General Settings

Go to System -> Event Watcher and Notification -> Settings. You will see the following settings:

Events

Allowed Error Level - allows you to select registered error levels by the extension.

Note
The Error event has multiple levels, the low-level errors (Debug, Info, Notice, Warning) generate too many records that are registered by our extension and stored in the DB table mst_event_event.
Therefore in order to avoid the fast overflow of this table, we recommend you to observe only high priority error levels.
