Config Changes
Config Changes lets you view snapshots of device configuration files collected by automation tasks and compare them against previous states to see exactly what changed. For example, if you run a router configuration backup task daily, this screen shows you line-by-line what differs between yesterday's and today's configuration.
Configuration change history is only collected for tasks that have the Config Change Tracking option enabled at task creation.
