Sniff Test tool

The Sniff Test displays data as it travels from one step to another in the stream. The Sniff Test is designed to be used as a supplement to logs so that you can debug complex situations.

Note: Applying a Sniff Test slows transformation run speed, so use with care.

To use this, complete these steps:

1. Right-click a step in the transformation as it runs.

2. Select Sniff Test During Execution.

   There are three options in this menu:

   • Sniff test input rows - Shows the data inputted into the step.

   • Sniff test output rows - Shows the data outputted from the step.

   • Sniff test error handling - Shows error handling data.

After you have selected an option, values in the data stream appear. You are also able to observe throughput.
