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. .
- In the Visual editor, open the project.
- 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.
- 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.
