Displaying Error Stream Data

By default, error streams are LOCAL, but you can make their information available outside of the project.

In production mode, project monitoring may be performed externally. .

  1. In the Visual editor, open the project.
  2. To enable real-time monitoring of errors encountered by the project, click the Typeicon in the Error Stream to toggle it from LOCAL to OUTPUT.
  3. To enable ad hoc SQL queries, add a window (for example, ErrorState) to the project, downstream from the error stream.
    The ErrorState window preserves the state of the error stream so it can be queried using the esp_query utility.
