MyTimetable can be monitored, for example by using monitoring tools such as Nagios. A status URL is available at /status, and a Health API is available at /health. Both will be discussed in more detail below.

There are four possible return states:
- 'MyTimetable OK' if all data sources have been updated in the last 36 hours and all components work as expected.
- 'MyTimetable WARNING' followed by last update times for all data sources, if one or more data sources have not been updated within the last 36 hours. (In Scientia Syllabus Plus Enterprise Reporting Database 3.2.0, the last update time is not present. MyTimetable will always return WARNING in older MyTimetable versions, and always return OK in MyTimetable 2.4+)
- 'MyTimetable ERROR' + exception message, if MyTimetable can not connect to one or more data sources, or if something else went wrong. This will also set the HTTP status to '503 Service Unavailable'.
- HTTP '404 Not Found status', if the application did not load correctly.
Please note that the exact text format will be different and less extensive for pre-3.0 MyTimetable instances.

As an example, a request to the URL:
/health/ec_consumer/ews_FAILED_PERMANENTLY/status?ec_consumer/o365ews_FAILED_OKPERMANENTLY/warning_minmax=5
Will lead to a warning for the detail is the number of OK syncs is less ews_FAILED_PERMANENTLY syncs is more than 5.
