How to Monitor Scheduled Events in MySQL

There are two ways to see error logs of scheduled events on MySQL:

1. Check the MySQL error log file. The MySQL error log file is a text file that contains all of the error messages that the MySQL server has generated. If a scheduled event fails, an error message will be written to the error log file. The error log file is typically in the /var/log/mysql directory on Linux or Windows.
2. Use the SHOW EVENTS statement with the ERRORS option. The SHOW EVENTS statement can be used to list all of the scheduled events in a MySQL database. The ERRORS option will only list the scheduled events that have failed. The following SQL statement will list all of the scheduled events in the my_database schema that have failed:

SHOW EVENTS IN my_database WHERE ERRORS;

The SHOW EVENTS statement will return a table of information about each scheduled event. The table will include the following columns:

• EVENT_NAME: The name of the event.
• DEFINER: The user who created the event.
• TIME_ZONE: The time zone that the event is scheduled in.
• EVENT_BODY: The SQL statement that the event executes.
• EVENT_TYPE: The type of event (one-time or recurring).
• EXECUTE_AT: The date and time that the event is scheduled to execute.
• INTERVAL_VALUE: The interval between event executions for recurring events.
• INTERVAL_FIELD: The interval field for recurring events.
• STARTS: The start date and time for recurring events.
• ENDS: The end date and time for recurring events.
• STATUS: The status of the event (enabled or disabled).
• ERRORS: The number of errors that have occurred during the execution of the event.

If the ERRORS column for a scheduled event is greater than 0, then the event has failed. The SHOW EVENTS statement will also include the error messages generated when the event failed.
