ETL jobs, which insert records into the Teradata Database, issues a command similar to the one described. This command sends an event message in each stage before the insert job begins.
sendevent --tds TD1 -e SanDiego -r ETL1 -t Load -s ETL1 -w csload080518am --et START -m ‘start customer load’ --wts ‘2008-05-18 11:35:28’ -u etlroot
The UOW ID is the literal value passed following the -w parameter.
Or
sendevent --tds TD1 –e SanDiego -r ETL1 -t Load -s ETL1 --gt /opt/teradata/sload --et START -m ‘start customer load’ --wts ‘2008-05-18 11:35:28’ -u etlroot
The second command obtains the UOW ID from the file identified after the --gt parameter.
The parameters used in the sendevent command are:
- TDPID (--tds)
- [REQUIRED] The name of the Teradata system from which the event is sent.
- Ecosystem (-e)
- The name of the ecosystem from which the event is sent. This is commonly the name of a data center. It represents all the components that are related to one production Teradata system, including ETL servers, BI servers, and so forth.
- Resource (-r)
- [REQUIRED] The name of the resource that is sending the event. Typically, this is the name of the job that is being run. It can be any type of resource, component, job, or data health check.
- Resource Type (-t)
- [REQUIRED] The type of resource that is sending the event. The resource type is not fixed; however, the default configuration includes the following types:
| Resource Type | Description |

| CPUSOFTIRQ | Percent of CPU used to service software interrupts. Averaged across all logical cores. |
| CPUSTOLEN | Percent of CPU used is taken away from an executing process and flagged as able to be run. Typically, a non-zero in virtual machines that share CPU. Averaged across all logical cores. |
| CPUSYSTEM | Percent of CPU used in kernel mode. Averaged across all logical cores. |
| CPUUSAGEPCT | Percent of CPU used on the system. Averaged across all logical cores. |
| CPUUSER | Percent of CPU used in user mode. Averaged across all logical cores. |

- System Identifier (-s)
- Describes the system from which the event is sent.
- Unit of Work Identifier (-w)
- [REQUIRED unless --gt is specified]
- Get Unit of Work Identifier (--gt <filename>)
- [REQUIRED if no -w is specified]
sendevent sends the UOW ID found in the <filename> specified.
- Message (-m)
- A message included with the event for reporting purposes.
- Unit of Work Timestamp (--wts)
- The unit of work time stamp. Reflects the freshness of data contained within the unit of work. For example, UOWId SalesData20080502 contains sales data extract as of May 02, 2015.
This time stamp is used to determine job latency across ecosystems. When job schedules are used, this time stamp falls between the start and end time stamp of the corresponding data cycle to mark the data cycle as completed.
When it is not specified, a unit of work time stamp defaults to the event time stamp of the first event where the specific unit of work appears.
- User Identifier (-u)
- A unique identifier for the user of the system. This is not necessarily the same as the system login username.
