Adding Devices to PRTG:

1. Log in to your PRTG Network Monitor dashboard.
2. Navigate to the "Devices" tab and click on "Add Device."
3. Enter the IP address or hostname of the network device.
4. Select the appropriate device template for monitoring.
5. Follow the on-screen instructions to complete the device setup.

Configuring SNMP or SSH Sensors:

1. After adding the device, navigate to the "Sensors" tab.
2. Click on "Add Sensor" and select either SNMP or SSH, depending on device support.
3. For SNMP, choose the SNMP sensor appropriate for your device model.
4. For SSH, select the SSH sensor and configure SSH credentials for accessing the device.
5. Save the sensor settings to initiate configuration monitoring.

Enabling Configuration Monitoring:

1. Once the sensor is added, navigate to its settings.
2. Enable configuration monitoring by selecting the appropriate option.
3. Configure settings such as the polling interval and retention period for configuration data.
4. Save the sensor settings to start monitoring network device configurations.

Monitoring Configuration Changes:

1. Access the sensor's dashboard to view configuration change data.
2. Monitor configuration change events, including modifications, additions, and deletions.
3. Utilize real-time alerts to receive notifications when configuration changes occur.
4. Review detailed change logs to identify the nature and scope of configuration modifications.

Comparing Configurations:

1. Use PRTG's configuration comparison feature to compare current and previous configurations.
2. Identify differences between configurations, such as altered settings or added/deleted entries.
3. Analyze configuration deltas to understand the impact of changes on network performance and security.
4. Leverage comparison reports for auditing and compliance purposes.

Automating Configuration Backups:

1. Set up automated configuration backups using PRTG's scheduling feature.
2. Configure scheduled tasks to perform regular backups of device configurations.
3. Store backup files securely and retain historical backups for auditing and disaster recovery purposes.
4. Utilize backup restoration capabilities to quickly restore configurations in the event of network issues or failures.

Integration with IT Infrastructure:

1. Integrate configuration change monitoring data with other IT infrastructure components in PRTG.
2. Correlate configuration change events with network performance, security incidents, and compliance violations for comprehensive insights.
3. Use PRTG's mapping feature to visualize network devices and their configuration change status within your network topology.
4. Leverage APIs for further integration with third-party configuration management tools or custom applications.

By effectively monitoring network device configuration changes with PRTG Network Monitor, organizations can ensure network integrity, security, and compliance. Follow the steps outlined in this guide to maximize the benefits of configuration change monitoring within your IT infrastructure.
