This Magento 1 module schedules a cron job to send a HTTP GET request to healthchecks.io monitoring service (or a similar service) every hour. When the cron jobs are not running per the expected schedule, healthchecks.io will send a notification to the store owner. It is then a good idea to check if other Magento cron jobs are running normally.
This monitoring setup will detect various failure scenarios, including:
- system's cron daemon is not running
- Magento cron job runner crashes on startup
- One of the Magento cron jobs runs longer than expected and blocks other jobs from running
System->Configuration->Advanced->System->Cron Here you will find two fields: 'Enable healthchecks' and 'Healthcheck ping URL'. If 'Enable healthchecks' is set to 'No', cron job will still be scheduled, it just will not do anything.
