Example report for showing nodes that have priority Custom Properties not filled in. Empty values means that anywhere you are using that custom property will not be as effective because those nodes won't apply. For example, in the report we are using a CP titled "Decommissioned_Date" which we may be using in an alert. That alert won't catch any of these devices due to the field not being filled out. Use a similar report in your environment to find devices that may be escaping your filtering, alerting, other reporting, etc.
