You added a device for NPM to monitor.

 If you want to see a statistic that NPM does not support out of the box, you can use the Manage Pollers feature in Device Studio or the Universal Device Pollers (UnDP) feature to collect the statistics you want from the device. Both features allow you to create custom monitors for almost any statistic provided by SNMP based on its Management Information Base (MIB) and object identifier (OID). You can also assign the custom pollers to specific devices, view the polled data in the Orion Web Console, and use the data in alerts and reports. The difference between the two features is that Manage Pollers is a web-based interface that simplifies the creation and management of custom pollers, while UnDP is a standalone application that offers more advanced options and flexibility. Device templates and application monitor templates are not features that can be usedto collect custom statistics from devices, as they are predefined sets of monitors for specific device types or applications that NPM supports out of the box. References:
