The Magento 2 System Health Monitor Extension includes a trigger-based alert system that monitors over 15 critical events, including cron failures, disk usage thresholds, cache being unexpectedly cleared, database connections nearing their limit, suspicious file uploads, and admin login failures. Notifications can be routed through email, Slack, or Microsoft Teams via webhook integrations, ensuring the right team member is alerted instantly without needing to manually check the dashboard.
