One of the most common questions we receive from APM customers is: Which out-of-the-box (OOB) APM fields should we use? What is the ‘best practice’ or ServiceNow’s guidance on using OOB fields?

As with most ServiceNow applications, adding new fields in APM to a business application record is easy, and in most cases necessary. Application attributes are specific to a customer context, and depend on the outcomes and stakeholders. However, there are some OOB fields that drive OOB dashboards, reports, and other analysis. Using these fields will reduce the configuration effort, and allow use of OOB functionality.
