configured | |
| severity | Low | |
| details | The message or description, as configured in the default SNMP delivery settings:
|
Message for exception: TDWM: WD worlkloadName encountered exception 'exceptionName' which resulted in 'action' Message for event: TDWM: Expression 'eventName'' was triggered Description for exception: TDWM: WDId: workloadId, ExceededCriteria type=type Description for exception: EventName |
