Monitoring and health checks are essential for ensuring the ERP system's stability, performance, and availability. The following aspects are covered:

System Monitoring

The ERP system incorporates real-time system monitoring to track its health, performance, and security. System monitoring involves collecting and analyzing various metrics, such as CPU usage, memory utilization, network traffic, and response times. Real-time monitoring helps identify potential issues, performance bottlenecks, and security threats, enabling proactive actions to maintain system stability and performance.

Alerting

Automated alerting mechanisms are in place to notify administrators of any system anomalies or performance degradation. Alerts are triggered based on predefined thresholds or conditions, such as high CPU usage, low disk space, or abnormal system behavior. Alerting ensures that administrators are promptly notified of any issues, allowing them to take immediate action and minimize the impact on system performance and availability.

By implementing monitoring and alerting mechanisms, the ERP system ensures proactive system management, early issue detection, and timely response to maintain optimal system performance.

Documentation and Training

Comprehensive documentation and training resources are provided to support users and administrators in effectively using and managing the ERP system. The following aspects are covered:
