If you're like most of us, you have better things to do than go through your nightly config backup report looking for the devices that have changes.
In fact, this has been brought up numerous times on thwack - Config change report with ONLY changed configs.
The good news is - there's a super easy way to solve the problem. Just select "Send config change details in a separate email" and you'll receive the whole job report as one email, and just the things that changed in a separate email. This option has been available in NCM since v5.5, but it's easy to miss so we wanted to bring it to your attention.
