We are very excited to inform that we have developed a WordPress Plugin which will allow to know all the scheduled events running on a WordPress site. These events may be active by hosting site, by some plugin, or could be set manually, etc.
You can download this plugin at https://wordpress.org/plugins/cron-time/
Plugin allows to know WordPress Hook Name which initiated the scheduled task on the website; schedule after which the event is set to reoccur and time intervals (in seconds).
It can be used for debugging if there is any suspicious program running on website causing repeated errors on website or to track if set cron events are running successfully in the background.
