This page provides examples of what your input and output data might look like in your stream’s Validate function after your stream has been run at least once. These views can help you with troubleshooting troubleshoot and validating validate that the function is working works as intended.
Here are some example streams that use the Validate function. These pre-configured streams can be found and executed from the Usage Engine platform for learning. See https://infozone.atlassian.net/wiki/x/rMB3 for more details.

Example - Validate Function configuration, input, and output data from the example stream ‘Printing As A Service’. In the example stream Printing As A Service, Several validation rules have been created on various fields. One of these rules is on the field, printerId. It has a key of type and a value of integerwhich means the function will check to make sure that the printerId is an integer. In the function’s input data, we can see that one record that has an invalid printerID, “invalidShouldBeInt”. In the output data the record is missing as it has been removed during the validation process.   |
