After you configure the ETL, you can run it to collect data. You can run the ETL in the following modes:

A. Simulation mode: Only validates connection to the data source, does not collect data. Use this mode when you want to run the ETL for the first time or after you make any changes to the ETL configuration.

B. Production mode: Collects data from the data source.

To run the ETL in the simulation mode:

1. In the TrueSight Capacity Optimization console, navigate to Administration > ETL & System Tasks, and select ETL tasks.
2. On the ETL tasks page, click the ETL. The ETL details are displayed.
   
3. In the Run configurations table, click Edit  to modify the ETL configuration settings.
4. On the Run configuration tab, ensure that the Execute in simulation mode option is set to Yes, and click Save.
5. Click Run active configuration. A confirmation message about the ETL run job submission is displayed.
6. On the ETL tasks page, check the ETL run status in the Last exit column.
   OK Indicates that the ETL ran without any error. You are ready to run the ETL in the production mode.
7.  If the ETL run status is Warning, Error, or Failed:
   1. On the ETL tasks page, click  in the last column of the ETL name row.
   2. Check the log and reconfigure the ETL if required.
   3. Run the ETL again.
   4. Repeat these steps until the ETL run status changes to OK.

You can run the ETL manually when required or schedule it to run at a specified time.

1. On the ETL tasks page, click the ETL. The ETL details are displayed.
2. In the Run configurations table, click Edit  to modify the ETL configuration settings. The Edit run configuration page is displayed.
3. On the Run configuration tab, select No for the Execute in simulation mode option, and click Save.
4. To run the ETL immediately, click Run active configuration. A confirmation message about the ETL run job submission is displayed.
   When the ETL is run, it collects data from the source and transfers it to the TrueSight Capacity Optimization database.

By default, the ETL is scheduled to run daily. You can customize this schedule by changing the frequency and period of running the ETL.

To configure the ETL run schedule:

1. On the ETL tasks page, click the ETL, and click Edit. The ETL details are displayed.
   

2. On the Edit task page, do the following, and click Save:

   • Specify a unique name and description for the ETL task.
   • In the Maximum execution time before warning field, specify the duration for which the ETL must run before generating warnings or alerts, if any.
   • Select a predefined or custom frequency for starting the ETL run. The default selection is Predefined.
   • Select the task group and the scheduler to which you want to assign the ETL task.

3. Click Schedule. A message confirming the scheduling job submission is displayed.
   When the ETL runs as scheduled, it collects data from the source and transfers it to the TrueSight Capacity Optimization database.
