Netdata in Action:
Imagine you have a server running critical applications, and you want to ensure it’s performing optimally. By installing Netdata on the server, you can access its web interface through a browser. Here’s how Netdata works in action:
Real-Time Metrics: As soon as you access the Netdata web interface, you’ll see real-time charts displaying various metrics related to CPU, memory, disk, network, and more.
Interactive Interface: The interface is interactive, allowing you to zoom in on specific timeframes, hover over charts to view detailed information, and click on specific metrics to drill down further.
Alarms and Notifications: You can configure alarms for specific metrics. For example, if CPU usage exceeds 90%, Netdata can trigger an alert, allowing you to take action promptly.
Container Monitoring: If you have Docker containers running on the server, Netdata will automatically detect and monitor them, providing insights into container resource usage and performance.
Custom Dashboards: Netdata allows you to create custom dashboards to focus on the metrics that matter most to you and your applications.
Overall, Netdata’s real-time monitoring capabilities enable you to identify performance bottlenecks, troubleshoot issues, and optimize your infrastructure efficiently.
