• Navigate to the "Devices" tab in the PRTG web interface and click on "Add Device".
• Enter the IP address or hostname of the servers and storage devices you want to monitor for disk space usage.
• Provide the necessary authentication credentials (SSH, WMI, SNMP, etc.) to access the devices.
• PRTG will automatically discover the available sensors on the devices, including disk space monitoring sensors.

 Configuring Disk Space Monitoring Sensors:

• Once the devices are added, navigate to their respective sensors to configure disk space monitoring.
• Select the appropriate disk space monitoring sensor based on your device type and requirements (e.g., SNMP Disk Free Sensor, WMI Free Disk Space Sensor).
• Configure the sensor settings, such as the threshold for warning and error states, polling interval, and disk volumes to monitor.

 Dashboard Customization:

• Customize your PRTG dashboard to display relevant disk space usage metrics and graphs.
• Add widgets to visualize real-time and historical disk space usage data, such as available disk space, disk usage percentage, and trends over time.
• Arrange the layout of the dashboard to highlight critical disk space metrics and facilitate quick analysis.

Setting Up Alerts:

• Configure alerts to be notified of low disk space conditions on your servers and storage devices.
• Define alert thresholds based on acceptable disk space levels for your environment.
• Choose notification methods such as email, SMS, or push notifications to ensure timely awareness of disk space issues.

 Historical Data Analysis:

• Utilize PRTG's historical data storage to analyze trends in disk space usage over time.
• Generate reports to gain insights into disk space usage patterns, disk space growth rates, and trends.
• Compare historical disk space data across different devices or device groups to identify common sources of disk space consumption.

 Capacity Planning and Optimization:

• Use disk space monitoring data to plan for future storage capacity needs and optimize disk space utilization.
• Identify devices or disk volumes experiencing rapid disk space growth and take proactive measures to address potential storage constraints.
• Implement storage management strategies such as data archiving, disk cleanup, and storage tiering to optimize disk space usage.

 Integration and Automation:

• Integrate PRTG with other IT management tools and systems through APIs or custom scripts to enhance its functionality.
• Automate disk space monitoring tasks such as alert acknowledgments, disk space cleanup workflows, and remediation actions.
• Leverage third-party integrations to extend PRTG's capabilities for advanced disk space analysis and reporting.

 Maintenance and Updates:

• Regularly update PRTG to ensure you have access to the latest features, performance improvements, and security patches.
• Monitor the health of your PRTG installation, including server resources, database performance, and sensor status.
• Perform routine maintenance tasks such as database cleanup, sensor optimization, and configuration backups to ensure the reliability and accuracy of disk space monitoring data.

By following these steps and best practices, you can effectively track disk space usage on servers and storage devices using PRTG Network Monitor, enabling you to optimize storage capacity and ensure the availability of critical data storage resources.
