Troubleshooting Guide for device-certificate-report

Encountering issues while using the device-certificate-report tool is not uncommon, especially when dealing with complex network environments and certificate management. This guide provides troubleshooting steps for common problems you might face during the report generation process, including connections through Panorama or individual firewalls.

Common Issues and Solutions

1. Connection Issues

Problem: The script fails to connect to the Panorama device or firewall.

Solution: Ensure that the Panorama's or firewall's hostname/IP and credentials are correct. Verify network connectivity and accessibility. Check firewall rules and ensure the necessary ports are open.

2. CSV File Issues

Problem: The script fails to process the provided CSV file.

Solution: Verify the CSV file format and content. Ensure it follows the expected structure and contains all required fields. Check for any special characters or formatting issues that might cause parsing errors.

3. Report Generation Failures

Problem: The script stops during the report generation process.

Solution: Check the Panorama, firewall, and network settings. Make sure the devices are responding correctly. Review the logs for specific error messages.

4. Script Hangs

Problem: The script hangs or does not progress.

Solution: Interrupt the script (Ctrl+C) and check the log files for any clues. Common issues might be network latency or device response delays.

5. Incorrect Certificate Information

Problem: The generated report contains incorrect or outdated certificate information.

Solution: Verify that Panorama and firewalls have the most up-to-date information. Ensure that the devices are properly connected and synced.

6. PDF Generation Issues

Problem: The script fails to generate the PDF report.

Solution: Check if the required PDF generation libraries are properly installed. Ensure there's enough disk space for report generation. Verify permissions for writing to the output directory.

7. Incomplete Device Information

Problem: The report is missing information for some devices.

Solution: Check the connectivity between Panorama, firewalls, and the script. Verify that all devices are properly registered and communicating.

8. Version Compatibility Issues

Problem: The script reports incompatibility with certain PAN-OS versions.

Solution: Ensure that the device-certificate-report tool is up-to-date and compatible with the PAN-OS versions in your environment. Check the documentation for supported versions.

9. Memory Issues

Problem: The script runs out of memory when processing a large number of devices.

Solution: Consider running the script on a machine with more RAM. If possible, process the devices in smaller batches.

10. API Rate Limiting

Problem: The script encounters API rate limiting errors when querying Panorama or firewalls.

Solution: Implement backoff and retry logic. Consider adding delays between API calls or reducing the concurrency of requests if processing multiple devices simultaneously.

General Tips

  • Always ensure you're using the latest version of the device-certificate-report tool.
  • Keep Panorama and managed firewalls updated to the latest compatible versions.
  • Review the logs for detailed error information.
  • For large environments, consider running the script in batches to manage resource usage.
