GSLog - Scoped, Global

GSLog is a script include that simplifies script logging and debugging by implementing levels of log output, selectable by per-caller identified sys_properties values.

Logs generated using the GSLog API are logged in the System Logs. Specifically, you can find System Logs in the UI by navigating to All > System Logs > System Log. You can choose to view all logs or specific log types like Application Logs, Errors, Script Log Statements, and so on under this menu item. Filtering the Source column in the All logs view can help locate your entries faster.

Logs can be at the level of debug, info, notice, warning, err, or crit (after BSD syslog.h and followers). The default logging level is notice, so levels should be chosen accordingly.

Use for any server-side script where you want to implement event logging.

For more information, see Debugging scripts.
