Comprehensive and Detailed Explanation From Exact Extract:

A node rediscovery updates all node and interface information, including names, IP addresses, captions, and interface aliases. Running a rediscovery on the node ensures all related interface details are refreshed in the SolarWinds database and web console.

For effective network capacity planning:

Enough historical data (at least 7 days) must be available: This ensures meaningful trend and forecast analysis.

Relevant objects (nodes, interfaces, volumes) must be managed: Only managed entities are included in capacity planning calculations.

Polling every OID or updating the MIB database (A, D) is not a direct requirement for capacity planning.

Device Studio pollers are used to build custom pollers for advanced device-specific metrics and widgets. The technologies explicitly supported for Device Studio pollers include:

Machine type for node details widget: Device Studio can create custom pollers to display specific node details, such as machine type, chassis ID, or serial number, within a node details widget.

Power supply status for vital statistics view: Device Studio also allows polling and visualizing metrics such as power supply status, fan status, and other vital statistics that are not natively included in basic SNMP polling.

While Device Studio can poll for advanced or composite data such as VLAN, VRF, and device health, certain interface statistics or single CPU/memory metrics are typically managed by standard SNMP pollers or Universal Device Pollers rather than Device Studio.

Applications and NBAR2 applications in top applications are sorted by bytes: The default sorting for the “Top Applications” view, including NBAR2 apps, is by bytes.

It is possible to combine applications and NBAR2 applications: SolarWinds allows combining standard and NBAR2-classified apps for alerting and reporting purposes.

Exact Extract from Official Guide:

"Top Applications, including NBAR2, are sorted by bytes and you can combine standard and NBAR2 application data in alerts and reports."

The radial gauge display in the SolarWinds web console requires that the polled value from the OID is a numeric type that supports gauge visualizations (for example, a percentage or value with a defined minimum and maximum). If the OID returns data that does not fit these requirements—such as text, status, or a counter with no clear min/max—the gauge option will be grayed out and unavailable for selection. This behavior is explained in the Universal Device Poller documentation, which states that only compatible numeric OID types can be displayed using radial gauge resources.
