All categories of settings and shell script files stored on the Zyxel Device will be included in the diagnostic file.
Click Maintenance > Diagnostics to open this screen. Click Collect Now to have the Zyxel Device create a new diagnostic file.

View Log
Log messages are stored in two separate logs, one for regular log messages and one for debugging messages. In the regular log, you can look at all the log messages by selecting All Logs, or you can select a specific category of log messages (for example, user). You can also look at the debugging log by selecting Debug Log. All debugging messages have the same priority.
Click Maintenance > Log > View Log to open this screen.
When a log reaches the maximum number of log messages, new log messages automatically overwrite existing log messages, starting with the oldest existing log message first.Events that generate an alert (as well as a log message) display in red. Regular logs display in black. Click a column’s heading cell to sort the table entries by that column’s criteria. Click the heading cell again to reverse the sort order.
The Web Configurator saves the filter settings once you click Search. If you leave the View Log screen and return to it later, the last filter settings would still apply.
