The HeartBeat module is designed to provide in-depth monitoring for your Magento site. There are two ways to monitor the status of your site – via an XML report or through Pingdom.
Pingdom is monitoring service that tracks all website & server vitals in one convenient monitoring platform. It helps you spot performance trends, share data with others, and helps with issue resolution. Pingdom also sends users real-time updates via email, SMS (texts), Twitter, or mobile notification via iOS or Android devices.
The HeartBeat module monitors seven components that are vital for site functionality and performance of any Magento website. These tests include: API availability, database, flat table, logs, catalog, file system, and indexes.
