1. System Logs: The system logs contain information about various events that occur on the firewall, including the commit process. The administrator can review the system logs to verify whether the commit completed successfully or whether there were any errors or warnings during the commit process.
2. Task Manager: The task manager displays a list of all active tasks on the firewall, including the commit task. The administrator can use the task manager to check the status of the commit task, including whether it is in progress, completed successfully, or failed.

Both templates and template stacks support variables. Variables allow you to create placeholder objects with their value specified in the template or template stack based on your configuration needs. Create a template or template stack variable to replace IP addresses, Group IDs, and interfaces in your configurations. https://docs.paloaltonetworks.com/panorama/10-0/panorama-admin/manage-firewalls/manage-templates-and-template-stacks/override-a-template-setting.html
