If you'd like to have a more visual indication of the status of your cron jobs, you would need to implement a custom solution, as it's not a standard feature of cron. You could create a script or use a tool that maintains a separate configuration file to track the status of each cron job and then display that information in a user-friendly way. This would require some programming and system administration skills.
Additionally, if you're experiencing issues with osTicket after a MySQL update, you should investigate and resolve those issues to ensure the smooth operation of your ticketing system. Disabling the cron job is a temporary solution, and you should aim to fix the underlying problem.
