Using Performance Graphs

If you configured step performance monitoring, with database logging (optional), you can view the performance evolution graphs. Performance graphs provide you with a visual interpretation of how your transformation is processing. To enable database logging, enable the option Enable step performance monitoring within the Transformation Properties / Monitoring dialog box.


Follow the instructions below to set up a performance graph history for your transformation.

  1. Right-click in the workspace (canvas) where you have an open transformation. Alternatively, press <CTRL +T>. To enable the logging, you also need to enable the option Enable step performance monitoring in the Transformation Properties/Monitoring in the dialog. The Transformation Properties dialog box appears.
  2. In the Transformation Properties dialog box, click the Logging tab. Make sure Performance is selected in the navigation pane on the left.
  3. Under Logging enter the following information:
