Our Magento 2 extension Cron Scheduler has an easy set up process and it can be easily accessed in the admin panel. The user is given total control over any cron job running processes and among many other features, we have given the user the ability to schedule, kill, delete and enable any cron job function. If you would like to view the longest running cron job on the system you can simply view it on the Magento Dashboard.
While working on cron job, if any fatal error is encountered or if any cron job is missed, an administrator would be notified through email, once the admin panel is configured for notifications. A user can easily view the actual load placed on the system by cron jobs using parameters like CPU usage, memory usage, and system usage. Also, if a job fails, cron job can automatically kill the longest running job without changing the cron status.
Additionally, we have designed a beautiful timeline feature where users can find a graphical view of each cron job.
