high unmanaged disk usage on /ngfw.

High unmanaged disk usage on the /ngfw directory could be caused by a variety of factors, including:

1. Large log files: If there are large log files generated by the NGFW (Next-Generation Firewall) software, they can quickly consume disk space. You may need to review the logging configuration and rotate the logs to avoid filling up the disk.

2. Temp files: NGFW software may create temporary files that are not always deleted after they are no longer needed, which can also consume disk space. Check for any temporary files that are no longer required and delete them to free up space.

3. Software updates: NGFW software updates can also consume disk space, especially if the updates are downloaded automatically and stored on the disk. You can review the update configuration to ensure that old updates are removed after a new update has been installed.

4. Configuration backup files: NGFW software may create configuration backup files, which can also consume disk space. If these files are not regularly pruned, they can accumulate and take up space. Check for any backup files that are no longer needed and delete them.

To troubleshoot the issue, you can use the following steps:

1. Use a disk usage analyzer tool to determine which files or directories are consuming the most disk space.

2. Review the NGFW logs and configuration files to determine if any files are growing too large or are no longer needed.

3. Delete any files or directories that are no longer needed.

4. Configure log rotation and backup retention policies to avoid filling up the disk.

5. Consider adding more storage to the system to accommodate future growth.
