2. Log in using your credentials to access the dashboard.

Step 2: Adding SNMP Device Interface Sensor

1. Navigate to the "Devices" or "Groups" section where you want to add the sensor.
2. Click on the "Add Sensor" button.
3. Search for the "SNMP Traffic" sensor type and select it.
4. Choose the target device for which you want to track interface showstoppers.
5. Configure sensor settings such as SNMP version, community string, and scanning interval.

Step 3: Configuring SNMP Device Interface Sensor

1. Once the sensor is added, click on it to access its settings.
2. Under the "Settings" tab, configure parameters specific to tracking interface showstoppers.
3. Enable monitoring for the desired interfaces.

5. Customize notification methods (email, SMS, etc.) and severity levels for alerts.
6. Save the settings to apply the changes.

Step 4: Reviewing Monitoring Results

1. After configuring the sensor, PRTG will start tracking SNMP device interface showstoppers.
2. Access the sensor overview to view real-time data and status updates.
3. Monitor showstoppers triggered by interface conditions exceeding configured thresholds.
4. Utilize built-in reporting and graphing features to visualize showstopper trends over time.
5. Review showstopper history and actions taken for resolution.

Step 5: Troubleshooting and Maintenance

1. In case of any issues or discrepancies, review sensor logs and error messages for troubleshooting.
2. Ensure that SNMP is enabled and properly configured on the target device.
3. Verify that the device's SNMP settings and credentials are accurate in PRTG.
4. Check network connectivity between the PRTG server and the target device.
5. Regularly review and adjust showstopper settings based on changing network conditions and requirements.
6. Keep PRTG Network Monitor updated to the latest version to benefit from enhancements and bug fixes.
