An online monitoring system is a tool used to continuously track and analyze data from various sources in real-time. These systems are often employed in different industries to ensure that operations run smoothly and to quickly address any issues that arise. Here’s a simple breakdown:

Real-Time Data Tracking: The system collects and displays data as it happens, allowing users to see live updates on performance metrics, system statuses, or other key indicators.
Alerts and Notifications: It can be set up to send alerts if certain thresholds are exceeded or if there are anomalies, helping users to quickly address potential problems before they escalate.
These systems are used in various fields, such as IT (for network monitoring), manufacturing (for equipment performance), and environmental management (for pollution levels).
